Welcome to the Chrono Trigger Speedrun and Advanced Gameplay Techniques section. Here, the Compendium aims to document the fastest Chrono Trigger players alive and the techniques employed to achieve their low times. Other esoteric gameplay information will be presented in addendum, along with pressing issues and possibilities that may shave off even more seconds of playtime. Traditional speedruns are recognized by the [http://speeddemosarchive.com/ Speed Demos Archive], and are videotaped on a console. Emulated speedrun listings also exist, called "tool-assisted speedruns." Emulators are also used for rapidly evaluating new skills and techniques for later application in a traditional attempt. Since a tool-assisted speedrun doesn't exist for Chrono Cross, and since a traditional speedrun has edged out the TAS for Chrono Trigger, the Compendium will cover traditional speedruns. Successful runs have been described as relying on two factors; the first is skill, "that which makes it possible," and the second is luck, "that which makes it happen." Other challenges are presented at end of this area. This page is authored with the help of inichi.

''inichi's notes'': I made a few mistakes...but fortunately, nothing critical. If I redo the run, I probably won't get a faster record; rather, it might be slower...I'm truly satisfied with this record. It was lucky for me to start and finish the run before college starts, as I had enough time to play the game. That is why I was able to make the Chrono Trigger run in such short time...As for the final battle, I fought Lavos at least 500 times, tested various strategies and made the final. Even though it still has room for improvement, I'm glad it could live up to expectations.

''inichi's note'':  The main reason [for the gauge speed change] is to decrease the number of enemies' attacks. You can see the strange space between the second Cyclone and the third one in the R-series battle. If it remained Battle Speed 1, two or three R-series's attacks cuts in that space. It's enough ground for me to change Battle Speed to something slower considering the animation of their attack takes more than 10 seconds, and this battle finishes in a short time -- about 1 minute.

This strategy is one minute faster than the hero's one. Barrier is not very helpful because you have to not only use Barrier on someone but also heal him to survive Dark Matter. After all, the number of times using items is almost the same in a battle without Barrier. Besides, Magus only does nothing between each Dark Matter, which means it would have little effect at a time if the battle finishes a turn or two earlier by using Barrier. Considering it takes at least 25 seconds to get a Barrier, it is best to forget it. [As it turned out, the timing of inichi's Magus battle and Magus's behavior were extremely lucky to the point of nearly total perfection.]

Perhaps, a few physical attacks will be needed. Less number of attacks would save time (10-15 seconds?).

''inichi's note:'' [Changing the gauge speed is] an inevitable step to beat Lavos under the poor condition of my low level party. If I remained at Battle Speed 1, I would never beat Lavos. When I started making the strategy for the final battle, my Battle Speed was 5. Then I tried to advance step by step from 5 to 4, 3, 2 and 1. But I found there is a big difference for Lavos's speed between 1 and 2. when Battle Speed is 1, Lavos acts too fast to kill the left arm before Lavos uses the second doors of doom, which definitely makes it impossible to beat Lavos. If you have save data just before Lavos, compare Lavos's move interval in 1 with one in 2, and you can see how fast Lavos acts in 1. Battle Speed 2 is an absolute requirement for my low level party to beat Lavos.

[inichi later commented...] Replace some of Crono's confuse with some Ayla's Dino Tail in the Lavos Core battle. In fact, there is insane luck concerning accurate key response needed to reach the Lavos Core battle and have the center bit change the ages in the ideal order. I was so afraid to spoil the best chance of winning that I chose killing the right bit before it revives the center bit as a safe move. But, there are some times between it relieves and uses Dreamless. So here, you can replace some of Crono's Confuses with some of Ayla's Dino Tail. Fewer attacks will surely save a lot of time. Besides, Crono's second Confuse to the center bit is an unnecessary attack by my mistake. I think it is this last segment that the most improvement could be found in my run. (20-30 seconds?)
 +
 +
* '''Room for Improvement?'''
 +
 +
After reviewing the run, inichi made several notes regarding spots that could be improved to make a perfect run.
 +
 +
* Get a critical hit on the last Roly Rider in Guardia Forest (3 seconds)
 +
* Don't get a Tonic, Revive, or Heal at the Cathedral (2 seconds)
 +
* Improve fight with Yakra to best time (inichi's best is 10 seconds shorter)
 +
* Get another critical hit on the Dragon Tank battle (3 seconds)
 +
* Get a Shelter faster after that battle (1 second)
 +
* Improve transition and activities in 2300 A.D. (3 seconds)
 +
* Use the first Cyclone to more than 2 Alkalines at the Factory, which probably will enable you to kill all enemies before being attacked, and use HealBeam on Crono and Lucca only once (7 seconds)
 +
* Don't pick up a Mid Ether on the way to Heckran (2 seconds)
 +
* Defeat Zombor before the bottom portion attacks and save the game faster (6 seconds)
 +
* Run right through the enemies prior to the Masamune at Denadoro Mts (5 seconds)
 +
* Don't stop in the Forest Maze (2 seconds)
 +
* Perform luck manipulation to get EvilWeevil to dig the lower right hole faster, and don't miss saving data (15 seconds)
 +
* Improve transition from Reptite Lair to Melchior (3 seconds)
 +
* In Magus's Lair, kill enemies on the way to Flea before they attack to decrease Mid Tonic usage (5 seconds)
 +
* In Magus's Lair, complete the guillotine room faster, don't equip Frog with the Dark Mail, and don't use a Shelter (5 seconds)
 +
* Removing Frog's Dark Mail at the Dactyl's nest is no longer needed (1 second)
 +
* Don't forget to save data while fighting the 16 enemies at the Tyrano Lair (1 second)
 +
* Don't equip Marle with the Speed Belt so that a higher tech point enemy mix is preserved (2 seconds)
 +
* Don't switch Marle to Robo before the Azala battle (2 seconds)
 +
* Changing Robo and Marle in front of Enhasa is no longer needed (12-15 seconds)
 +
* Higher TP allows Ayla to learn skills without fighting three mutants in 2300 A.D. (10 seconds)
 +
* For the Retinite sequence, don't heal Marle, give her two tabs, or get stuck in the sand (8 seconds)
 +
* Give the Magic Tab to Marle before fighting Lavos's true form (-1 second)
 +
* Improve the Lavos battle with aforementioned strategies (20-30 seconds)
 +
 +
''inichi's note'': Judging from the total number, 3:32 would be possible if you don't settle for anything less through most of the run, and you might get 3:31 if the in-game clock is on your side. However, 3:30 will be impossible unless some new strategy is found.

Intro
 +
 +
I started speedrunning Chrono Trigger in preparation for Awesome Games Done Quick 2011. I'd hoped to get a submittable run soon afterward, but being a full-time mom means that I don't often get chances to attempt a 6-hour single-segment run. So it took over a year, but I finally completed this run. In a way, it's good that it took this long, because I was able to find lots of little improvements during that time.
 +
 +
This run is far from perfect; there are lots of little mistakes, as well as two big mistakes in Magus's Castle, but I was able to beat my goal time (under 6 hours real-time and under 5:45 game time), so I'm happy with it. Besides, there are other games I want to run. ;)

Shoutouts
 +
 +
Big thanks and chocolate chip cookies to the following people:
 +
 +
-Roidi, whose RTA report at Ultima Garden was the basis of my run.
 +
 +
-Nitrodon, for testing things and finding a few faster boss strategies.
 +
 +
-My brother Brossentia, for keeping me and the stream chat company during this run, and for "defeating" Atropos. ;)
 +
 +
-All the people who watched me stream this run live, for supporting me and especially for putting up with the high-pitched buzzing caused by my old TV.
 +
 +
-The entire SDA crew, for all their hard work!
 +
 +
-And of course, my husband Denton, for supporting my speedrunning, even though it usually means he has to watch the kids for the evening. :)
 +
 +
<pre><100% definition>
 +
SDA defines 100% for Chrono Trigger as completing all sidequests that Gaspar (the guy at the End of Time) mentions, which are the following:
 +
-Cyrus's ghost
 +
-Rainbow Shell
 +
-Geno Dome
 +
-Sunstone
 +
-Ozzie's Fort
 +
-Sunken Desert
 +
-Yakra XIII
 +
-Black Omen</pre>
 +
 +
Tricks used throughout the run
 +
 +
* Battle speed
 +
 +
Most of the time I keep the battle speed on 1 (fastest). However, I tested every boss battle with different speeds, and found a few where it's better to turn down the battle speed. The main benefit to doing this is having more reaction time, so I can get more turns in between the enemy's turns.
 +
 +
* Battle cursor memory
 +
 +
When the battle cursor is set to memory, it behaves a little differently for each menu. In the Item menu, the cursor will stay on whichever item you last moved it to, but in the Tech menu it won't stay on a specific tech unless you actually select that tech and target an enemy.
 +
 +
* X to attack
 +
 +
A little-known fact about this game is that during battles you can hold the X button to automatically select "Attack".
 +
 +
Running away
 +
To run away from battles quickly, hold R and L and go into either the Tech or Item menu, wait for about a second, then exit the menu. Almost every time you'll immediately escape the battle.
 +
 +
Specific comments
 +
 +
* Cathedral
 +
 +
In preparation for Yakra, I needed Lucca to have lower HP (preferably under 30), and there are two forced battles where she can take damage. The first one (Naga-ette x4) can be really random, depending on how many times they use their Slow spell instead of just attacking Lucca. This battle wasn't the best, but it could have been much worse. The second battle (Hench x3, Diablos x2) was pretty much perfect.
 +
 +
Yakra: Yakra likes to counterattack, which not only wastes time but also hurts quite a bit, but he'll only do it if all three party members are alive. It's fastest to have Lucca die as soon as possible, and Yakra obliged by attacking her first. I also got more criticals in this battle than usual.
 +
 +
* Escaping Prison
 +
 +
Things went pretty well here; most importantly, I didn't get caught by either guard. Those shield enemies are a pain to avoid, by the way.
 +
 +
Dragon Tank: The most consistent way I've found to defeat Dragon Tank is to wait for it to heal twice, have Crono attack the head 6 times and Lucca attack it once, then 3 cyclones and 2 fire whirls. Unfortunately, on Crono's 4th turn I accidentally had him attack the body instead of the head, and then proceeded to waste Lucca's next turn with attacking the head. It didn't waste much time, but it still looks ugly. Afterwards, at the bottom of the stairs normally the two guards stop you and there's a bit of dialogue, but I managed to skip all that.
 +
 +
* Lab 16
 +
 +
You can save time here by purposely running into rats; you won't get into a battle while the "Stole a tonic" message is on the screen, and there are two places in particular where you can save a few seconds by doing this. I didn't have any tonics to spare, though, so unfortunately I couldn't take advantage of this trick.
 +
 +
* Arris Dome
 +
 +
Guardian: This took longer than usual because the game was being stingy with criticals. As a side note, I only have one tonic and one revive available to use in this battle. I got into my first unintentional battle on the way out of here, and it's not even a hard one to avoid, boo.
 +
 +
* Factory
 +
 +
That first Acid should have died in 3 hits or less - seriously, Robo usually does about 6 damage. In the next battle, the ratio of Acids (orange) to Alkalines (green) is random. If you attack an Alkaline while there is at least one Acid still alive, there's a chance it will do a counterattack. I take that chance, though, if I can target a bunch of enemies with Cyclone.
 +
 +
R-Series: This is the first place I turn down the battle speed; it's needed so you can actually get a turn before they kill you. I attack the enemies in this order (front, back, back, front) to avoid their nasty "throw your character back and forth" attack.
 +
 +
* Heckran's Cave
 +
 +
I failed to avoid the Cave Bat x3 battle, which is kind of tricky to do anyway.
 +
 +
Heckran: I used to think I needed to turn the battle speed down to 2 here; the main problem was that during Heckran's second phase, Crono wouldn't get his turns quick enough to be able to heal before Heckran could possibly kill someone.
 +
 +
* Truce Canyon
 +
 +
This is the hardest battle skip in the game; I waited a few extra seconds to be sure I'd get it.
 +
 +
* Guardia Castle
 +
 +
It might not look like it, but I saved a couple seconds while talking to the chef; by running up and down, you can make some of the dialogue boxes disappear faster.
 +
 +
Zombor: It would have been nice if Crono had attacked the head more, but oh well.
 +
 +
Masamune: In the first battle, if both of them are put to sleep, it's better to attack the one of the left because he won't do anything after being woken up. In the second battle, I was lucky that the last Fire Punch actually killed him, or I would have had to deal with his counterattack
 +
 +
Nizbel: I found that if I waited to cast Lightning until right after Nizbel's first turn, for the rest of the battle I'd be able to cast Lightning right after he released electrocution energy, thereby minimizing the number of times Ayla and Robo attacked while his defense was up.
 +
 +
Afterwards in Ayla's hut, she normally stops you for a couple seconds when you try to exit; this can be avoided by talking to her and exiting while the dialogue box is still onscreen.
 +
 +
Melchior's Hut
 +
I don't really know why this works, but you can make the cutscenes here go about 5 seconds faster by continuously walking into Melchior at certain points.
 +
 +
* Truce Canyon
 +
 +
I failed the battle skip this time. :(
 +
 +
* Magus's Castle
 +
 +
Flea: I wish I better understood how this battle works. If you put the Berserker on Frog and just let him attack, sometimes Flea will get "stuck" for a while, where he just stands there and doesn't attack. In most of my previous runs I couldn't get this to happen, so I was really happy when it happened in this run. I let Robo die so Flea would stop doing The Stare.
 +
 +
Slash: Not much to say here. Crono, who deals the least damage, is the healer; Frog, who deals the most damage, is the only attacker near the end of the battle when Slash counterattacks every move.
 +
 +
The trapdoor room is the ugliest part of this run. Normally I use the pattern on the floor to avoid all the trapdoors. However, I happened to be playing on a different TV than I have in the past, and this TV was much darker and had no menu button on it, so I couldn't even change the brightness. So, since the floor looked completely black, I had to guess where to go to avoid the trapdoors, and unfortunately I guessed wrong - twice. In addition, since I'm not used to falling down, I didn't know which savepoint was the teleporter, and so I guessed wrong again. There were also a few other little mistakes: getting stuck on the second conveyor belt with the scythes, accidentally exiting a room as soon as entering it, and using Slash on the wrong enemy, so overall this is the worst section of the run. However, the Magus battle made up for all that.
 +
 +
Magus: During his first phase, Magus will change his weakness when he is hit by that weakness or when Frog has attacked him twice. I can only take advantage of lightning or fire weakness; oncee Magus's weakness is one of those, I let Frog attack once to lower Magus's magic defense before casting the spell on him. During the second phase, at full HP Crono can just barely survive Dark Matter. In the past, with really bad luck, this battle has lasted up to 16 minutes; in this run it was less than 10, which was great. In fact, I was so excited when Magus went into his second phase so quickly that I had Lucca cast Fire too soon and ended up healing him, whoops.
 +
 +
* Dactyl Nest
 +
 +
There are two battles on the second screen that are tricky to avoid, but I managed to pull both of them off.
 +
 +
* Tyrano Lair
 +
 +
I fight 7 battles here to learn Volt Bite before the next boss.
 +
 +
Nizbel II: This has been one of the hardest bosses in past runs; I had one good run attempt end here, and previous best run lost 2 minutes here because I almost died. The problem was that if I was just a little bit too slow selecting attacks, Nizbel would get too many turns and have a good chance of wiping me out before I could do the last Volt Bite. For this run I finally decided to turn the battle speed down to 2, and it definitely paid off. Also, Lucca inexplicably managed to survive this battle, which has never happened before; unfortunately, she couldn't take advantage of the extra tech points.
 +
 +
Black Tyrano: I don't heal after Tyrano's first countdown so that when he chomps my characters, he doesn't get healed as much. This allows me to be able to kill him before his second countdown ends, without having to do any extra attacks in between the two countdowns.
 +
 +
After powering up the pendant in the Zeal Kingdom, I make a slight detour to Medina to pick up a better weapon for Crono (Swallow) and a speed tab.
 +
 +
* Lab 32
 +
 +
It's about 5 seconds faster in real time to walk across the ruins, but about 30 seconds faster in-game time to do the race. (For some reason, the race doesn't count in the in-game timer). Since I'm going by SDA timing, which using in-game time, I opt to do the race again.
 +
 +
* Sewer Access
 +
 +
I love going through this place with everyone at 1 HP. ;) The only real thing of note here is that I skip the second cutscene with the frogs by simply walking to the right of the cutscene trigger.
 +
 +
Mud Imp: The most annoying boss in a speedrun, ugh. This battle can go real bad real fast, especially if Hypno Wave refuses to work on the Blue Beast. (If Hypno Wave works on both beasts, the blue one will never wake up, but the red one will.) I actually had decent luck this time.
 +
 +
* Mt. Woe
 +
 +
I need to defeat 3 Rubbles here; Ayla and Crono will learn Falcon Hit, and Lucca will be well on her way to learning Flare at the proper time. There are 4 Rubbles along my path, and if I happened to be extremely unlucky, the third Rubble respawns if you leave and re-enter the screen. (Fortunately I didn't need to do that.)
 +
 +
Giga Gaia: Turning the battle speed down allows me to defeat him before he regenerates his arms a second time, without having to do extra Napalms.
 +
 +
There are a few places in the game where if you press X at the right time, you can go into the menu when you're not supposed to be able to; just after Mt. Woe falls is one of those times. Doing this skips the scene fade-out and fade-in, which saves a few seconds.
 +
 +
* Zeal Palace
 +
 +
I have to tell the lady not to burn the plant in order to open up the Sunken Desert sidequest.
 +
 +
Dalton: Crono doesn't need anymore tech/experience points...
 +
 +
* Ocean Palace
 +
 +
I got into one battle here with Thrashers and Lashers that I should have been able to avoid. In the two rooms with Scouters where you have to press the switches, it's not that difficult to avoid fighting the Scouters once you figure out how. (The trick is to walk - not run - into the back of the Scouter.)

