Tech Editor - Period

[FaustWolf]

Ooh! Ooh! Ozzie! You're getting into stuff justin3009 explored earlier, so you might be able to fill in the gaps in our knowledge here:
http://www.chronocompendium.com/Term/Tech_Data_Notes.html

Look under "Offsets Pertinent to Techs"

You can list your findings here and I or someone else with access could put them in the wiki or something. I think, within our framework...

0x0D45AD ~ 0x0D4925: Unknown tech data; 7 bytes each (127 techs). May point to graphics and sound data.
 The bytes are structured as follows: aa bb cc dd ee ff gg
  aa = An unknown tech index. May point to two-byte "slots" beginning at address 0x0D5EF0
  bb =
  cc =
  dd =
  ee =
  ff =
  gg =

...you've found that dd = palette index, is that correct? Awesome work. We may as well get these seven functions filled in while you're at it. Also, let us know what mistakes are in the wiki as you find them.

Man, I can't wait to see Magus use Lightning1, Fire1, and Ice1. Just because. Or maybe, with control over palette and strength data, "PhantomBolt"...

Just out of curiosity Ozzie, what value did you use for "dd" in the above framework to get that nice purplish sword slashy effect? We can put a list of values in the wiki as well for each byte.

[Ozzie]

One byte off eh? Looks like someone else already documented some of this stuff.
If nothing else, I narrowed it down, and specified a breakpoint for easy listings.
I suck at wikis, so anyone can feel free to replicate any findings I make here in it.

[Ozzie]

I used '09' I think to get the nice purple. Some palettes look horrid of course, but still, this means that any graphic, any size, and colors can be used now in conjunction with jsondag's awesome tech editing program, for pretty much complete custom techs.

The breakpoint I supplied earlier only seems to apply to player techs, some of the early enemy techs I've run across have failed to trigger it, but that's ok, the editor only edits player techs for now anyway.

[FaustWolf]

I might be the one who's a byte off for all I know. I was just looking at the hex in the ROM when I compiled the "offsets pertinent to techs" stuff from everyone else's findings back in January. Please continue your work -- I certainly haven't had any time to sit down and document our understanding of this section of the CT tech data yet, and I believe it is crucially important. Justin3009 left additional notes that I haven't transcribed yet as well; I'll point you to there if I can dig them up from the forums.

It would be a *huge* help if you could find out what each byte does in the range 0x0D45AD ~ 0x0D45B4 (that should be the range for Crono's Cyclone tech), and catch any mistakes we made in the description that's currently up.

Anyway, welcome to the Compendium! Expanding technical knowledge of the games is a great way to make a start!

EDIT: Ozzie, I have a hypothesis that jsondag2's working directly with the raw tech data and the range you've been looking at most recently contains pointers to that raw data; they might be like mid-level pointers to stuff further down in the ROM. This may not be correct, however; 'tis only a guess on my part.

You are correct, it seems to be 7 bytes, not 6. That'l learn me to dissasemble stuff after just waking up. 

[Agent 12]

I'm adding in all the tech data from the D5XXX range as we speak look for an update later