Golem Twins: This battle is all about timing. I want to keep them copying fire because it's their weakest attack, so I always need to do Fire2 right after Falcon Hit. I wait for both of them to attack before doing Falcon Hit so they don't manage to sneak an Iron Orb in there. In previous runs I started this battle with Lightning2, because I didn't think Lucca could cast Fire2 before one of the Golems would get a second turn, unless I turned the battle speed down. However, I found that I could keep the battle speed at 1, and if I waited a split second before choosing Crono's action, Lucca's ATB gauge would fill during his turn and she would be able to act before the Golems' second turn. (Like I said, it's all about timing.) This also allows both Crono and Ayla to use mid tonics right at the beginning of the battle, which means I most likely won't have to heal during the rest of the battle. Lucca is the only person who needs to survive here.
 +
 +
I knew it was possible to do the menu trick here, but this was the first time I'd ever managed to do it!
 +
 +
* Blackbird
 +
 +
I bring Ayla because she can fight without a weapon, and Robo and Lucca to get tech points. The only stuff I get back is my items; that way I can equip a weapon on both Lucca and Robo so they will be able to act against Dalton, and so I'll have healing items for that battle. After leaving the Blackbird, you get all the stuff except money back anyway.
 +
 +
Dalton (again): Since Dalton always counters with Iron Orb, I found that if I wait for him to attack, then have Ayla do Rock Throw, then immediately heal her, there was no possibility of Ayla dying.
 +
 +
I don't immediately put Magus in my party, because there's 5 seconds of extra dialogue between Gaspar and Magus if he's in your party at the End of Time.
 +
 +
* Millennial Fair
 +
 +
You have to have 40 silver points to get the Crono clone, so I fight Gato 3 times. Normally if you fail Norstein Bekkler's mini-game, he charges a price dependent on how long you stayed in the game. However, all my money was stolen by Dalton, so I *have* to win the game.
 +
 +
* Death Peak
 +
 +
I fight two Krakkers before the first Lavos Spawn so Robo can learn Robo Tackle.
 +
 +
Lavos Spawn 1: Fire Tackle makes this battle way too easy.
 +
 +
Lavos Spawn 2: As someone in my stream chat put it: He's so scary, he makes you want to run away!
 +
 +
I now need to fight a total of 54 Krakkers (including the two I fought earlier to learn Robo Tackle). This is so that Lucca will learn Flare at the right moment later on. Ice2 is about a second faster than Fire2, and about 2 seconds faster than Lightning2, so it's best to use Ice2 when possible.
 +
 +
Lavos Spawn 3: Since my characters have leveled up from all those Krakkers, this battle goes faster than the first Lavos Spawn - or at least, it would have if I'd thought to heal Lucca before the battle started.
 +
 +
The cutscene where Crono comes back is about 15 seconds longer if either Lucca or Marle is in the party; so I switch Lucca out of the party, but the scene just feels awkward with Robo being the one to welcome Crono back.
 +
 +
Now, onto the sidequests! The first few sidequests are done in order to get the Blue Rock and learn Flare as soon as possible, which consequently gives access to the strongest triple tech in the game: Omega Flare.
 +
 +
* Northern Ruins
 +
 +
This place has three easy forced encounters and no boss to worry about, so it's the first sidequest completed.
 +
 +
* Giant's Claw
 +
 +
The all-important Blue Rock is here, plus two Rubbles that give 100 tech points each. (I've never failed to kill the Rubbles here.)
 +
 +
Rust Tyrano: The Red Mail that I steal here will be used for Atropos and Son of Sun. I save a bit of time by timing things so that I can select Magus's attack while Crono and Ayla are performing Falcon Hit.
 +
 +
* Geno Dome
 +
 +
Every battle here is inescapable, so it's a good place to get tech points. In most of the battles, I wait a split second before selecting Magus's attack so that I can select Lucca's attack during Magus's spell animation. I'd also like to note that I hate getting that one robot to follow me. :(
 +
 +
Atropos: My brother, Brossentia, gets the credit for "defeating" this boss. In other words, he held the controller while I took a much-needed potty break. ;)
 +
 +
Lucca learns Flare right before the boss; however, even though Robo has the Blue Rock equipped, they don't actually learn the triple tech Omega Flare until you go into the menu, which is why I do so and exit immediately.
 +
 +
Mother Brain: Now you can see the overpowered attack that is Omega Flare!
 +
 +
Son of Sun: I tested many different battle speeds for this battle, and speed 3 seems to work this best. At this speed I can usually get all 10 hits in only two Roulette rounds, without the battle being unbearably slow. I made one mistake, though: I had Robo heal himself right before the second Ice2, instead of right after, so he ended up dying. At least it was near the end of the battle and didn't make much difference. (I revived him so he would get the experience and tech points.)
 +
 +
* Ozzie's Fort
 +
 +
Theres a bit of extra dialogue with Magus in the party, but since I need him for the battles here, it's not worth it to switch him out and back in.
 +
 +
Great Ozzie & Co.: Thanks to Nitrodon for this strategy. If I had simply done two Omega Flares, I would have had to sit through three counterattacks after the first Omega Flare. However, casting Dark Bomb on Flea first means that he will die after the first Omega Flare, and I'll only have one counterattack to deal with. Even though I take an extra turn with this strategy, it's still a few seconds faster.
 +
 +
I some stuff needed for the Sunstone, and then it's off to the Sunken Desert.
 +
 +
Retinite: By timing attacks so that I can select Magus's during Robo's attack animation, I'm usually able to kill the bottom part before it absorbs from the Core a second time. This makes it so I don't have to heal the Core to keep it from dying (the boss becomes much nastier if that happens). I accidentally had Magus do an extra attack at the end, oh well.
 +
 +
I now finish powering up the Sunstone, then go to do the last sidequest before Black Omen.
 +
 +
Yakra XIII: Too bad I can't use Omega Flare here. At least Marle is useful for providing defense, healing, and being a meat shield at the end.
 +
 +
There were a bunch of times in practice runs where I'd just mash A while talking to Melchior and accidentally select the Prism Dress instead of Prism Helms; that would be a run-killer, because I need the helmets to protect against status ailments in the Black Omen.
 +
 +
* Black Omen
 +
 +
It might seems strange that I didn't change their equipment until after the first battle in the Black Omen. I did this so that Magus would have the Speed Belt equipped for the Laser Guards; otherwise, the Laser Guards would get to act before he could kill them.
 +
 +
Mega Mutant: The upper part has 4600 HP, so sometimes one Omega Flare isn't quite enough to kill him.
 +
 +
I re-equip the Speed Belt on Magus and change the battle speed to 2 for most of the Black Omen; this helps minimize the number of attacks enemies get before I run away/kill them. On each elevator, you'll get between 0 and 3 inescapable battles; I got pretty lucky with these (no battles on the first elevator and only one on the second). Unfortunately, I ran into two unintentional battles: Incognito x3 and Ruminator x4.
 +
 +
Giga Mutant: Omega Flare rules! (What else do I need to say?)
 +
 +
Terra Mutant: See Giga Mutant.
 +
 +
Lavos Spawn 4: I break the "don't attack the shell" rule with my final attack, because it saves so much time.
 +
 +
Zeal 1: Zeal's first attack is always Hallation, then she does Hallation again when her HP drops below half, and then her attacks start back at the beginning so she does Hallation once again. So basically, I'm in no danger of dying in this battle.
 +
 +
Mammon Machine: Mammon Machine stands still...for Omega Flare!
 +
 +
Zeal 2: This is one of the scariest battles in a single-segment run. I can't spam Omega Flare here because the hands' counterattacks are time-consuming (not to mention dangerous). I want to keep track of Zeal's HP, because when it goes below half, she does Hallation followed by MP Buster; I need to be ready to revive anyone who might die from the hands and to use a megalixir. Then once Zeal's HP goes below 4800, I can finish her off with Omega Flare.
 +
 +
Lavos (outer shell): Most of these are pretty self-explanatory. With auto-haste on Robo, most times it's faster to use ethers during battle than in between battles.
 +
 +
Lavos (inside): My main goal at the beginning is to kill the right arm before it does Protective Seal (which removes immunity to status ailments); this is usually possible by having battle speed at 2 and using Doublevbomb for the third attack instead of Omega Flare (Magus just takes too long to get his turn).
 +
 +
Lavos Core: A perfect battle would go like this: kill the left bit with two Uzzi Punches, damage the middle bit so he'll die after two Omega Flares, wait for the right bit to lower its defense, then get in three Omega Flares before it revives the other bits; repeat, while not attacking when the right bit has its defense up; then do a single Uzzi Punch to kill the right bit. This battle can be a real pain if the middle guy decides to do anything other than Time Warp; thankfully he only did that once.
 +
 +
At the time I did this run, near the end of the battle I didn't notice the right bit turn its defense off the second time, so I felt really dumb for just sitting there waiting when I should have been attacking. However, now that I've gone back and watched the run, I've realized that the right bit never actually turned its defense back ON, which is really, really strange. So when it turned its defense off a second time, I just assumed it was turning its defense on. At least I don't feel so dumb now. :P

Hi, my name is Kari, I love playing and speedrunning RPGs, and I'm a Mormon. :)

===Running Away Quickly and Tech Selection===
 +
 +
''Discovered by inichi''
 +
 +
This enables you to quickly run away from the escapable battles. When the battle begins, hold the L and R buttons, push the A button on tech or item command and push the B button. Then the moment you push B button, you can run away from the battle. By using this technique, I succeeded in running through the four battles in Magus's Lair without receiving any attacks. It saved a lot of time. There's another reason to do this -- to prepare for the next battle by selecting the tech I'm going to use beforehand. For example, I select Cyclone, which is used in the first battle in Tyrano Lair, in the battle in Dactyl's nest before running away. And I select Haste just before Retinite dies because the next tech Marle uses is Haste in the Lavos battle. There are a lot of places I did the same thing in my video.
 +
 +
===Delaying the Cotton Candy Scene===
 +
 +
''Discovered by hero of the day''
 +
 +
Due to the way Chrono Trigger handles PC detection, it is possible to reach the exit leading to the Telepod sequence without being stopped by Marle for cotton candy. However, the scene cannot be avoided when returning to the overworld, even after playing through the 600 A.D. Queen Leene / Cathedral sequence.

'''Tricks and glitches'''
 +
 +
Loading corrupted save data
 +
 +
The game writes hash checksums upon saving; if the checksums don't match, the save(s) will be unloadable and displayed as empty.
 +
 +
Howewer, due to an oversight, it is possible to bypass this check and load corrupted save data by pressing Up+A on the save load screen.
 +
 +
'''Detailed commentary'''
 +
 +
'''Millennia Fair'''
 +
 +
Marle is picked up. If the Imp's house is entered without her in the party, the game will crash.
 +
 +
'''Zenan Bridge R1'''
 +
The game is saved twice to set up save corruption at a later time.
 +
 +
'''Guardia Continent, Eastern Nebula'''
 +
 +
The position value 1F3E is partially overwritten with the party's current position, 4A50, resulting in the position 4A3E being stored in SRAM.
 +
 +
'''Guardia Continent, Imp's House'''
 +
If Marle isn't in the party when entering this area, the game will crash.
 +
 +
'''The End of Time'''
 +
 +
The game is saved on a save point, resulting in the corresponding flag being set in SRAM. The subframe reset here is just for show - allowing the save to complete would yield equivalent results.
 +
 +
'''Zenan Bridge R2'''
 +
 +
The Zenan Bridge save is loaded. The game is then saved over the End of Time save and interrupted after the location values are written but before the save point flag is removed. This allows us to save anywhere.
 +
 +
'''Zenan Bridge R3'''
 +
 +
The game is saved on Zenan Bridge, resulting in a save file with a location value of 2000. We then exit the area and reset while the location value F001 is being written to the save file, resulting in SRAM containing the location F000.
 +
 +
'''Nu Ending'''
 +
 +
The location value F000 corresponds to the Nu ending, so the run ends when the save is loaded. Since triggering the ending in this manner wasn't intended, glitched graphics are briefly shown.
 +
 +

About obsoletions
 +
The published any% and NG+ movies both abuse save corruption. This run is faster than both; obsoleting both of them seems to make the most sense.

Finally, I made it. I'm sorry for keeping the entire movie-making process secret and not posting any WIP on the forum. The expected improvement was so gigantic that I couldn't resist an inpulse to make the run surprising. Also, the submission text is still incomplete. I think this is a bad thing. However, considering these facts:
 +
 +
* Most part of the run is totally new stuff. So it would take a long time to cover them all, even in Japanese, my native language.
 +
* This is a long-term project; I started making the run in August 2007.
 +
* Chrono Trigger is a very popular RPG, and not a few people have been interested in how the run is going.
 +
 +
I thought it would be better to submit the run as fast as I could than to write up full texts and submit it. I will upload the rest of the submission texts little by little.

'''About the game'''
 +
 +
Chrono Trigger is a memorable role-playing game developed and published by Square in 1995. The story is about a boy named Crono who travels through time with his friends to save the world from an alien parasite, Lavos. The game is also recognized as one of the best RPG, attracting a lot of new fans even today.
 +
 +
'''About the movie'''
 +
 +
This is a 3 hour 59 minute 48 second improvement over Hero of the Day's [http://tasvideos.org/923S.html current published run]. The improvement mostly came from massive new tricks and glitches. See the below "Tricks and Glitches" section for details.
 +
 +
'''Tricks and Glitches'''
 +
 +
In this section, I will give a full explanation of all glitches and tricks I used in the run.
 +
 +
'''Item duplication'''
 +
 +
This is a glitch to duplicate items by loading a corrupted save file.
 +
 +
Mechanics: It takes 2 frames to save the game in Chrono Trigger. some values between 7E2400 and 7E264F are overwritten in SRAM in order in the first frame; the rest of them and values in addresses after 7E264F are overwritten in order in the second frame. That means you can get a half-saved save file if you reset the game in the first frame of saving. Off course, this is an invalid procedure for the game, so the target data is deleted. In Chrono Trigger, however, you can load the corrupted data by pressing A and up/down key at the same time in the load screen.
 +
 +
Also, for the reason mentioned above, you can only affects on 7E2400-264F by resetting in saving. What are in those memory addresses are like this:
 +
 +
* 7E2400-FF: Item ID (last 14 bytes are unused).
 +
* 7E2500-FF: Item number (last 14 bytes are unused).
 +
* 7E2600-4F: Crono's status
 +
 +
How many addresses between 7E2400-264F are overwritten in the first frame are slightly influenced on the previous key presses and cursor movements. Basically, you can manipulate it to some extent by changing them or costing a few frames. To make things easier, I used a lua script.
 +
 +
How to duplicate an item? Item duplications are basically classified into three methods. I'll explain for each method.
 +
 +
Explanation of the chart: Using data is a data that you use to save. Object data is a data that are saved in the glitch-use. Result data is a data you get after the glitch-use. Bronze means Bronze Helm; Hide means Hide Cap. Null means there are no items in the slot. Numbers next to them means item number.
 +
 +
Method 1:
 +
 +
<pre>Using data Object data Result data
 +
Null 0 Null 0 Null 0
 +
Null 0 Null 0 Null 0
 +
Bronze 2 Hide 1 Bronze 1
 +
Hide 1 Bronze 2 Hide 2</pre>
 +
 +
This method is kind of switching. Only item ID is overwritten, and you can get two items with different ID. This is done in one reset.
 +
 +
<pre>Method 2:
 +
Using data Object data Result data
 +
Null 0 Null 0 Null 0
 +
Null 0 Null 0 Null 0
 +
Bronze 2 Hide 1 Bronze 1
 +
Hide 1 Bronze 2 Bronze 2</pre>
 +
 +
This method is basically the same with the first one except that the below item ID isn't overwritten. As a result, you can get the same items that have different numbers. This requires extreme precision, unless you insert some null slots around the border, which is slower. This is also done in one reset.
 +
 +
<pre>Method 3:
 +
 +
Phase 1:
 +
 +
Using data Object data Result data
 +
Hide 1 Null 0 Hide 1
 +
Bronze 2 Null 0 Bronze 2
 +
Null 0 Hide 1 Null 1
 +
Null 0 Bronze 2 Null 2
 +
 +
Phase2:
 +
 +
Using data Object data Result data
 +
Null 0 Hide 1 Null 1
 +
Null 0 Bronze 2 Null 2
 +
Hide 1 Null 1 Hide 1
 +
Bronze 2 Null 2 Bronze 2
 +
 +
Phase3:
 +
 +
Using data Object data Result data
 +
Hide 1 Null 1 Hide 1
 +
Bronze 2 Null 2 Bronze 2
 +
Null 0 Hide 1 Hide 1
 +
Null 0 Bronze 2 Bronze 2</pre>
 +
 +
This method is the most complicated, but most powerful one of all. With this method, you can extend items over the above null slots. This actually can be done with Method 2. However, it is much slower because it requires you to buy other items for replacement in each use, which takes much time. This method also requires extraordinary precision, unless you insert some null slots around the border, which is slower. You need to reset three times for this method.
 +
 +
How they were used in the run? Duplicating Hide Caps and Bronze Helms and having them in 98 slots with three methods. This is what I did in the first 3.5 minutes in the run. I'll write it down step by step:
 +
 +
First, I bought 1 revive and 20 Tonics from the merchant at the fair for 400G, Crono's pocket money. With Method 1, Two items ID were switched, resulting in 20 Revives and 1 Tonic, both of which were immediately sold. With that money, I bought a Bronze Helm and 5 other items from two merchants. Second, with Method 2, I changed 5 items into Bronze Helms and Hide Caps. Now I had Bronze Helms and Hide Caps in 7 slots. Finally, with Method 3, I extended them over the above null slots. The actual pace is like this: 7-13-25-49-98. Thus, I got Hide Caps and Bronze Helms in 98 slots.
 +
 +
Having the same type of equipment in 98 slots allows you to access various memory addresses via the equipment screen in Chrono trigger. This is actually the only purpose of all item duplications I did in the first 3.5 minutes. I'll explain the detail in the below section.
 +
 +
'''Accessing various memory addresses.'''
 +
 +
As stated above, Having same type of equipment in 98 slots allows you to access various memory addresses that you normally can't.
 +
 +
Mechanics: When you call on the individual equipment screen, item ID that corresponds the equipment type that the cursor currently points out is stored in 7E0F00-60; item number in 7E0F61-C2 as well. All they appear in the equipment selection screen. Yes, as you can see, each has only 96 bytes for their purpose. So if you have the same type of equipment in more than 96 slots, item numbers will flow into 7E0FC3 or later addresses. It is required to flow them into 7E0FC4-6 to access various memory addresses. This is why you need to have them in 98 slots at least. I write down the function of those addresses:
 +
 +
*7E0FC4: Decides how many the cursor can move in the character selection screen.
 +
*7E0FC5: Decides where the cursor is in the equipment screen. It also works as an offset when you equip, which is stored in C2A4AB-A5AA, and it works like this: 7E2600+xx (in Crono's case)
 +
*7E0FC6: Decides how many the cursor can move in the equipment selection screen.
 +
 +
In my run, I accessed and overwrote these three addresses: 7E2985, 7E2980 and 7E2990.
 +
 +
**7E2985: An address for a third reserve character. You cannot access 7E2983-84 because any appropriate address doesn't have 13-15, 63-65, B3-B5. I stored 0A in 7E2985, which saved a lot of time when accessing 7E2980. Also, although the address is for a third character, it is treated as it is just under the main three characters when no one is in the first or second reserve.
 +
*7E2980: An address for the first party character. You can't access 7E2981-82 since any appropriate address doesn't have 11,12,61,62 B1, and B2. This was rather inconvenient, but not much. This address was heavily accessed and overwritten throughout the run to call out a character who must be in a cutscene or to use "Character warping" trick that will be picked up later.
 +
*7E2990: An address for the configuration setting. By modifying the configuration setting, you can store any value out of 256 in the address. Because you are accessing it via the equipment screen, if you equip something with it, the value in the address appears as an item in the item inventory. The thing is, you can retrieve any item from this address.
 +
 +
The alternative way to retrieve an item is to use an address of one character of name strings. The problem with that plan is, once you retrieve an item from it, you can't use the character for that purpose again. I needed three different items in the run, Bike Key, Elixir and Green Dream. That means I have to change the item order twice to withdraw an item from another character, which would consume time.
 +
 +
'''Character warping'''
 +
 +
Every time you open the pause menu, all your three character X-Y coordinates are stored in proper addresses. However, if a missing number is in your party and he is not in the first, the appropriate address is not updated. And then, if you replace the missing number with a normal character, the character appears on the coordinates which was stored in when you previously opened the menu. Now a second or third character warping happens. After you use the warping trick at least once in an area, coordinates stored in the addresses always take the same value with a normal character one even if a missing number is in your party. Therefore, you can make even the first character warp by keeping the missing number in the party in the first warp, and just replacing him with a normal character.
 +
 +
Very unfortunately, this isn't applied to overworld coordinates. If it was feasible, the run would shrink by another 10 minutes.
 +
 +
'''Character sliding'''
 +
 +
Normally, a second and third character mimic the first character's movement. However, if he is a missing number, he can't mimic the first. Instead, the movement he should have mimicked stacks up in proper addresses until a counter reachs 128 and erases them all. With enough such stacks, if you replace a normal character with the missing number, the character starts sliding, mimicking the movement that has stacked up. While sliding, the character can go through any obstacles.
 +
 +
To make the most of this, you need to use the character warping once or change a character order beforehand so that missing number's next X-Y coordinates could be subject to the normal character's one. Otherwise, a character called out will warp far away and start sliding there, which is unfavorable.
 +
 +
'''Marle join skip'''
 +
 +
If you talk to either one of the two merchants with Marle in the party, he sets a flag to remove the men who block the way to Telepod area. Thus, you can entirely skip the marle joining cutscene and enter Telepod area.
 +
 +
Alternatively, you can go through those men in the same way as used in the Factory, which will be mentioned in the below section. When you go back from Telepod area, however, they block your path, and you have to go through them again. So it's a waste of time, though it might be useful for a new game+ run.
 +
 +
'''Pause menu abuse'''
 +
 +
By opening the pause menu and leaving it when the screen starts to fade out, you can have a few frames to move in another direct. If you repeat this again and again, you can get to a point that would trigger a certain event, keeping the fade-out status. If you set a flag that determines if the event completed and let the fade-out be done, you are brought to the previous room and it is considered the event already finished.
 +
 +
This trick could have been featured as a main timesaver to skip some boss battles. However, due to the discovery of the more sequence-break glitch, the trick was used in only one place moderately: Telepod area, to skip Lucca’s dialogue.
 +
 +
'''Playing around at the Telepod area'''
 +
 +
Unless Crono picks up the pendant, you never lose control, which provides a first huge play-around time. This is useful not only to mess around, but also to make a moving counter of Taban and Lucca faster. Normally, the moving counter of them are incremented by 1 per 4 frames. However, if you keep touching him/her, it is incremented by 1 per 1 frame. Also this is a necessary step to completely skip Middle Ages. See the below section for details.
 +
 +
'''Middle Ages skip'''
 +
 +
In every gate transition, a flag that determines if you are in warping is set a few frames before the fade-out completes. That is, you can escape the area with the flag is on if you interrupt another fade-out, which was the entrance of Telepod area in my run's case. If you enter the gate area with the flag is on, the game considers you just got through the gate, and consequently open the gate with your character. In Telepod area's case, the game also considers you just returned from Middle Ages, and increments the storyline counter enough to trigger the trial events. A big timesaver, certainly. Also, Marle must be in the party when you enter the castle; otherwise the game freezes right after entering the castle.
 +
 +
Alternatively, I tested to go to Guardia Forest gate area instead of entering the Telepod area right soon, hoping to entirely skip the trial cutscene. As expected, Magus appeared from the gate; however, the gate disappeared soon and I wasn't able to go into it, proving it not useful for the run.
 +
 +
'''Candy skip'''
 +
 +
A flag that triggers the candy cutscene is set when Marle joins in Crono. Since Crono and Marle never met in a intended way in the run, the candy cutscene also never happened.
 +
 +
'''Getting out of the trial'''
 +
 +
In the flashback scene of the trial, the game makes the first character appear there. And if the first character isn't Crono, you can move him at free. If he is a missing number, nobody shows up there, but you can still open the menu. And then, if you call out a normal character, it meets the condition of "Character warping trick" and he appears in the same position with where you previously opened the menu.　In my run, it is the south entrance of Leene’s Bell area. At this point, the storyline counter is enough to trigger the Marle runaway cutscene. Thus, you can skip the latter half of the trial and all the events in the jail. A huge time-saver, off course.
 +
 +
Also, Lucca must be in the party when you enter the castle; otherwise the game freezes after Marle runs out of the castle.
 +
 +
'''Arris Dome skip'''
 +
 +
Johnny appears at Lab 32 if you enter there with a Bike Key. That means you can completely skip Arris Dome, where you can get a Bike key from Doan after you finish all the events there. This may be not intense, but definitely a solid timesaver.
 +
 +
'''Bike Race skip'''
 +
 +
This is very similar to Middle Ages skip. A flag that determines if the race was over is set a few frames before a fade-out to the race track completes. Also, the fade-out is slower than the usual screen transition one. The thing is, if you start a fade-out to overworld just after you turn the key, you can escape to the overworld with the flag is set. "Character warping trick" only makes it possible, so you need a set up beforehand. I used a north edge of Lab 16 east for that purpose because it has the same Y coordinate with the south entrance of Lab 32. You may notice I did a strange behavior in Lab 16 east. That is exactly the set up for Bike Race skip.
 +
 +
Alternatively, you can directly get the needed Y coordinate at the south entrance of Lab 32. However, it requires to go out and in Lab 32 to avoid the freeze that results from the lack of characters. After all, it will be slower.
 +
 +
'''Warping to the main area of Lab 32'''
 +
 +
Once that flag is set, the entrance to the Lab 32 main area is activated. In Chrono trigger, most entrance never causes the fading out unless you move in there. That entrance, however, doesn't require such movement, and lets you go into the next area by just standing there. If you enter any location followed by a missing number, the game considers you are at (255,0), the right above place, which is in the entrance of Lab 32 main area. So the game immediately sends you into the main area.
 +
 +
There is another reason I had to use this trick: If you enter there followed by a normal character, Johnny tries to speak, but since he is outside the screen, he can't do it and the game freezes. Using this trick is the only way to avoid the freeze and advance the game.
 +
 +
'''Going through the barrier sprite'''
 +
 +
You can vertically go through the barrier sprite if it is outside the screen. To achieve this, you have to enter the room with a missing number in the first character. By this, the game considers you at (255,0) and then focus the camera on that point, which allows you to go through the barrier.
 +
 +
Alternatively, you can go through the barrier by using "Character sliding" trick instead. However, it requires one extra menu-opening, so I didn't use it, though I had no choice to use it when trapped out. Because this time it was required to move horizontally to go through the barrier.
 +
 +
'''Playing around with R-series'''
 +
 +
R-series bounce off only Crono. That means you can move around during the cutscene by fitting other character in the first, providing a second huge play-around time. It should be noted that Marle and Lucca won't do because they will take their regular position and just stand still. Like the Telepod area, this free-time is useful for shaving off frames. I did these two things for that purpose: 1) Erase the dialogue screen of R-series or Robo before they pop up by getting them out of the screen at the right timing. 2) Increments the moving counter of R-series by touching one of them at certain timing.
 +
 +
Normally, after Robo is knocked down, you become unable to move a character anymore. However, if you interrupt a fight with Alkalines just before losing control, R-series are also caught in the battle. This was supposed to be the fight with only Alkalines, so you can escape from them. Thus, you can gain control again. When the real R-series battle is about to start is the best timing you interrupt another Alkalines battle. With this, you can not only escape from them again, but also increments the storyline counter enough to open the door in Proto Dome.
 +
 +
'''Smoothly escaping'''
 +
 +
An escape counter builds up even when you open the technique or item menu in battle. The thing is, you can escape from a battle without being attacked by setting the battle mode "Wait", opening the either menu and holding the L+R buttons. This trick was featured in all the three battles in the Factory.
 +
 +
'''Robo repair skip'''
 +
 +
If you enter Proto Dome from overworld after the R-series fight, the game considers you just dragged Robo into, and make characters appear in front of the door for repair. That area is actually in warning area of the below enmies, so the characters start running down for fighting, though a fight starts halfway. When the fight finishes, you gain control and the repair cutscene never starts. At this point, the door to the gate room already opens; consequently, you can completely skip the Robo repair cutscene.
 +
 +
Also, when you enter Proto Dome, the first character must be Crono for these two reasons: 1) If you enter the gate room without Crono, the game freezes. 2) If a character is other than Crono, Marle, Lucca and Robo, he/she appears near the entrance, which doesn't awake the enmies and the game freezes.
 +
 +
'''Playing around at the End of Time'''
 +
 +
When you speak to snoring Gasper, you are given a few frames to move around until he starts talking. And if you take the opportunity of talking to Robo twice, you can avoid losing control. This is actually temporary, and you will lose control as usual after you skip the dialogue. However, if you check the healing bucket right after skipping the dialogue, three party characters get together and you can gain control again, providing a third huge play-around time. In the non-glitched run, the trick saves little time, only allowing you to get slightly faster to the point that Gasper shouts "Hey!" to Crono. In the glitched run, however, the trick serves as the set up to perform "Lavos Shell skip" more smoothly and dramatically. I'll pick it up later.
 +
 +
'''Confusing Spekkio'''
 +
 +
If you talk to Spekkio while you are still running around the room, he claims to do it over. However, if you continue and complete it keeping the dialogue screen open, he thinks it as succeeded. This doesn't save any frames, but I added it to the run because I felt it would slightly enhance the entertainment value.
 +
 +
'''Lavos Shell skip'''
 +
 +
This trick makes full use of the characteristics of gate transition as well as Middle Ages skip does. This is definitely the most difficult trick to pull off. Here are some important facts:
 +
 +
# In every gate transition, your starting X-Y coordinates in the next location is set a few frames before a fade-out completes.
 +
# If you open the menu in that tiny window, you can overwrite them with the current X-Y coordinates.
 +
# If your characters appear at (7-8, 0-8), the entrance into Lavos's body, in the day of Lavos, they immediately jump into Lavos's body. The reason is that the entrance has the same features as the Lab 32 one: Fade-out occurs by just being at the appropriate position.
 +
 +
The thing is, if you manage to open the menu at (7-8, 0-8) at the End of Time just before the fade-out to the day of Lavos completes, you can completely skip Shell Lavos. Normally, this is out of the question. In the first place, (7-8, 0-8) is outside the moveable area. Second, you lose control right after checking the bucket to the day of Lavos, which means you can neither move nor open the menu anymore. To solve this problem, I used the following glitches:
 +
 +
# If you run around the End of Time autofiring the A button with a dialogue screen opened, the second and third character eventually fall behind the first.
 +
# If the two are too far behind the first, they stop catching up with the first and newly start it with reference to the position they stopped. Note: You need to use the trick "Playing around at the End of Time" to reproduce these two glitches in a timely manner.
 +
# Hold two gate messages, choose yes for each. Then if the second message screen closes just before the rest characters, who run at the first to fly for the first gate waping, joins in him, you can restore the function to open the menu even while flying.
 +
# Under these conditions, if you change the order of characters twice, you can get out of flying and freely move.
 +
 +
To pull off these four glitches are required to skip Shell Lavos. Here is what I did in the run:
 +
 +
First, use the "Playing around" trick and get the other characters out of the screen with the first and second glitch while Gasper gives the long speech. Second, replace the three characters with Ayla, Magus and $17 when Gasper finishes the speech. The reason I call out Magus and Ayla is they don't take any action when Spekkio tries to give Magic, which saves a few hundred frames. Although it's not visible, Lucca, the third character, is at (8,0) at this point. These coordinates values are stored in the proper addresses, which will be really helpful later. Third, enter Spekkio's room and acquire Magic from Spekkio, no one actually gets it though. Now the bucket to the day of Lavos is activated. Fourth, check the bucket so that the Gasper's warning message doesn't hinder the third and fourth glitches.
 +
 +
Fifth, talk to Gasper because it is needed to show his dialogue to hold more than one gate message. Sixth, hold the Proto gate message, which is the shortest one of the three, and check the bucket. Seventh, use the third and fourth glitches and get right to the save point. Since the Lavos gate message was the first, warping to the day of Lavos is going to occur at this point. It should be noted that (8,0) is still stored in the addresses because only the first and second character were swithced. Eighth, right after the starting X-Y coordinates in the day of Lavos is loaded, use the character warp trick, send the first character into (8,0) and save the game. The save point effect lasts for a few frames after you leave there, so that's no problem to save on that position. Now the save file includes the day of Lavos as the current location, and (8,0) as the current position. Finally, reset the game and load the save file. Magus appears at (8,0) in the day of Lavos. As I stated above, that position is in the entrance to Lavos's body. Therefore, the game sends him into the inner body in a blink.
 +
 +
Now we've done Lavos Shell skip!
 +
 +
It is extremely difficult to pull off, but the result is priceless. For the record, this is my favorite trick of all I have discovered.
 +
 +
'''Instant kill'''
 +
 +
Normally, when a character with the Green Dream is defeated, he automatically revives. However, when two RNG conditions are satisfied, the game temporarily considers him as dead. and if the other two characters are really dead at that point, he becomes unable to use an item on enemies instead of himself. If you use an Elixir on an enemy and the sum of its current HP and the HP heal is more than 32768(0x8000), that causes overflow and does instant kill. Inner Lavos has 20000 HP; Lavos Core has 30000 HP. Therefore, you can immediately finish those battles with the glitch. This is why I had to get a Green Dream and an Elixer from the configuration setting address.
 +
 +
Also, for some reason, the glitch never occurs if the character has any status effect such as protect or chaos on him/her. I guess this is why the trick had not discovered for a long time.
 +
 +
'''Useful key combinations'''
 +
 +
There are three useful key combinations to be mentioned:
 +
 +
X: If you press the X button in battle, you can point at an enemy as an attack target wherever the cursor is. This was helpful for targeting Lavos in using the instant kill glitch.
 +
 +
Start and Up/Down/L/R: Normally, you need 2 frames to move the cursor, as you have to insert null frame in each key press. However, if you press either the Up or Down key holding the start key, the cursor moves per one frame, which makes it possible very rapid cursor movements. The same goes for the L/R buttons. It normally requires 5 frames to scroll three pages; however, holding the start key reduces it to 4 frames. It should be noted, however, that it can be applied in only three places: the item inventory, the equipment selection screen, and the shopping window. In battle, for example, holding the start button will do nothing. This really comes in handy in a save-corruption run because you have to move up and down in the item inventory multiple times to perform the item duplication glitch properly.
 +
 +
B and Start: Once these two buttons are pressed in the pause menu or the character change menu, every frame is treated as the B button pressed until you leave the menu. Thus, you can immediately get out of the menu no matter where you are. Note that this is slightly faster than the normal method because it requires null frame in each B button presses.

'''About the movie'''
 +
 +
This is my second attempt at Chrono Trigger New Game+ run. It is 8661 frames (2 minutes and 24.35 seconds) faster than [http://tasvideos.org/1664S.html the previous one]. The improvements came mostly from a new glitch that allows all characters to equip a Bronze Fist, but other minor timesaver was also found.
 +
 +
'''About the version change'''
 +
 +
I switched to the Japanese version because the glitch in the English version, unlike that in the Japanese version, doesn't allow any characters to equip a Bronze Fist. Bronze Fist deals 9999 damage on a critical hit regardless of enemy's defense. This means that there would be a significant delay on each boss fight in the English version. Even considering benefits from Japanese faster texts and taking them all away, the Japanese version will still be at least 1.5 minutes faster than the English version. More details about the glitch can be seen in the new tricks section.
 +
 +
'''About SRAM'''
 +
 +
In the previous run, I used Saturn's maxed-out save file that had been validated. This time, however, I needed to use my own save file because I decided to switch to the Japanese version as stated above. To clarify, I recorded the whole [http://www.mediafire.com/?aiiaiiaaaig setting up process], starting from clear SRAM. I believe it would work as a good reference and verify the validity of the run.
 +
 +
'''New Tricks'''
 +
 +
In this section, I will describe new tricks I used in making the run. It should be noted, however, that all these tricks will not show up in the movie. They were performed only in the setting up process.
 +
 +
'''Loading a save file that shows "No Data"'''
 +
 +
By pressing A+Up/Down at the same time on the load screen, you can access a save file that says "No Data". Depending on SRAM conditions and the data selection mode, the following three cases are possible. If you use the trick:
 +
 +
* Against a clear save file on the normal mode, the screen will black out and never recover.
 +
* Against a dirty save file on the normal mode or the new game+ mode, the previous save file will be loaded.
 +
* Against a clear save file on the new game+ mode, abnormal values will be loaded, and a new game+ will start.
 +
 +
The first is obviously useless. It may seem the second isn't of any use, but it was actually really important for the run, which will be taken up later. The third is the core of the trick; let us go into detail.
 +
 +
As with many other SNES games, at first 96 is stored in all SRAMs in Chrono Trigger. In the third case, 96 is stored in various memory addresses such as for the item inventory and character's stats, and then a new game+ starts. Naturally, that causes many strange things to the game, which is "the glitch" that I have called. I will list some glitch features that are strongly related to the run：
 +
 +
* Every character can equip any equipment except for two kind of weapons.
 +
 +
There are important differences on equippable weapons between the (U) ROM and the (J) ROM (see list below).
 +
 +
<pre> equippable non-equippable
 +
(U) Bow, Gun, Broadsword, Arm, Scythe Sword, Fist
 +
(J) Sword, Gun, Broadsword, Fist, Scythe Bow, Arm</pre>
 +
 +
As seen in the list, Fist type weapons, including Bronze Fist, are equippable only in the (J) ROM.
 +
 +
* Almost all stats for every character are 96.
 +
 +
The only exceptions are speed, HP and MP. Speed is 16 because that is the limit value; HP and MP are 24672 because they are given two bytes. This feature makes it possible to get almost maxed-out stats for all characters without using any tabs.
 +
 +
* Every character's techniques are limited.
 +
 +
Every character is allowed to use only the 2nd and 3rd single and dual techs. You can retrieve the 1st single tech of Crono, Marle, Lucca and Frog by having them meet Spekkio. However, there is no way to learn any other techs, since no enemies won't give Tech Points in a glitched data anymore.
 +
 +
* A great deal of lag occurs during a battle.
 +
 +
Roughly estimated, the lag will make a battle 30% slower than a comparable battle in a normal data. Fortunately, that kind of lag can be completely avoided by keeping the item screen open.
 +
 +
* Ayla's Bronze Fist doesn't appear.
 +
 +
Ayla's special ability, which automatically equips certain kind of fist depending on her level, is lost forever. Ayla's level is 96 in this case, so she should have a Bronze Fist, but the glitch doesn't allow it.
 +
 +
'''De-equip trick'''
 +
 +
In Chrono Trigger, you can change equipment, but cannot unequip it except when you are on the Blackbird. However, De-equip trick lets you do it anytime if certain conditions are met.
 +
 +
'''Requirement:'''
 +
 +
* No equipment that the target character can change are in the item inventory.
 +
** To give an example, if you want to unequip Crono's Armor, you must sell out every armor that he can equip.
 +
 +
'''How to:'''
 +
 +
# Press L+down or R+up simultaneously on the equipment screen, and the previous character's equipment will be remained on the left screen. (It is required the cursor doesn't loop back in the key presses (by "the cursor doesn't loop back", I mean the cursor doesn't jump from the first character to the last and vice versa or from the weapon grid, which is located on the top, to the Accessory, which is located on the bottom and vice versa).)
 +
# Press A, and a blank space will be called to the left.
 +
# Press A again, and you can equip the character with "null"―unequip the character's equipment.
 +
 +
On a related note, the trick also has useful features other than the mere de-equip stuff. However, I won't go into further since it is not important for the new game+ TAS at all. For those who are interested in, check out [http://tasvideos.org/forum/viewtopic.php?p=165616&highlight=#165616 this post].
 +
 +
'''Transferring items from one data to the other'''
 +
 +
If you reset the game one frame after you save a data, only SRAM for the item inventory and Crono's status is overwritten. As a result of reseting the game in the middle of save processing, a target data shows "No Data". However, as it turned out, now that you can restore a deleted data with the data selection trick, there is no problem.
 +
 +
'''Notes on SRAM overwritten:'''
 +
 +
* Item ID is almost always overwritten; item number is overwritten only if the trick is used against a dirty save file. That means you can duplicate all items to 96 by using the trick against a clear save file.
 +
* Apparently Crono's status has a 70-80% chance of being overwritten.
 +
 +
'''Performing the tricks'''
 +
 +
So far I have discussed the new tricks. In this section, I will focus on how they were combined and performed in the setting up run.
 +
 +
First, I unequipped Ayla's Bronze Fist with de-equip trick on a normal data. Second, I transferred it to a clear save file. Luck was manipulated so that Crono's status wouldn't be overwritten, leading to only Item ID overwriting and item duplication. Finally, I pulled off the glitch, using Data selection trick (you might think the save file is not entirely clear at this point, but overwriting only item ID doesn't affect the glitch performance).
 +
 +
Thus I got the glitched save file in which has Bronze Fists, which can be seen at the beginning of the run. For possible reference, I will provide a demonstration movie, showcasing all the three tricks in a short length.
 +
 +
Note: Make sure that your Snes9x 1.51 is 5 or newer version before playing the movie; otherwise, the trick won't be reproduced properly and it will desync in the end.
 +
 +
'''Detailed commentary on the movie'''
 +
 +
In this section, I will give a full description on the movie place by place, especially for different parts from the previous run. Note, however, that I didn't pick up any frame gain/lose from:
 +
 +
*Loading scene. This is highly rely on what emulator and ROM you are using. Since I used the different emulator and ROM from the previous run, it was very difficult to tell which was influencing on this. For ease of comparison, I decided to let it untouched.
 +
 +
*Text scene. All through the run, Japanese faster texts were helpful in saving a frame. However, I didn't think that kind of improvement was a real one because it was done without putting any effort in, hence I excluded them from counting. For reference, I suppose the text differences would be around 1000 frames in total.
 +
 +
'''Load Screen'''
 +
 +
The only way to change a critical hit RNG in the first battle is to load a save file on a different timing. I load the save file 55 frames late. This is a huge delay, but there is no RNG that will make a critical hit happen on the best timing in every three battles before that timing. 50 frames lost (I had already delayed it by 5 frames in the previous run).
 +
 +
'''Battle mode screen'''
 +
I select Active. As I mentioned in the tricks section, you can reduce lag with the item screen opened. Wait is not suitable for this purpose, because it prevents the active bar from building up too.
 +
 +
'''Crono's name screen'''
 +
 +
I give Crono one-character name. The initial reason is that this is the Japanese version, and it was expected that most people here wouldn't care what he would be called in Japanese. I believe it wouldn't sacrifice any entertainment value. Since "Crono" is composed of three characters in Japanese, 2 frames will be cut off every time his name is called. 5 frames lost (but it will pay off little by little).
 +
 +
'''Lucca's name screen'''
 +
I keep Lucca's name as it is. Shortening her name doesn't save any frame because it will appear only twice in the run.
 +
 +
'''Leene Square'''
 +
 +
Put Crono in a better position when returning the pendant to Marle. 2 frames saved.
 +
 +
'''Marle's name screen'''
 +
 +
For the same reason as Crono, I give Marle single character name. 5 frames lost (but it will be rewarded eventually).
 +
 +
'''Shop screen'''
 +
 +
As usual, this is a good chance to change equipment with slight delay. Here are all equipment I give Crono and Marle:
 +
 +
# Bronze Fists to Crono and Marle to deal 9999 damage.
 +
# Haste Helms to Crono and Marle to double their speed.
 +
# A Berserker to Crono to get the best critical hit RNG at the end of Lavos Shell battle.
 +
 +
The first two will be self-explanatory; the last may sound a bit strange. In the Lavos Shell battle section, I will take it up in detail. 6 frames gained by less equipment change. 1 frame gained by pressing Up instead of B in getting out of the shop, eliminating a null frame. In total, 7 frames saved.\
 +
 +
'''Leene Square'''
 +
 +
Change the timing of entering into the area that sets the Candy cutscene, which allows you to pass the area without stopping. 5 frames saved.
 +
 +
'''Before Lavos Shell battle'''
 +
 +
Menu Entrance trick is used to change the battle speed to 2. That must be 2 because you cannot attack twice preceding the Hand Sickles of Inner Lavos at highest speed. In the previous run, I needed to set the menu cursor remaining function to reduce the amount of cursor movement. This time, however, I don't have to change anything except for the battle speed. 2 frames saved.
 +
 +
'''Lavos Shell battle'''
 +
 +
Weapon attack always increments the critical hit RNG for the next battle by 2; Berserker has additional increment before that process, which is depending on what an existing enemy's ID is. This additional increase is necessary to get the two critical hits in the Inner Lavos battle. This is why I gave the Berserker to Crono at the shop. Rapid cursor movement doesn't generate any lag in the battle, but affects the duration of screen transition. I will take it up in possible improvements section again. 1121 frames saved.

 +
<pre>Character Attack Type Damage Total Damage Note
 +
Crono Normal hit 390 390 Lavos Shell has 10000 HP.
 +
Crono Critical hit 9999 10389 Fatal.</pre>
 +
 +
In the planning phase, I tried an alternative strategy:
 +
 +
*Equip Marle with a Berserker as well. Marle's shot has shorter animation than Crono's critical hit. If it were done on a normal data, it would definitely be faster. In a glitched data, however, you cannot prevent lag from occurring with the item screen opend anymore. Because lag is too much, it would be slower in the end.
 +
 +
'''After Lavos Shell battle'''
 +
 +
I change Crono's accessory from Berserker to Bandana. I have to minimize the RNG increase in the next battle to get the best RNG for the Core battle, and thus Berserker's additional increment is not necessary anymore. In the previous run, I healed Crono's MP once. Changing one kind of equipment takes much time than using one item. 12 frames lost.
 +
 +
'''Inner Lavos battle'''
 +
 +
All thanks to Berserker's additional increment, I've got the favorable RNG, which not only arises critical hits in the first two blows, but also offers a RNG that is close to the best RNG in the Core battle. The fastest strategy is to use Crono's normal attack once and Marle's critical hit twice. However, I have to twist it a bit to get the exact target RNG. Here are two things I do:
 +
 +
# In Marle's first turn, Have her attack after Lavos uses "does nothing" action. - "Does nothing" action increments the RNG like your character's attack does, but the increment varies depending on what the current RNG is.
 +
# In Crono's first turn, use Slash instead of weapon attack. - Slash always increases the RNG by 1 unless it is used at multi-enemies.
 +
 +
Slight delay happens due to those changes. However, Both are necessary to minimize the RNG increase and get the exact target RNG in the Core battle. 3396 frames saved.
 +
 +

Marle Critical hit 9999 9999 The inner body has 20000 HP.

Marle Critical hit 9999 20034 Fatal. Once the inner body is dead, both arms also die.</pre>
 +
 +
'''Before Lavos Core battle'''
 +
 +
Unlike the previous run, Crono doesn't need any MP refill. All I have to do is enter and leave the status menu on the fastest timing. 57 frames saved.
 +
 +
'''Lavos Core battle'''
 +
 +
As a result of precise luck manipulation, I've realized a 1/256 chance of getting 3 critical hits out of the first 4 hits. This is the only RNG that allows you to sweep out all Lavos bits before they take any actions. I thus simply fire all the critical hits to the right bit. 3463 frames saved.
 +
 +
*Strategy
 +
 +
<pre>Character Attack Type Damage Total Damage Note
 +
Crono Critical hit 9999 9999 The right bit has 30000 HP.
 +
Marle Normal hit 29 10028
 +
Crono Critical hit 9999 20027
 +
Marle Critical hit 9999 30026 Fatal. Once the left bit is dead, the right and the center also dies.</pre>
 +
 +
Here is an alternative strategy that I tried in the planning phase:
 +
 +
*Switch the roles of Crono and Marle. Crono's normal attack is faster than the critical hit; the aim is shorter animation again. Under this RNG, however, Marle always takes her turn following Crono. That means, you have to wait for her turn enables, move the cursor on her and attack. Unfortunately, the delay is enough for the right bit to interrupt the final blow. It is feasible if you set down the battle speed 3, but that will be slower in the end.
 +
 +
'''After Lavos Core battle'''
 +
 +
Apparently, if you beat the center bit before it uses Time Warp, Lavos roar happens rather late. It's ironic that the quick kill results in losing the time. 96 frames lost.
 +
 +
'''End of Time'''
 +
 +
When the door opens, I put Crono in a position where it is 4 pixels closer to the door, but still keeps the amount of scrolling unchanged. 2 frames saved.
 +
 +
'''Possible Improvements'''
 +
 +
The only thing I can think of is to reduce the duration of screen transitions. Although the duration is consistent in most cases, it varies between a couple of frames in a few cases, especially around the three Lavos battles. Considering that even one key press affects the duration, I think NMI might be related in that. Due to its randomness, I mildly optimized them in making the run. If they all were managed perfectly, I guess another 5-10 frames would be cut off. However, I'm not positive about restarting the run for only lag management, because no one can possibly detect it after all. Unless other timesaver is found, I will never pick up the run again.
 +
 +
'''Credits'''
 +
 +
First of all, I would like to thank everyone who has viewed and posted in the Chrono Trigger topic. Special thanks goes to Gocha for fixing the Snes9x bug that doesn't properly emulate the reset timing in playing back the movie.
 +
 +
I hope you enjoy the run!

Welcome to the Chrono Trigger Speedrun and Advanced Gameplay Techniques section. Here, the Compendium aims to document the fastest Chrono Trigger players alive and the techniques employed to achieve their low times. Other esoteric gameplay information will be presented in addendum, along with pressing issues and possibilities that may shave off even more seconds of playtime. Traditional speedruns are recognized by the Speed Demos Archive, and are videotaped on a console. Emulated speedrun listings also exist, called "tool-assisted speedruns." Emulators are also used for rapidly evaluating new skills and techniques for later application in a traditional attempt. Successful runs have been described as relying on two factors; the first is skill, "that which makes it possible," and the second is luck, "that which makes it happen." Other challenges are presented at end of this area. This page is authored with the help of inichi.

Route List and Notes

This is inichi's route list. Route lists map out a speedrunner's path through a game and explore possibilities and difficulties.

inichi's notes: I made a few mistakes...but fortunately, nothing critical. If I redo the run, I probably won't get a faster record; rather, it might be slower...I'm truly satisfied with this record. It was lucky for me to start and finish the run before college starts, as I had enough time to play the game. That is why I was able to make the Chrono Trigger run in such short time...As for the final battle, I fought Lavos at least 500 times, tested various strategies and made the final. Even though it still has room for improvement, I'm glad it could live up to expectations.

  • The Millennial Fair
1. Set Battle Mode to Wait.
2. Set Battle Gauge Speed and Battle Message Speed 1 (fastest) and Battle Cursor to save the last command.
3. Go to Leene Square and enter the gate to 600 A.D.
  • The Queen Returns
4. Get a Power Glove in Truce Canyon and get a Power Tab and use it on Crono in Guardia Forest.
5. Go to Guardia Castle and watch Marle disappear in Leene's room.
  • The Queen is Gone
6. After Lucca joins Crono, fight 5 Roly Riders to learn Fire Whirl in Guardia Forest.
7. Get a Revive, a Steel Saber, an Iron Sword and a Tonic in the Cathedral.
8. Equip Crono with the Steel Saber, Frog with the Iron Sword and use Slurp on Crono once at the save point.
9. Defeat Yakura and head to Leene's room to see Marle return to the real world.
  • We're Back!
10. Go back to 1000 A.D. and head to Guardia Castle for the trial.
  • The Trial
11. Steal 7 Mid Ethers from three guards who fall down on the way out of the dungeon.
12. Beat the Dragon Tank and get a Shelter. Run away from the Chancellor and enter the gate to 2300 A.D.

inichi's note: I choose not to use Crono's regular attack but Cyclone as a final blow to the head. Also, I use the techs in an efficient way. The order is three Cylones, Fire Whirl and Cylone. This order can decrease the time of body's counter from twice to once and the need to use Tonics from three times to two. This strategy is 10 second faster than Hero's one.

  • Beyond the Ruins
13. Get a Berserker, a Lode Sword and a Lode Bow in Lab 16.
14. Equip Crono with the Berserker and Lode Sword and Marle with the Lode Bow in front of the Arris Dome.
15. Beat the Guardian and get a Mid Ether in the storage room.

inichi's note: I beat the Guardian before it revive the bits. I equip Crono with Berserker. First, I kill one bit. Then I wait until Crono attacks the Guardian twice. Because it uses counter attacks on Crono, Marle or Lucca needs to use Tonics on Crono twice. After Crono attacks it twice, I kill the other bit. Then I use regular attacks on the Guardian again and again until it breaks down. This strategy is 50 seconds faster than previous one.

16. Watch the video of the day Lavos appeared, and get a Bike Key from Doan.
17. Win the race against Johnny and recruit Robo in the Proto Dome.
  • The Factory Ruins
18. Enter the Factory and equip Crono with the Power Glove on the save point.
19. Get a Shelter, a Titan Vest and a Plasma Gun in the Factory.
20. Before the battle with the R series, use Cure Beam on Crono and Lucca twice and set Battle Gauge Speed 4.

inichi's note: The main reason [for the gauge speed change] is to decrease the number of enemies' attacks. You can see the strange space between the second Cyclone and the third one in the R-series battle. If it remained Battle Speed 1, two or three R-series's attacks cuts in that space. It's enough ground for me to change Battle Speed to something slower considering the animation of their attack takes more than 10 seconds, and this battle finishes in a short time -- about 1 minute.

21. Defeat the R series and go to the End of Time.

inichi's note: In the Factory, I select the suitable combination of enemies for speed. The mixture of 5 Alkalines and Acids is random. And I only fight when 5 Alkaline appear, as only 5 Alkaline's experience points enables Lucca to level up to 8 to 9 before Heckran. Besides, Alkaline's defense is much weaker than Acid's; Crono's Cylone can quickly kill them. I assume this strategy is 20 seconds faster than previous one. I also pick up the Titan Vest. It is not equipped but useful to exchange for Ayla's Ruby Vest.

  • The End of Time
22. Set Battle Gauge Speed 1.
23. Learn Magic from Spekkio.
  • The Village of Magic
24. Head to Heckran Cave in 1000 A.D. Get an Ether and a Mid Ether on the way to Heckran; defeat him.

inichi's note: I use Slash and Flame Toss on the two Henches. It's the fastest way to finish this battle. Lucca levels up from 8 to 9. For Heckran, Crono only uses Slash rather than Lightning. The reason is, Slash's animation is 3 seconds shorter than Lightning's. When Lucca's Level is 9, the amount of the damage of Antipode is about 10 times bigger than when her level is 8. These modifications provide little increase, though enough to replace Slash with lightning. I assume this strategy is 10-15 seconds faster than the previous one.

  • The Hero Appears
25. Go to Zenan Bridge in 600 A.D. and speak to the Knight Captain about rations.
26. Go to Guardia Castle and get an Ether and talk to the chef for a Jerky and a Power Tab.
27. Use the Power Tab to Crono and a Mid Tonic on Lucca and Marle in front of Zenan Bridge.
28. Give the Jerky to the Knight Captain.
29. Fight enemies on Zenan Bridge and equip Crono with the Berserker before fighting Zombor.
30. After defeating Zombor, equip the Power Glove on Crono in front of Denadoro Mts.
  • Tata and the Frog
31. Climb Denadoro Mts. and get a Mirage Hand at the bottom.
32. Get 2 Mid Ethers, a Silver Stud and a Silver Earring on the way to the top.
33. Equip Robo with the Mirage Hand and use a Shelter at the save point.
34. Defeat Masa and Mune and get a Bent Hilt.

inichi's note: I attack not Masa but Mune. I do this because when Masa sleeps from Hypno Wave, Mune's movement completely stops. He only stands being given the attacks. It's an easy battle. For Masamune, Lucca and Robo use Firepunch. Crono uses regular attacks or Mid Tonics as needed. Immediately remove his Tornado Energy build-up with Slash.

35. Buy 11 Tonics, 41 Mid Tonics, 21 Revives, 11 Shelters and 11 Heals in the Porre Market.
36. Get a Magic Scarf and a Bent Sword in Frog's house.
  • The Rare Red Rock
37. Speak to Melchior and head to Mystic Mts to get a Berserker.
  • Footsteps! Follow!
38. After Ayla's party, go through the Forest Maze and equip Ayla with the Berseker and Crono with the Magic Scarf in front of the Reptite Lair.
39. Wait until an Evilweevil digs a hole to the lower right of the first hole, and go through it.
40. Get a Mid Ether, an Elixir and a Full Ether on the way to Nizbel.
41. Equip Ayla with the Titan Vest, Crono with the Ruby Vest and the Silver Earring and Robo with the Berserker and use a Shelter on the save point.
42. Defeat Nizbel and make Azala return the Gate Key.
  • The Masamune!
43. Head to Melchior's Hut and have him repair the Masamune.
44. After getting the Masamune, head to Frog's house and show it to him.
  • Magus' Castle
45. Go through the Magic Cave and equip Robo with the Power Scarf and Frog with the Berserker in front of Magus's Lair.
46. Get 2 Mid Ethers before fighting Flea.
47. After beating Flea, use 3 Mid Tonics on the three party members.
48. Beat Slash and grab a Slasher and Mid Ether. Equip Crono with the Slasher, Robo with the Tin Arm and Frog with the Power Glove and use a Shelter on the save point.
49. On the long way to Magus, get a Mist Robe, a Dark Mail, a Doom Finger and a Speed Belt.
50. Equip Frog with the Dark Mail and the Berserker and Lucca with the Magic Scarf on the save point.
51. Defeat Magus.

inichi's note: Naturally, the healing can't keep up with Magus's magic attacks, so I don't heal Lucca and leave her dead. Only when Magus's weakpoint changes into fire, I revive her and use fire. With this party's equipment, only Crono can survive Dark Matter. I quickly revive Frog and Lucca, use Mid Tonic on Crono twice, and use Crono's regular attacks and Fire. This strategy is one minute faster than the hero's one. Barrier is not very helpful because you have to not only use Barrier on someone but also heal him to survive Dark Matter. After all, the number of times using items is almost the same in a battle without Barrier. Besides, Magus only does nothing between each Dark Matter, which means it would have little effect at a time if the battle finishes a turn or two earlier by using Barrier. Considering it takes at least 25 seconds to get a Barrier, it is best to forget it. [As it turned out, the timing of inichi's Magus battle and Magus's behavior were extremely lucky to the point of nearly total perfection.]

  • Forward to the Past
52. In front of the Dactyl's Nest, take the Dark Mail and the Berserker from Frog, and the Magic Scarf from Lucca.
53. Climb the Dactyl's Nest and get a Mid Ether and a Meso Mail on the way.
  • Unnatural Selection?
54. After Ayla joins the party, head to the Tyrano Lair and give the Silver Stud to Crono and take the Berserker from Ayla in front of the Lair.
55. This is where the real fighting begins. Rescue Kino and fight enemies 27 times in front of the room where Nizbel is.
56. When Crono and Ayla's MP run out, use a Shelter on the save point.
57. Fight enemies 16 times at the same place. While fighting, take the Silver Stud from Crono and give it to Ayla. When Crono and Ayla's MP run out, use a Shelter on the save point.
58. Fight enemies 18 times at the same place. While fighting, take the Silver Stud from Ayla and give it to Crono. When Crono and Ayla's MP run out, use a Shelter on the save point.
59. Fight enemies 16 times at the same place. While fighting, use a Mid Ether on Ayla and equip Marle with the Speed Belt.
60. Beat Nizbel II and get a Full Ether beside the switch which opens up the locked door to Azala's room.

inichi's note: I replace Robo with Marle for learning Twister to use on the Nus. Vite Bolt five times can easily render Nizbel dead.

61. Switch out Marle for Robo. Get a Mid Ether in Azala's room and beat Azala and the Tyrano.

inichi's note: I defeat the Tyrano before it breathes fire. For this purpose, I choose Marle as a third member and give her Speed Belt. First, I use Slash once and Cube Toss three times on Azala. Then Marle casts Haste on herself. After Tyrano's defense weakens, I use Spincut and Cube Toss six times on Tyrano. [Later, inichi commented...] Use Robo instead of Marle. Use Twister 2 times, and Azala falls. After Tylano's defense weakens, use Twister 4 times, then Tyrano breathes fire. Wait until Tylano's defense weakens again, then use Twister 3 times. Perhaps, a few physical attacks will be needed. Less number of attacks would save time (10-15 seconds?).

  • The Magic Kingdom
62. Head to Enhasa and fight 6 Nus and get a Speed Tab and a Magic Tab.
63. Tell the lady in Zeal Palace to plant her plant, which creates the Sunken Desert in 600 A.D.
64. Fight the Golem and wait until the three party members fall. The Prophet sends Crono to 65000000 B.C.
  • Break the Seal!
65. Get a Lumin Robe, a Gold Earring and an Elixir in the Arris Dome, and a Mid Ether and a Swallow in the Forest Ruins.
66. Since Ayla's TP lacked three points of learning Dino Tail, inichi fought three Mutants in Lab 32.
67. Before the Sunken Desert, equip Crono with the Swallow, Marle with the Magic Scarf and Robo with the Speed Belt and use a Shelter.
68. Steal a Barrier from Hexapod.
69. While fighting enemies, go around the first room and second room and collect a Full Ether, an Elixir, an Aeon Suit, a Full Ether, a Memory Cap, an Aeon Helmet, a Hyper Ether, 5000G and a Full Tonic. Twister is the best way to end the battles faster.
70. Before the battle with Retinite, give the Magic Tab and the Speed Tab to Marle.
71. Beat Retinite and get two Mid Ethers in Fiona's Villa.

inichi's notes: First, I use Ice 2 to weaken the defense of the bottom and the top. Then, I use Confuse again and again on the bottom and the top. A final blow to the top and core is Falcon Hit. It can completely prevent the Core from escaping. Sad to say, it is difficult to use Tail Spin. Tail Spin surely can get the damage to Retinite without using Ice 2. But unless the enemy gets near Ayla, I can't use it. Considering Retinite moves in all directions in this battle, it is difficult to use it efficiently. I would waste time hoping it to get near Ayla and remains. To make matters worse, if Ayla uses Tail Spin, the Core is also dead. Once the Core disappears, the remains gain their agility and use strong attacks on all members. I would be forced to heal, which wasn't needed before, and lose a lot of time.

On the other hand, Confusion can be used no matter where Retinite is. I can efficiently accumulate the damage to the bottom and the top, keeping the Core alive. As long as the Core is alive, once their defense weakens -- however many times they may be attacked -- their defense never increases. The damage of Confusion is so big that I can beat Retinite until the Core absorbs its HP with the bottom and the top. But, only when Retinite stands above Ayla, the Core is not involved with Tail Spin. So perhaps I will use Tail Spin once to the bottom. Regarding Haste, I used it in the previous run. But I found it's not necessary. Crono has 15 speed naturally at this point. Besides, this battle ends in a short time. The time Haste could save is less than the time of the animation of Haste. Haste is only useful in long battles such as Lavos's.

72. Drop Robo off at Fiona's to help her, and head to Fiona's shrine in 1000 A.D.
73. Sell 1 Hyper Ether, 51 Mid Tonics, all the weapons, armors and headgear except the Lumin Robe and the Aeon Suit and buy one Vigil Hat and one Sight Cap in Fiona's Shrine.
74. Equip Crono with the Sight Cap, the Aeon Suit and the Power Scarf and Ayla with the Vigil Hat, the Lumin Robe and the Siver Stud.
75. After collecting Robo, have Lucca save her mom and get a GreenDream from Robo. Head to the End of the Time to fight Lavos.
76. Defeat each form of Lavos. Before the battle with real form of Shell Lavos, equip Crono with the GreenDream and Ayla with the Gold Earring.
77. Beat Lavos and set Battle Gauge Speed 2 on the last save point.

inichi's note: [Changing the gauge speed is] an inevitable step to beat Lavos under the poor condition of my low level party. If I remained at Battle Speed 1, I would never beat Lavos. When I started making the strategy for the final battle, my Battle Speed was 5. Then I tried to advance step by step from 5 to 4, 3, 2 and 1. But I found there is a big difference for Lavos's speed between 1 and 2. when Battle Speed is 1, Lavos acts too fast to kill the left arm before Lavos uses the second doors of doom, which definitely makes it impossible to beat Lavos. If you have save data just before Lavos, compare Lavos's move interval in 1 with one in 2, and you can see how fast Lavos acts in 1. Battle Speed 2 is an absolute requirement for my low level party to beat Lavos.

78. Beat Lavos and the Lavos Core.
  • inichi's Lavos Notes
Dragon Tank: Falcon Hit once
Guardian: Falcon Hit once
Heckran: Twister twice
Zombor: Falcon Hit once and Robo's regular attack
Masamune: Twister twice
Nizbel: Lightning, Ayla's regular attack and Twister twice
Magus: Attack until his weak changes to Shadow and Twister three times
Azala/Tyrano: Cube Toss three times on Azala. Cube Toss and Confuse four times on Tyrano
Giga Gaia: Twister five times

For the remaining three battles...

Crono: LV 33 Swallow, Sight Cap, Aeon Suit, Greendream
Ayla: LV 34 Fist, Vigil Hat, Lumin Robe, Gold Earring
Marle: LV 32 Lode Bow, Hide Cap, Hide Tunic, Magic Scarf

Here are the items I use...

Lavos Shell (real form): 1 Revive
Lavos: 1 Full Tonic, 1 Mid Ethers, 2 Full Ethers, 3 Elixirs, 4-5 Revives, 1 Barrier
Lavos Core: 2 Mid Ethers, 2 Full Ethers, 0-2 Revives, 0-2 Heals, 0-1 Lapis

Here are the techs I use...

Lavos Shell (real form): Dino Tail three times and Confuse four times
Lavos: Dino Tail 15 times, Haste once and Cure once
Lavos Core: Dino Tail 11-12 times, Confuse 7-8 times and Haste once

[inichi later commented...] Replace some of Crono's confuse with some Ayla's Dino Tail in the Lavos Core battle. In fact, there is insane luck concerning accurate key response needed to reach the Lavos Core battle and have the center bit change the ages in the ideal order. I was so afraid to spoil the best chance of winning that I chose killing the right bit before it revives the center bit as a safe move. But, there are some times between it relieves and uses Dreamless. So here, you can replace some of Crono's Confuses with some of Ayla's Dino Tail. Fewer attacks will surely save a lot of time. Besides, Crono's second Confuse to the center bit is an unnecessary attack by my mistake. I think it is this last segment that the most improvement could be found in my run. (20-30 seconds?)

  • Room for Improvement?

After reviewing the run, inichi made several notes regarding spots that could be improved to make a perfect run.

  • Get a critical hit on the last Roly Rider in Guardia Forest (3 seconds)
  • Don't get a Tonic, Revive, or Heal at the Cathedral (2 seconds)
  • Improve fight with Yakra to best time (inichi's best is 10 seconds shorter)
  • Get another critical hit on the Dragon Tank battle (3 seconds)
  • Get a Shelter faster after that battle (1 second)
  • Improve transition and activities in 2300 A.D. (3 seconds)
  • Use the first Cyclone to more than 2 Alkalines at the Factory, which probably will enable you to kill all enemies before being attacked, and use HealBeam on Crono and Lucca only once (7 seconds)
  • Don't pick up a Mid Ether on the way to Heckran (2 seconds)
  • Defeat Zombor before the bottom portion attacks and save the game faster (6 seconds)
  • Run right through the enemies prior to the Masamune at Denadoro Mts (5 seconds)
  • Don't stop in the Forest Maze (2 seconds)
  • Perform luck manipulation to get EvilWeevil to dig the lower right hole faster, and don't miss saving data (15 seconds)
  • Improve transition from Reptite Lair to Melchior (3 seconds)
  • In Magus's Lair, kill enemies on the way to Flea before they attack to decrease Mid Tonic usage (5 seconds)
  • In Magus's Lair, complete the guillotine room faster, don't equip Frog with the Dark Mail, and don't use a Shelter (5 seconds)
  • Removing Frog's Dark Mail at the Dactyl's nest is no longer needed (1 second)
  • Don't forget to save data while fighting the 16 enemies at the Tyrano Lair (1 second)
  • Don't equip Marle with the Speed Belt so that a higher tech point enemy mix is preserved (2 seconds)
  • Don't switch Marle to Robo before the Azala battle (2 seconds)
  • Changing Robo and Marle in front of Enhasa is no longer needed (12-15 seconds)
  • Higher TP allows Ayla to learn skills without fighting three mutants in 2300 A.D. (10 seconds)
  • For the Retinite sequence, don't heal Marle, give her two tabs, or get stuck in the sand (8 seconds)
  • Give the Magic Tab to Marle before fighting Lavos's true form (-1 second)
  • Improve the Lavos battle with aforementioned strategies (20-30 seconds)

inichi's note: Judging from the total number, 3:32 would be possible if you don't settle for anything less through most of the run, and you might get 3:31 if the in-game clock is on your side. However, 3:30 will be impossible unless some new strategy is found.

Route List and Notes, 100%

Intro

I started speedrunning Chrono Trigger in preparation for Awesome Games Done Quick 2011. I'd hoped to get a submittable run soon afterward, but being a full-time mom means that I don't often get chances to attempt a 6-hour single-segment run. So it took over a year, but I finally completed this run. In a way, it's good that it took this long, because I was able to find lots of little improvements during that time.

This run is far from perfect; there are lots of little mistakes, as well as two big mistakes in Magus's Castle, but I was able to beat my goal time (under 6 hours real-time and under 5:45 game time), so I'm happy with it. Besides, there are other games I want to run. ;)

Tricks used throughout the run

  • Battle speed

Most of the time I keep the battle speed on 1 (fastest). However, I tested every boss battle with different speeds, and found a few where it's better to turn down the battle speed. The main benefit to doing this is having more reaction time, so I can get more turns in between the enemy's turns.

  • Battle cursor memory

When the battle cursor is set to memory, it behaves a little differently for each menu. In the Item menu, the cursor will stay on whichever item you last moved it to, but in the Tech menu it won't stay on a specific tech unless you actually select that tech and target an enemy.

  • X to attack

A little-known fact about this game is that during battles you can hold the X button to automatically select "Attack".

Running away To run away from battles quickly, hold R and L and go into either the Tech or Item menu, wait for about a second, then exit the menu. Almost every time you'll immediately escape the battle.

Specific comments

  • Cathedral

In preparation for Yakra, I needed Lucca to have lower HP (preferably under 30), and there are two forced battles where she can take damage. The first one (Naga-ette x4) can be really random, depending on how many times they use their Slow spell instead of just attacking Lucca. This battle wasn't the best, but it could have been much worse. The second battle (Hench x3, Diablos x2) was pretty much perfect.

Yakra: Yakra likes to counterattack, which not only wastes time but also hurts quite a bit, but he'll only do it if all three party members are alive. It's fastest to have Lucca die as soon as possible, and Yakra obliged by attacking her first. I also got more criticals in this battle than usual.

  • Escaping Prison

Things went pretty well here; most importantly, I didn't get caught by either guard. Those shield enemies are a pain to avoid, by the way.

Dragon Tank: The most consistent way I've found to defeat Dragon Tank is to wait for it to heal twice, have Crono attack the head 6 times and Lucca attack it once, then 3 cyclones and 2 fire whirls. Unfortunately, on Crono's 4th turn I accidentally had him attack the body instead of the head, and then proceeded to waste Lucca's next turn with attacking the head. It didn't waste much time, but it still looks ugly. Afterwards, at the bottom of the stairs normally the two guards stop you and there's a bit of dialogue, but I managed to skip all that.

  • Lab 16

You can save time here by purposely running into rats; you won't get into a battle while the "Stole a tonic" message is on the screen, and there are two places in particular where you can save a few seconds by doing this. I didn't have any tonics to spare, though, so unfortunately I couldn't take advantage of this trick.

  • Arris Dome

Guardian: This took longer than usual because the game was being stingy with criticals. As a side note, I only have one tonic and one revive available to use in this battle. I got into my first unintentional battle on the way out of here, and it's not even a hard one to avoid, boo.

  • Factory

That first Acid should have died in 3 hits or less - seriously, Robo usually does about 6 damage. In the next battle, the ratio of Acids (orange) to Alkalines (green) is random. If you attack an Alkaline while there is at least one Acid still alive, there's a chance it will do a counterattack. I take that chance, though, if I can target a bunch of enemies with Cyclone.

R-Series: This is the first place I turn down the battle speed; it's needed so you can actually get a turn before they kill you. I attack the enemies in this order (front, back, back, front) to avoid their nasty "throw your character back and forth" attack.

  • Heckran's Cave

I failed to avoid the Cave Bat x3 battle, which is kind of tricky to do anyway.

Heckran: I used to think I needed to turn the battle speed down to 2 here; the main problem was that during Heckran's second phase, Crono wouldn't get his turns quick enough to be able to heal before Heckran could possibly kill someone.

  • Truce Canyon

This is the hardest battle skip in the game; I waited a few extra seconds to be sure I'd get it.

  • Guardia Castle

It might not look like it, but I saved a couple seconds while talking to the chef; by running up and down, you can make some of the dialogue boxes disappear faster.

Zombor: It would have been nice if Crono had attacked the head more, but oh well.

Masamune: In the first battle, if both of them are put to sleep, it's better to attack the one of the left because he won't do anything after being woken up. In the second battle, I was lucky that the last Fire Punch actually killed him, or I would have had to deal with his counterattack

Nizbel: I found that if I waited to cast Lightning until right after Nizbel's first turn, for the rest of the battle I'd be able to cast Lightning right after he released electrocution energy, thereby minimizing the number of times Ayla and Robo attacked while his defense was up.

Afterwards in Ayla's hut, she normally stops you for a couple seconds when you try to exit; this can be avoided by talking to her and exiting while the dialogue box is still onscreen.

Melchior's Hut I don't really know why this works, but you can make the cutscenes here go about 5 seconds faster by continuously walking into Melchior at certain points.

  • Truce Canyon

I failed the battle skip this time. :(

  • Magus's Castle

Flea: I wish I better understood how this battle works. If you put the Berserker on Frog and just let him attack, sometimes Flea will get "stuck" for a while, where he just stands there and doesn't attack. In most of my previous runs I couldn't get this to happen, so I was really happy when it happened in this run. I let Robo die so Flea would stop doing The Stare.

Slash: Not much to say here. Crono, who deals the least damage, is the healer; Frog, who deals the most damage, is the only attacker near the end of the battle when Slash counterattacks every move.

The trapdoor room is the ugliest part of this run. Normally I use the pattern on the floor to avoid all the trapdoors. However, I happened to be playing on a different TV than I have in the past, and this TV was much darker and had no menu button on it, so I couldn't even change the brightness. So, since the floor looked completely black, I had to guess where to go to avoid the trapdoors, and unfortunately I guessed wrong - twice. In addition, since I'm not used to falling down, I didn't know which savepoint was the teleporter, and so I guessed wrong again. There were also a few other little mistakes: getting stuck on the second conveyor belt with the scythes, accidentally exiting a room as soon as entering it, and using Slash on the wrong enemy, so overall this is the worst section of the run. However, the Magus battle made up for all that.

Magus: During his first phase, Magus will change his weakness when he is hit by that weakness or when Frog has attacked him twice. I can only take advantage of lightning or fire weakness; oncee Magus's weakness is one of those, I let Frog attack once to lower Magus's magic defense before casting the spell on him. During the second phase, at full HP Crono can just barely survive Dark Matter. In the past, with really bad luck, this battle has lasted up to 16 minutes; in this run it was less than 10, which was great. In fact, I was so excited when Magus went into his second phase so quickly that I had Lucca cast Fire too soon and ended up healing him, whoops.

  • Dactyl Nest

There are two battles on the second screen that are tricky to avoid, but I managed to pull both of them off.

  • Tyrano Lair

I fight 7 battles here to learn Volt Bite before the next boss.

Nizbel II: This has been one of the hardest bosses in past runs; I had one good run attempt end here, and previous best run lost 2 minutes here because I almost died. The problem was that if I was just a little bit too slow selecting attacks, Nizbel would get too many turns and have a good chance of wiping me out before I could do the last Volt Bite. For this run I finally decided to turn the battle speed down to 2, and it definitely paid off. Also, Lucca inexplicably managed to survive this battle, which has never happened before; unfortunately, she couldn't take advantage of the extra tech points.

Black Tyrano: I don't heal after Tyrano's first countdown so that when he chomps my characters, he doesn't get healed as much. This allows me to be able to kill him before his second countdown ends, without having to do any extra attacks in between the two countdowns.

After powering up the pendant in the Zeal Kingdom, I make a slight detour to Medina to pick up a better weapon for Crono (Swallow) and a speed tab.

  • Lab 32

It's about 5 seconds faster in real time to walk across the ruins, but about 30 seconds faster in-game time to do the race. (For some reason, the race doesn't count in the in-game timer). Since I'm going by SDA timing, which using in-game time, I opt to do the race again.

  • Sewer Access

I love going through this place with everyone at 1 HP. ;) The only real thing of note here is that I skip the second cutscene with the frogs by simply walking to the right of the cutscene trigger.

Mud Imp: The most annoying boss in a speedrun, ugh. This battle can go real bad real fast, especially if Hypno Wave refuses to work on the Blue Beast. (If Hypno Wave works on both beasts, the blue one will never wake up, but the red one will.) I actually had decent luck this time.

  • Mt. Woe

I need to defeat 3 Rubbles here; Ayla and Crono will learn Falcon Hit, and Lucca will be well on her way to learning Flare at the proper time. There are 4 Rubbles along my path, and if I happened to be extremely unlucky, the third Rubble respawns if you leave and re-enter the screen. (Fortunately I didn't need to do that.)

Giga Gaia: Turning the battle speed down allows me to defeat him before he regenerates his arms a second time, without having to do extra Napalms.

There are a few places in the game where if you press X at the right time, you can go into the menu when you're not supposed to be able to; just after Mt. Woe falls is one of those times. Doing this skips the scene fade-out and fade-in, which saves a few seconds.

  • Zeal Palace

I have to tell the lady not to burn the plant in order to open up the Sunken Desert sidequest.

Dalton: Crono doesn't need anymore tech/experience points...

  • Ocean Palace

I got into one battle here with Thrashers and Lashers that I should have been able to avoid. In the two rooms with Scouters where you have to press the switches, it's not that difficult to avoid fighting the Scouters once you figure out how. (The trick is to walk - not run - into the back of the Scouter.)

Golem Twins: This battle is all about timing. I want to keep them copying fire because it's their weakest attack, so I always need to do Fire2 right after Falcon Hit. I wait for both of them to attack before doing Falcon Hit so they don't manage to sneak an Iron Orb in there. In previous runs I started this battle with Lightning2, because I didn't think Lucca could cast Fire2 before one of the Golems would get a second turn, unless I turned the battle speed down. However, I found that I could keep the battle speed at 1, and if I waited a split second before choosing Crono's action, Lucca's ATB gauge would fill during his turn and she would be able to act before the Golems' second turn. (Like I said, it's all about timing.) This also allows both Crono and Ayla to use mid tonics right at the beginning of the battle, which means I most likely won't have to heal during the rest of the battle. Lucca is the only person who needs to survive here.

I knew it was possible to do the menu trick here, but this was the first time I'd ever managed to do it!

  • Blackbird

I bring Ayla because she can fight without a weapon, and Robo and Lucca to get tech points. The only stuff I get back is my items; that way I can equip a weapon on both Lucca and Robo so they will be able to act against Dalton, and so I'll have healing items for that battle. After leaving the Blackbird, you get all the stuff except money back anyway.

Dalton (again): Since Dalton always counters with Iron Orb, I found that if I wait for him to attack, then have Ayla do Rock Throw, then immediately heal her, there was no possibility of Ayla dying.

I don't immediately put Magus in my party, because there's 5 seconds of extra dialogue between Gaspar and Magus if he's in your party at the End of Time.

  • Millennial Fair

You have to have 40 silver points to get the Crono clone, so I fight Gato 3 times. Normally if you fail Norstein Bekkler's mini-game, he charges a price dependent on how long you stayed in the game. However, all my money was stolen by Dalton, so I *have* to win the game.

  • Death Peak

I fight two Krakkers before the first Lavos Spawn so Robo can learn Robo Tackle.

Lavos Spawn 1: Fire Tackle makes this battle way too easy.

Lavos Spawn 2: As someone in my stream chat put it: He's so scary, he makes you want to run away!

I now need to fight a total of 54 Krakkers (including the two I fought earlier to learn Robo Tackle). This is so that Lucca will learn Flare at the right moment later on. Ice2 is about a second faster than Fire2, and about 2 seconds faster than Lightning2, so it's best to use Ice2 when possible.

Lavos Spawn 3: Since my characters have leveled up from all those Krakkers, this battle goes faster than the first Lavos Spawn - or at least, it would have if I'd thought to heal Lucca before the battle started.

The cutscene where Crono comes back is about 15 seconds longer if either Lucca or Marle is in the party; so I switch Lucca out of the party, but the scene just feels awkward with Robo being the one to welcome Crono back.

Now, onto the sidequests! The first few sidequests are done in order to get the Blue Rock and learn Flare as soon as possible, which consequently gives access to the strongest triple tech in the game: Omega Flare.

  • Northern Ruins

This place has three easy forced encounters and no boss to worry about, so it's the first sidequest completed.

  • Giant's Claw

The all-important Blue Rock is here, plus two Rubbles that give 100 tech points each. (I've never failed to kill the Rubbles here.)

Rust Tyrano: The Red Mail that I steal here will be used for Atropos and Son of Sun. I save a bit of time by timing things so that I can select Magus's attack while Crono and Ayla are performing Falcon Hit.

  • Geno Dome

Every battle here is inescapable, so it's a good place to get tech points. In most of the battles, I wait a split second before selecting Magus's attack so that I can select Lucca's attack during Magus's spell animation. I'd also like to note that I hate getting that one robot to follow me. :(

Atropos: My brother, Brossentia, gets the credit for "defeating" this boss. In other words, he held the controller while I took a much-needed potty break. ;)

Lucca learns Flare right before the boss; however, even though Robo has the Blue Rock equipped, they don't actually learn the triple tech Omega Flare until you go into the menu, which is why I do so and exit immediately.

Mother Brain: Now you can see the overpowered attack that is Omega Flare!

Son of Sun: I tested many different battle speeds for this battle, and speed 3 seems to work this best. At this speed I can usually get all 10 hits in only two Roulette rounds, without the battle being unbearably slow. I made one mistake, though: I had Robo heal himself right before the second Ice2, instead of right after, so he ended up dying. At least it was near the end of the battle and didn't make much difference. (I revived him so he would get the experience and tech points.)

  • Ozzie's Fort

Theres a bit of extra dialogue with Magus in the party, but since I need him for the battles here, it's not worth it to switch him out and back in.

Great Ozzie & Co.: Thanks to Nitrodon for this strategy. If I had simply done two Omega Flares, I would have had to sit through three counterattacks after the first Omega Flare. However, casting Dark Bomb on Flea first means that he will die after the first Omega Flare, and I'll only have one counterattack to deal with. Even though I take an extra turn with this strategy, it's still a few seconds faster.

I some stuff needed for the Sunstone, and then it's off to the Sunken Desert.

Retinite: By timing attacks so that I can select Magus's during Robo's attack animation, I'm usually able to kill the bottom part before it absorbs from the Core a second time. This makes it so I don't have to heal the Core to keep it from dying (the boss becomes much nastier if that happens). I accidentally had Magus do an extra attack at the end, oh well.

I now finish powering up the Sunstone, then go to do the last sidequest before Black Omen.

Yakra XIII: Too bad I can't use Omega Flare here. At least Marle is useful for providing defense, healing, and being a meat shield at the end.

There were a bunch of times in practice runs where I'd just mash A while talking to Melchior and accidentally select the Prism Dress instead of Prism Helms; that would be a run-killer, because I need the helmets to protect against status ailments in the Black Omen.

  • Black Omen

It might seems strange that I didn't change their equipment until after the first battle in the Black Omen. I did this so that Magus would have the Speed Belt equipped for the Laser Guards; otherwise, the Laser Guards would get to act before he could kill them.

Mega Mutant: The upper part has 4600 HP, so sometimes one Omega Flare isn't quite enough to kill him.

I re-equip the Speed Belt on Magus and change the battle speed to 2 for most of the Black Omen; this helps minimize the number of attacks enemies get before I run away/kill them. On each elevator, you'll get between 0 and 3 inescapable battles; I got pretty lucky with these (no battles on the first elevator and only one on the second). Unfortunately, I ran into two unintentional battles: Incognito x3 and Ruminator x4.

Giga Mutant: Omega Flare rules! (What else do I need to say?)

Terra Mutant: See Giga Mutant.

Lavos Spawn 4: I break the "don't attack the shell" rule with my final attack, because it saves so much time.

Zeal 1: Zeal's first attack is always Hallation, then she does Hallation again when her HP drops below half, and then her attacks start back at the beginning so she does Hallation once again. So basically, I'm in no danger of dying in this battle.

Mammon Machine: Mammon Machine stands still...for Omega Flare!

Zeal 2: This is one of the scariest battles in a single-segment run. I can't spam Omega Flare here because the hands' counterattacks are time-consuming (not to mention dangerous). I want to keep track of Zeal's HP, because when it goes below half, she does Hallation followed by MP Buster; I need to be ready to revive anyone who might die from the hands and to use a megalixir. Then once Zeal's HP goes below 4800, I can finish her off with Omega Flare.

Lavos (outer shell): Most of these are pretty self-explanatory. With auto-haste on Robo, most times it's faster to use ethers during battle than in between battles.

Lavos (inside): My main goal at the beginning is to kill the right arm before it does Protective Seal (which removes immunity to status ailments); this is usually possible by having battle speed at 2 and using Doublevbomb for the third attack instead of Omega Flare (Magus just takes too long to get his turn).

Lavos Core: A perfect battle would go like this: kill the left bit with two Uzzi Punches, damage the middle bit so he'll die after two Omega Flares, wait for the right bit to lower its defense, then get in three Omega Flares before it revives the other bits; repeat, while not attacking when the right bit has its defense up; then do a single Uzzi Punch to kill the right bit. This battle can be a real pain if the middle guy decides to do anything other than Time Warp; thankfully he only did that once.

At the time I did this run, near the end of the battle I didn't notice the right bit turn its defense off the second time, so I felt really dumb for just sitting there waiting when I should have been attacking. However, now that I've gone back and watched the run, I've realized that the right bit never actually turned its defense back ON, which is really, really strange. So when it turned its defense off a second time, I just assumed it was turning its defense on. At least I don't feel so dumb now. :P

Advanced Gameplay, Possibilities, and Sequence Breaking

Running Away Quickly and Tech Selection

Discovered by inichi

This enables you to quickly run away from the escapable battles. When the battle begins, hold the L and R buttons, push the A button on tech or item command and push the B button. Then the moment you push B button, you can run away from the battle. By using this technique, I succeeded in running through the four battles in Magus's Lair without receiving any attacks. It saved a lot of time. There's another reason to do this -- to prepare for the next battle by selecting the tech I'm going to use beforehand. For example, I select Cyclone, which is used in the first battle in Tyrano Lair, in the battle in Dactyl's nest before running away. And I select Haste just before Retinite dies because the next tech Marle uses is Haste in the Lavos battle. There are a lot of places I did the same thing in my video.

Delaying the Cotton Candy Scene

Discovered by hero of the day

Due to the way Chrono Trigger handles PC detection, it is possible to reach the exit leading to the Telepod sequence without being stopped by Marle for cotton candy. However, the scene cannot be avoided when returning to the overworld, even after playing through the 600 A.D. Queen Leene / Cathedral sequence.

TAS Route List and Notes

Tricks and glitches

Loading corrupted save data

The game writes hash checksums upon saving; if the checksums don't match, the save(s) will be unloadable and displayed as empty.

Howewer, due to an oversight, it is possible to bypass this check and load corrupted save data by pressing Up+A on the save load screen.

Detailed commentary

Millennia Fair

Marle is picked up. If the Imp's house is entered without her in the party, the game will crash.

Zenan Bridge R1 The game is saved twice to set up save corruption at a later time.

Guardia Continent, Eastern Nebula

The position value 1F3E is partially overwritten with the party's current position, 4A50, resulting in the position 4A3E being stored in SRAM.

Guardia Continent, Imp's House If Marle isn't in the party when entering this area, the game will crash.

The End of Time

The game is saved on a save point, resulting in the corresponding flag being set in SRAM. The subframe reset here is just for show - allowing the save to complete would yield equivalent results.

Zenan Bridge R2

The Zenan Bridge save is loaded. The game is then saved over the End of Time save and interrupted after the location values are written but before the save point flag is removed. This allows us to save anywhere.

Zenan Bridge R3

The game is saved on Zenan Bridge, resulting in a save file with a location value of 2000. We then exit the area and reset while the location value F001 is being written to the save file, resulting in SRAM containing the location F000.

Nu Ending

The location value F000 corresponds to the Nu ending, so the run ends when the save is loaded. Since triggering the ending in this manner wasn't intended, glitched graphics are briefly shown.

Special thanks to

inichi: for demonstrating the concept and making the extremely fabulous published runs.

Ilari: for making lsnes and helping with emulator usage and Lua scripting.

About obsoletions The published any% and NG+ movies both abuse save corruption. This run is faster than both; obsoleting both of them seems to make the most sense.

Old TAS Route List and Notes

written by inichi

Finally, I made it. I'm sorry for keeping the entire movie-making process secret and not posting any WIP on the forum. The expected improvement was so gigantic that I couldn't resist an inpulse to make the run surprising. Also, the submission text is still incomplete. I think this is a bad thing. However, considering these facts:

  • Most part of the run is totally new stuff. So it would take a long time to cover them all, even in Japanese, my native language.
  • This is a long-term project; I started making the run in August 2007.
  • Chrono Trigger is a very popular RPG, and not a few people have been interested in how the run is going.

I thought it would be better to submit the run as fast as I could than to write up full texts and submit it. I will upload the rest of the submission texts little by little. Emulator Details

About the game

Chrono Trigger is a memorable role-playing game developed and published by Square in 1995. The story is about a boy named Crono who travels through time with his friends to save the world from an alien parasite, Lavos. The game is also recognized as one of the best RPG, attracting a lot of new fans even today.

About the movie

This is a 3 hour 59 minute 48 second improvement over Hero of the Day's current published run. The improvement mostly came from massive new tricks and glitches. See the below "Tricks and Glitches" section for details.

Tricks and Glitches

In this section, I will give a full explanation of all glitches and tricks I used in the run.

Item duplication

This is a glitch to duplicate items by loading a corrupted save file.

Mechanics: It takes 2 frames to save the game in Chrono Trigger. some values between 7E2400 and 7E264F are overwritten in SRAM in order in the first frame; the rest of them and values in addresses after 7E264F are overwritten in order in the second frame. That means you can get a half-saved save file if you reset the game in the first frame of saving. Off course, this is an invalid procedure for the game, so the target data is deleted. In Chrono Trigger, however, you can load the corrupted data by pressing A and up/down key at the same time in the load screen.

Also, for the reason mentioned above, you can only affects on 7E2400-264F by resetting in saving. What are in those memory addresses are like this:

  • 7E2400-FF: Item ID (last 14 bytes are unused).
  • 7E2500-FF: Item number (last 14 bytes are unused).
  • 7E2600-4F: Crono's status

How many addresses between 7E2400-264F are overwritten in the first frame are slightly influenced on the previous key presses and cursor movements. Basically, you can manipulate it to some extent by changing them or costing a few frames. To make things easier, I used a lua script.

How to duplicate an item? Item duplications are basically classified into three methods. I'll explain for each method.

Explanation of the chart: Using data is a data that you use to save. Object data is a data that are saved in the glitch-use. Result data is a data you get after the glitch-use. Bronze means Bronze Helm; Hide means Hide Cap. Null means there are no items in the slot. Numbers next to them means item number.

Method 1: 

Using data	Object data	Result data
Null 0		Null 0		Null 0
Null 0		Null 0		Null 0
Bronze 2	Hide 1		Bronze 1
Hide 1		Bronze 2	Hide 2

This method is kind of switching. Only item ID is overwritten, and you can get two items with different ID. This is done in one reset. 

Method 2:
Using data	Object data	Result data
Null 0		Null 0		Null 0
Null 0		Null 0		Null 0
Bronze 2	Hide 1		Bronze 1
Hide 1		Bronze 2	Bronze 2

This method is basically the same with the first one except that the below item ID isn't overwritten. As a result, you can get the same items that have different numbers. This requires extreme precision, unless you insert some null slots around the border, which is slower. This is also done in one reset. 

Method 3:

Phase 1:

Using data	Object data	Result data
Hide 1		Null 0		Hide 1
Bronze 2	Null 0		Bronze 2
Null 0		Hide 1		Null 1
Null 0		Bronze 2	Null 2

Phase2:

Using data	Object data	Result data
Null 0		Hide 1		Null 1
Null 0		Bronze 2	Null 2
Hide 1		Null 1		Hide 1
Bronze 2	Null 2		Bronze 2

Phase3:

Using data	Object data	Result data
Hide 1		Null 1		Hide 1
Bronze 2	Null 2		Bronze 2
Null 0		Hide 1		Hide 1
Null 0		Bronze 2	Bronze 2

This method is the most complicated, but most powerful one of all. With this method, you can extend items over the above null slots. This actually can be done with Method 2. However, it is much slower because it requires you to buy other items for replacement in each use, which takes much time. This method also requires extraordinary precision, unless you insert some null slots around the border, which is slower. You need to reset three times for this method.

How they were used in the run? Duplicating Hide Caps and Bronze Helms and having them in 98 slots with three methods. This is what I did in the first 3.5 minutes in the run. I'll write it down step by step:

First, I bought 1 revive and 20 Tonics from the merchant at the fair for 400G, Crono's pocket money. With Method 1, Two items ID were switched, resulting in 20 Revives and 1 Tonic, both of which were immediately sold. With that money, I bought a Bronze Helm and 5 other items from two merchants. Second, with Method 2, I changed 5 items into Bronze Helms and Hide Caps. Now I had Bronze Helms and Hide Caps in 7 slots. Finally, with Method 3, I extended them over the above null slots. The actual pace is like this: 7-13-25-49-98. Thus, I got Hide Caps and Bronze Helms in 98 slots.

Having the same type of equipment in 98 slots allows you to access various memory addresses via the equipment screen in Chrono trigger. This is actually the only purpose of all item duplications I did in the first 3.5 minutes. I'll explain the detail in the below section.

Accessing various memory addresses.

As stated above, Having same type of equipment in 98 slots allows you to access various memory addresses that you normally can't.

Mechanics: When you call on the individual equipment screen, item ID that corresponds the equipment type that the cursor currently points out is stored in 7E0F00-60; item number in 7E0F61-C2 as well. All they appear in the equipment selection screen. Yes, as you can see, each has only 96 bytes for their purpose. So if you have the same type of equipment in more than 96 slots, item numbers will flow into 7E0FC3 or later addresses. It is required to flow them into 7E0FC4-6 to access various memory addresses. This is why you need to have them in 98 slots at least. I write down the function of those addresses:

  • 7E0FC4: Decides how many the cursor can move in the character selection screen.
  • 7E0FC5: Decides where the cursor is in the equipment screen. It also works as an offset when you equip, which is stored in C2A4AB-A5AA, and it works like this: 7E2600+xx (in Crono's case)
  • 7E0FC6: Decides how many the cursor can move in the equipment selection screen.

In my run, I accessed and overwrote these three addresses: 7E2985, 7E2980 and 7E2990.

    • 7E2985: An address for a third reserve character. You cannot access 7E2983-84 because any appropriate address doesn't have 13-15, 63-65, B3-B5. I stored 0A in 7E2985, which saved a lot of time when accessing 7E2980. Also, although the address is for a third character, it is treated as it is just under the main three characters when no one is in the first or second reserve.
  • 7E2980: An address for the first party character. You can't access 7E2981-82 since any appropriate address doesn't have 11,12,61,62 B1, and B2. This was rather inconvenient, but not much. This address was heavily accessed and overwritten throughout the run to call out a character who must be in a cutscene or to use "Character warping" trick that will be picked up later.
  • 7E2990: An address for the configuration setting. By modifying the configuration setting, you can store any value out of 256 in the address. Because you are accessing it via the equipment screen, if you equip something with it, the value in the address appears as an item in the item inventory. The thing is, you can retrieve any item from this address.

The alternative way to retrieve an item is to use an address of one character of name strings. The problem with that plan is, once you retrieve an item from it, you can't use the character for that purpose again. I needed three different items in the run, Bike Key, Elixir and Green Dream. That means I have to change the item order twice to withdraw an item from another character, which would consume time.

Character warping

Every time you open the pause menu, all your three character X-Y coordinates are stored in proper addresses. However, if a missing number is in your party and he is not in the first, the appropriate address is not updated. And then, if you replace the missing number with a normal character, the character appears on the coordinates which was stored in when you previously opened the menu. Now a second or third character warping happens. After you use the warping trick at least once in an area, coordinates stored in the addresses always take the same value with a normal character one even if a missing number is in your party. Therefore, you can make even the first character warp by keeping the missing number in the party in the first warp, and just replacing him with a normal character.

Very unfortunately, this isn't applied to overworld coordinates. If it was feasible, the run would shrink by another 10 minutes.

Character sliding

Normally, a second and third character mimic the first character's movement. However, if he is a missing number, he can't mimic the first. Instead, the movement he should have mimicked stacks up in proper addresses until a counter reachs 128 and erases them all. With enough such stacks, if you replace a normal character with the missing number, the character starts sliding, mimicking the movement that has stacked up. While sliding, the character can go through any obstacles.

To make the most of this, you need to use the character warping once or change a character order beforehand so that missing number's next X-Y coordinates could be subject to the normal character's one. Otherwise, a character called out will warp far away and start sliding there, which is unfavorable.

Marle join skip

If you talk to either one of the two merchants with Marle in the party, he sets a flag to remove the men who block the way to Telepod area. Thus, you can entirely skip the marle joining cutscene and enter Telepod area.

Alternatively, you can go through those men in the same way as used in the Factory, which will be mentioned in the below section. When you go back from Telepod area, however, they block your path, and you have to go through them again. So it's a waste of time, though it might be useful for a new game+ run.

Pause menu abuse

By opening the pause menu and leaving it when the screen starts to fade out, you can have a few frames to move in another direct. If you repeat this again and again, you can get to a point that would trigger a certain event, keeping the fade-out status. If you set a flag that determines if the event completed and let the fade-out be done, you are brought to the previous room and it is considered the event already finished.

This trick could have been featured as a main timesaver to skip some boss battles. However, due to the discovery of the more sequence-break glitch, the trick was used in only one place moderately: Telepod area, to skip Lucca’s dialogue.

Playing around at the Telepod area

Unless Crono picks up the pendant, you never lose control, which provides a first huge play-around time. This is useful not only to mess around, but also to make a moving counter of Taban and Lucca faster. Normally, the moving counter of them are incremented by 1 per 4 frames. However, if you keep touching him/her, it is incremented by 1 per 1 frame. Also this is a necessary step to completely skip Middle Ages. See the below section for details.

Middle Ages skip

In every gate transition, a flag that determines if you are in warping is set a few frames before the fade-out completes. That is, you can escape the area with the flag is on if you interrupt another fade-out, which was the entrance of Telepod area in my run's case. If you enter the gate area with the flag is on, the game considers you just got through the gate, and consequently open the gate with your character. In Telepod area's case, the game also considers you just returned from Middle Ages, and increments the storyline counter enough to trigger the trial events. A big timesaver, certainly. Also, Marle must be in the party when you enter the castle; otherwise the game freezes right after entering the castle.

Alternatively, I tested to go to Guardia Forest gate area instead of entering the Telepod area right soon, hoping to entirely skip the trial cutscene. As expected, Magus appeared from the gate; however, the gate disappeared soon and I wasn't able to go into it, proving it not useful for the run.

Candy skip

A flag that triggers the candy cutscene is set when Marle joins in Crono. Since Crono and Marle never met in a intended way in the run, the candy cutscene also never happened.

Getting out of the trial

In the flashback scene of the trial, the game makes the first character appear there. And if the first character isn't Crono, you can move him at free. If he is a missing number, nobody shows up there, but you can still open the menu. And then, if you call out a normal character, it meets the condition of "Character warping trick" and he appears in the same position with where you previously opened the menu.　In my run, it is the south entrance of Leene’s Bell area. At this point, the storyline counter is enough to trigger the Marle runaway cutscene. Thus, you can skip the latter half of the trial and all the events in the jail. A huge time-saver, off course.

Also, Lucca must be in the party when you enter the castle; otherwise the game freezes after Marle runs out of the castle.

Arris Dome skip

Johnny appears at Lab 32 if you enter there with a Bike Key. That means you can completely skip Arris Dome, where you can get a Bike key from Doan after you finish all the events there. This may be not intense, but definitely a solid timesaver.

Bike Race skip

This is very similar to Middle Ages skip. A flag that determines if the race was over is set a few frames before a fade-out to the race track completes. Also, the fade-out is slower than the usual screen transition one. The thing is, if you start a fade-out to overworld just after you turn the key, you can escape to the overworld with the flag is set. "Character warping trick" only makes it possible, so you need a set up beforehand. I used a north edge of Lab 16 east for that purpose because it has the same Y coordinate with the south entrance of Lab 32. You may notice I did a strange behavior in Lab 16 east. That is exactly the set up for Bike Race skip.

Alternatively, you can directly get the needed Y coordinate at the south entrance of Lab 32. However, it requires to go out and in Lab 32 to avoid the freeze that results from the lack of characters. After all, it will be slower.

Warping to the main area of Lab 32

Once that flag is set, the entrance to the Lab 32 main area is activated. In Chrono trigger, most entrance never causes the fading out unless you move in there. That entrance, however, doesn't require such movement, and lets you go into the next area by just standing there. If you enter any location followed by a missing number, the game considers you are at (255,0), the right above place, which is in the entrance of Lab 32 main area. So the game immediately sends you into the main area.

There is another reason I had to use this trick: If you enter there followed by a normal character, Johnny tries to speak, but since he is outside the screen, he can't do it and the game freezes. Using this trick is the only way to avoid the freeze and advance the game.

Going through the barrier sprite

You can vertically go through the barrier sprite if it is outside the screen. To achieve this, you have to enter the room with a missing number in the first character. By this, the game considers you at (255,0) and then focus the camera on that point, which allows you to go through the barrier.

Alternatively, you can go through the barrier by using "Character sliding" trick instead. However, it requires one extra menu-opening, so I didn't use it, though I had no choice to use it when trapped out. Because this time it was required to move horizontally to go through the barrier.

Playing around with R-series

R-series bounce off only Crono. That means you can move around during the cutscene by fitting other character in the first, providing a second huge play-around time. It should be noted that Marle and Lucca won't do because they will take their regular position and just stand still. Like the Telepod area, this free-time is useful for shaving off frames. I did these two things for that purpose: 1) Erase the dialogue screen of R-series or Robo before they pop up by getting them out of the screen at the right timing. 2) Increments the moving counter of R-series by touching one of them at certain timing.

Normally, after Robo is knocked down, you become unable to move a character anymore. However, if you interrupt a fight with Alkalines just before losing control, R-series are also caught in the battle. This was supposed to be the fight with only Alkalines, so you can escape from them. Thus, you can gain control again. When the real R-series battle is about to start is the best timing you interrupt another Alkalines battle. With this, you can not only escape from them again, but also increments the storyline counter enough to open the door in Proto Dome.

Smoothly escaping

An escape counter builds up even when you open the technique or item menu in battle. The thing is, you can escape from a battle without being attacked by setting the battle mode "Wait", opening the either menu and holding the L+R buttons. This trick was featured in all the three battles in the Factory.

Robo repair skip

If you enter Proto Dome from overworld after the R-series fight, the game considers you just dragged Robo into, and make characters appear in front of the door for repair. That area is actually in warning area of the below enmies, so the characters start running down for fighting, though a fight starts halfway. When the fight finishes, you gain control and the repair cutscene never starts. At this point, the door to the gate room already opens; consequently, you can completely skip the Robo repair cutscene.

Also, when you enter Proto Dome, the first character must be Crono for these two reasons: 1) If you enter the gate room without Crono, the game freezes. 2) If a character is other than Crono, Marle, Lucca and Robo, he/she appears near the entrance, which doesn't awake the enmies and the game freezes.

Playing around at the End of Time

When you speak to snoring Gasper, you are given a few frames to move around until he starts talking. And if you take the opportunity of talking to Robo twice, you can avoid losing control. This is actually temporary, and you will lose control as usual after you skip the dialogue. However, if you check the healing bucket right after skipping the dialogue, three party characters get together and you can gain control again, providing a third huge play-around time. In the non-glitched run, the trick saves little time, only allowing you to get slightly faster to the point that Gasper shouts "Hey!" to Crono. In the glitched run, however, the trick serves as the set up to perform "Lavos Shell skip" more smoothly and dramatically. I'll pick it up later.

Confusing Spekkio

If you talk to Spekkio while you are still running around the room, he claims to do it over. However, if you continue and complete it keeping the dialogue screen open, he thinks it as succeeded. This doesn't save any frames, but I added it to the run because I felt it would slightly enhance the entertainment value.

Lavos Shell skip

This trick makes full use of the characteristics of gate transition as well as Middle Ages skip does. This is definitely the most difficult trick to pull off. Here are some important facts:

  1. In every gate transition, your starting X-Y coordinates in the next location is set a few frames before a fade-out completes.
  2. If you open the menu in that tiny window, you can overwrite them with the current X-Y coordinates.
  3. If your characters appear at (7-8, 0-8), the entrance into Lavos's body, in the day of Lavos, they immediately jump into Lavos's body. The reason is that the entrance has the same features as the Lab 32 one: Fade-out occurs by just being at the appropriate position.

The thing is, if you manage to open the menu at (7-8, 0-8) at the End of Time just before the fade-out to the day of Lavos completes, you can completely skip Shell Lavos. Normally, this is out of the question. In the first place, (7-8, 0-8) is outside the moveable area. Second, you lose control right after checking the bucket to the day of Lavos, which means you can neither move nor open the menu anymore. To solve this problem, I used the following glitches:

  1. If you run around the End of Time autofiring the A button with a dialogue screen opened, the second and third character eventually fall behind the first.
  2. If the two are too far behind the first, they stop catching up with the first and newly start it with reference to the position they stopped. Note: You need to use the trick "Playing around at the End of Time" to reproduce these two glitches in a timely manner.
  3. Hold two gate messages, choose yes for each. Then if the second message screen closes just before the rest characters, who run at the first to fly for the first gate waping, joins in him, you can restore the function to open the menu even while flying.
  4. Under these conditions, if you change the order of characters twice, you can get out of flying and freely move.

To pull off these four glitches are required to skip Shell Lavos. Here is what I did in the run:

First, use the "Playing around" trick and get the other characters out of the screen with the first and second glitch while Gasper gives the long speech. Second, replace the three characters with Ayla, Magus and $17 when Gasper finishes the speech. The reason I call out Magus and Ayla is they don't take any action when Spekkio tries to give Magic, which saves a few hundred frames. Although it's not visible, Lucca, the third character, is at (8,0) at this point. These coordinates values are stored in the proper addresses, which will be really helpful later. Third, enter Spekkio's room and acquire Magic from Spekkio, no one actually gets it though. Now the bucket to the day of Lavos is activated. Fourth, check the bucket so that the Gasper's warning message doesn't hinder the third and fourth glitches.

Fifth, talk to Gasper because it is needed to show his dialogue to hold more than one gate message. Sixth, hold the Proto gate message, which is the shortest one of the three, and check the bucket. Seventh, use the third and fourth glitches and get right to the save point. Since the Lavos gate message was the first, warping to the day of Lavos is going to occur at this point. It should be noted that (8,0) is still stored in the addresses because only the first and second character were swithced. Eighth, right after the starting X-Y coordinates in the day of Lavos is loaded, use the character warp trick, send the first character into (8,0) and save the game. The save point effect lasts for a few frames after you leave there, so that's no problem to save on that position. Now the save file includes the day of Lavos as the current location, and (8,0) as the current position. Finally, reset the game and load the save file. Magus appears at (8,0) in the day of Lavos. As I stated above, that position is in the entrance to Lavos's body. Therefore, the game sends him into the inner body in a blink.

Now we've done Lavos Shell skip!

It is extremely difficult to pull off, but the result is priceless. For the record, this is my favorite trick of all I have discovered.

Instant kill

Normally, when a character with the Green Dream is defeated, he automatically revives. However, when two RNG conditions are satisfied, the game temporarily considers him as dead. and if the other two characters are really dead at that point, he becomes unable to use an item on enemies instead of himself. If you use an Elixir on an enemy and the sum of its current HP and the HP heal is more than 32768(0x8000), that causes overflow and does instant kill. Inner Lavos has 20000 HP; Lavos Core has 30000 HP. Therefore, you can immediately finish those battles with the glitch. This is why I had to get a Green Dream and an Elixer from the configuration setting address.

Also, for some reason, the glitch never occurs if the character has any status effect such as protect or chaos on him/her. I guess this is why the trick had not discovered for a long time.

Useful key combinations

There are three useful key combinations to be mentioned:

X: If you press the X button in battle, you can point at an enemy as an attack target wherever the cursor is. This was helpful for targeting Lavos in using the instant kill glitch.

Start and Up/Down/L/R: Normally, you need 2 frames to move the cursor, as you have to insert null frame in each key press. However, if you press either the Up or Down key holding the start key, the cursor moves per one frame, which makes it possible very rapid cursor movements. The same goes for the L/R buttons. It normally requires 5 frames to scroll three pages; however, holding the start key reduces it to 4 frames. It should be noted, however, that it can be applied in only three places: the item inventory, the equipment selection screen, and the shopping window. In battle, for example, holding the start button will do nothing. This really comes in handy in a save-corruption run because you have to move up and down in the item inventory multiple times to perform the item duplication glitch properly.

B and Start: Once these two buttons are pressed in the pause menu or the character change menu, every frame is treated as the B button pressed until you leave the menu. Thus, you can immediately get out of the menu no matter where you are. Note that this is slightly faster than the normal method because it requires null frame in each B button presses.

About the movie

This is my second attempt at Chrono Trigger New Game+ run. It is 8661 frames (2 minutes and 24.35 seconds) faster than the previous one. The improvements came mostly from a new glitch that allows all characters to equip a Bronze Fist, but other minor timesaver was also found.

About the version change

I switched to the Japanese version because the glitch in the English version, unlike that in the Japanese version, doesn't allow any characters to equip a Bronze Fist. Bronze Fist deals 9999 damage on a critical hit regardless of enemy's defense. This means that there would be a significant delay on each boss fight in the English version. Even considering benefits from Japanese faster texts and taking them all away, the Japanese version will still be at least 1.5 minutes faster than the English version. More details about the glitch can be seen in the new tricks section.

About SRAM

In the previous run, I used Saturn's maxed-out save file that had been validated. This time, however, I needed to use my own save file because I decided to switch to the Japanese version as stated above. To clarify, I recorded the whole setting up process, starting from clear SRAM. I believe it would work as a good reference and verify the validity of the run.

New Tricks

In this section, I will describe new tricks I used in making the run. It should be noted, however, that all these tricks will not show up in the movie. They were performed only in the setting up process.

Loading a save file that shows "No Data"

By pressing A+Up/Down at the same time on the load screen, you can access a save file that says "No Data". Depending on SRAM conditions and the data selection mode, the following three cases are possible. If you use the trick:

  • Against a clear save file on the normal mode, the screen will black out and never recover.
  • Against a dirty save file on the normal mode or the new game+ mode, the previous save file will be loaded.
  • Against a clear save file on the new game+ mode, abnormal values will be loaded, and a new game+ will start.

The first is obviously useless. It may seem the second isn't of any use, but it was actually really important for the run, which will be taken up later. The third is the core of the trick; let us go into detail.

As with many other SNES games, at first 96 is stored in all SRAMs in Chrono Trigger. In the third case, 96 is stored in various memory addresses such as for the item inventory and character's stats, and then a new game+ starts. Naturally, that causes many strange things to the game, which is "the glitch" that I have called. I will list some glitch features that are strongly related to the run：

  • Every character can equip any equipment except for two kind of weapons.

There are important differences on equippable weapons between the (U) ROM and the (J) ROM (see list below). 

	equippable				non-equippable
(U)	Bow, Gun, Broadsword, Arm, Scythe	Sword, Fist
(J)	Sword, Gun, Broadsword, Fist, Scythe	Bow, Arm

As seen in the list, Fist type weapons, including Bronze Fist, are equippable only in the (J) ROM.

  • Almost all stats for every character are 96.

The only exceptions are speed, HP and MP. Speed is 16 because that is the limit value; HP and MP are 24672 because they are given two bytes. This feature makes it possible to get almost maxed-out stats for all characters without using any tabs.

  • Every character's techniques are limited.

Every character is allowed to use only the 2nd and 3rd single and dual techs. You can retrieve the 1st single tech of Crono, Marle, Lucca and Frog by having them meet Spekkio. However, there is no way to learn any other techs, since no enemies won't give Tech Points in a glitched data anymore.

  • A great deal of lag occurs during a battle.

Roughly estimated, the lag will make a battle 30% slower than a comparable battle in a normal data. Fortunately, that kind of lag can be completely avoided by keeping the item screen open.

  • Ayla's Bronze Fist doesn't appear.

Ayla's special ability, which automatically equips certain kind of fist depending on her level, is lost forever. Ayla's level is 96 in this case, so she should have a Bronze Fist, but the glitch doesn't allow it.

De-equip trick

In Chrono Trigger, you can change equipment, but cannot unequip it except when you are on the Blackbird. However, De-equip trick lets you do it anytime if certain conditions are met.

Requirement:

  • No equipment that the target character can change are in the item inventory.
    • To give an example, if you want to unequip Crono's Armor, you must sell out every armor that he can equip.

How to:

  1. Press L+down or R+up simultaneously on the equipment screen, and the previous character's equipment will be remained on the left screen. (It is required the cursor doesn't loop back in the key presses (by "the cursor doesn't loop back", I mean the cursor doesn't jump from the first character to the last and vice versa or from the weapon grid, which is located on the top, to the Accessory, which is located on the bottom and vice versa).)
  2. Press A, and a blank space will be called to the left.
  3. Press A again, and you can equip the character with "null"―unequip the character's equipment.

On a related note, the trick also has useful features other than the mere de-equip stuff. However, I won't go into further since it is not important for the new game+ TAS at all. For those who are interested in, check out this post.

Transferring items from one data to the other

If you reset the game one frame after you save a data, only SRAM for the item inventory and Crono's status is overwritten. As a result of reseting the game in the middle of save processing, a target data shows "No Data". However, as it turned out, now that you can restore a deleted data with the data selection trick, there is no problem.

Notes on SRAM overwritten:

  • Item ID is almost always overwritten; item number is overwritten only if the trick is used against a dirty save file. That means you can duplicate all items to 96 by using the trick against a clear save file.
  • Apparently Crono's status has a 70-80% chance of being overwritten.

Performing the tricks

So far I have discussed the new tricks. In this section, I will focus on how they were combined and performed in the setting up run.

First, I unequipped Ayla's Bronze Fist with de-equip trick on a normal data. Second, I transferred it to a clear save file. Luck was manipulated so that Crono's status wouldn't be overwritten, leading to only Item ID overwriting and item duplication. Finally, I pulled off the glitch, using Data selection trick (you might think the save file is not entirely clear at this point, but overwriting only item ID doesn't affect the glitch performance).

Thus I got the glitched save file in which has Bronze Fists, which can be seen at the beginning of the run. For possible reference, I will provide a demonstration movie, showcasing all the three tricks in a short length.

Note: Make sure that your Snes9x 1.51 is 5 or newer version before playing the movie; otherwise, the trick won't be reproduced properly and it will desync in the end.

Detailed commentary on the movie

In this section, I will give a full description on the movie place by place, especially for different parts from the previous run. Note, however, that I didn't pick up any frame gain/lose from:

  • Loading scene. This is highly rely on what emulator and ROM you are using. Since I used the different emulator and ROM from the previous run, it was very difficult to tell which was influencing on this. For ease of comparison, I decided to let it untouched.
  • Text scene. All through the run, Japanese faster texts were helpful in saving a frame. However, I didn't think that kind of improvement was a real one because it was done without putting any effort in, hence I excluded them from counting. For reference, I suppose the text differences would be around 1000 frames in total.

Load Screen

The only way to change a critical hit RNG in the first battle is to load a save file on a different timing. I load the save file 55 frames late. This is a huge delay, but there is no RNG that will make a critical hit happen on the best timing in every three battles before that timing. 50 frames lost (I had already delayed it by 5 frames in the previous run).

Battle mode screen I select Active. As I mentioned in the tricks section, you can reduce lag with the item screen opened. Wait is not suitable for this purpose, because it prevents the active bar from building up too.

Crono's name screen

I give Crono one-character name. The initial reason is that this is the Japanese version, and it was expected that most people here wouldn't care what he would be called in Japanese. I believe it wouldn't sacrifice any entertainment value. Since "Crono" is composed of three characters in Japanese, 2 frames will be cut off every time his name is called. 5 frames lost (but it will pay off little by little).

Lucca's name screen I keep Lucca's name as it is. Shortening her name doesn't save any frame because it will appear only twice in the run.

Leene Square

Put Crono in a better position when returning the pendant to Marle. 2 frames saved.

Marle's name screen

For the same reason as Crono, I give Marle single character name. 5 frames lost (but it will be rewarded eventually).

Shop screen

As usual, this is a good chance to change equipment with slight delay. Here are all equipment I give Crono and Marle:

  1. Bronze Fists to Crono and Marle to deal 9999 damage.
  2. Haste Helms to Crono and Marle to double their speed.
  3. A Berserker to Crono to get the best critical hit RNG at the end of Lavos Shell battle.

The first two will be self-explanatory; the last may sound a bit strange. In the Lavos Shell battle section, I will take it up in detail. 6 frames gained by less equipment change. 1 frame gained by pressing Up instead of B in getting out of the shop, eliminating a null frame. In total, 7 frames saved.\

Leene Square

Change the timing of entering into the area that sets the Candy cutscene, which allows you to pass the area without stopping. 5 frames saved.

Before Lavos Shell battle

Menu Entrance trick is used to change the battle speed to 2. That must be 2 because you cannot attack twice preceding the Hand Sickles of Inner Lavos at highest speed. In the previous run, I needed to set the menu cursor remaining function to reduce the amount of cursor movement. This time, however, I don't have to change anything except for the battle speed. 2 frames saved.

Lavos Shell battle

Weapon attack always increments the critical hit RNG for the next battle by 2; Berserker has additional increment before that process, which is depending on what an existing enemy's ID is. This additional increase is necessary to get the two critical hits in the Inner Lavos battle. This is why I gave the Berserker to Crono at the shop. Rapid cursor movement doesn't generate any lag in the battle, but affects the duration of screen transition. I will take it up in possible improvements section again. 1121 frames saved.

  • Strategy 
Character	Attack Type	Damage	Total Damage	Note
Crono		Normal hit	390	390		Lavos Shell has 10000 HP.
Crono		Critical hit	9999	10389		Fatal.

In the planning phase, I tried an alternative strategy:

  • Equip Marle with a Berserker as well. Marle's shot has shorter animation than Crono's critical hit. If it were done on a normal data, it would definitely be faster. In a glitched data, however, you cannot prevent lag from occurring with the item screen opend anymore. Because lag is too much, it would be slower in the end.

After Lavos Shell battle

I change Crono's accessory from Berserker to Bandana. I have to minimize the RNG increase in the next battle to get the best RNG for the Core battle, and thus Berserker's additional increment is not necessary anymore. In the previous run, I healed Crono's MP once. Changing one kind of equipment takes much time than using one item. 12 frames lost.

Inner Lavos battle

All thanks to Berserker's additional increment, I've got the favorable RNG, which not only arises critical hits in the first two blows, but also offers a RNG that is close to the best RNG in the Core battle. The fastest strategy is to use Crono's normal attack once and Marle's critical hit twice. However, I have to twist it a bit to get the exact target RNG. Here are two things I do:

  1. In Marle's first turn, Have her attack after Lavos uses "does nothing" action. - "Does nothing" action increments the RNG like your character's attack does, but the increment varies depending on what the current RNG is.
  2. In Crono's first turn, use Slash instead of weapon attack. - Slash always increases the RNG by 1 unless it is used at multi-enemies.

Slight delay happens due to those changes. However, Both are necessary to minimize the RNG increase and get the exact target RNG in the Core battle. 3396 frames saved.

  • Strategy 
Character	Attack Type	Damage	Total Damage	Note
Marle		Critical hit	9999	9999		The inner body has 20000 HP.
Crono		Slash		36	10035
Marle		Critical hit	9999	20034		Fatal. Once the inner body is dead, both arms also die.

Before Lavos Core battle

Unlike the previous run, Crono doesn't need any MP refill. All I have to do is enter and leave the status menu on the fastest timing. 57 frames saved.

Lavos Core battle

As a result of precise luck manipulation, I've realized a 1/256 chance of getting 3 critical hits out of the first 4 hits. This is the only RNG that allows you to sweep out all Lavos bits before they take any actions. I thus simply fire all the critical hits to the right bit. 3463 frames saved.

  • Strategy 
Character	Attack Type	Damage	Total Damage	Note
Crono		Critical hit	9999	9999		The right bit has 30000 HP.
Marle		Normal hit	29	10028
Crono		Critical hit	9999	20027
Marle		Critical hit	9999	30026		Fatal. Once the left bit is dead, the right and the center also dies.

Here is an alternative strategy that I tried in the planning phase:

  • Switch the roles of Crono and Marle. Crono's normal attack is faster than the critical hit; the aim is shorter animation again. Under this RNG, however, Marle always takes her turn following Crono. That means, you have to wait for her turn enables, move the cursor on her and attack. Unfortunately, the delay is enough for the right bit to interrupt the final blow. It is feasible if you set down the battle speed 3, but that will be slower in the end.

After Lavos Core battle

Apparently, if you beat the center bit before it uses Time Warp, Lavos roar happens rather late. It's ironic that the quick kill results in losing the time. 96 frames lost.

End of Time

When the door opens, I put Crono in a position where it is 4 pixels closer to the door, but still keeps the amount of scrolling unchanged. 2 frames saved.

Possible Improvements

The only thing I can think of is to reduce the duration of screen transitions. Although the duration is consistent in most cases, it varies between a couple of frames in a few cases, especially around the three Lavos battles. Considering that even one key press affects the duration, I think NMI might be related in that. Due to its randomness, I mildly optimized them in making the run. If they all were managed perfectly, I guess another 5-10 frames would be cut off. However, I'm not positive about restarting the run for only lag management, because no one can possibly detect it after all. Unless other timesaver is found, I will never pick up the run again.

Credits

First of all, I would like to thank everyone who has viewed and posted in the Chrono Trigger topic. Special thanks goes to Gocha for fixing the Snes9x bug that doesn't properly emulate the reset timing in playing back the movie.

I hope you enjoy the run!
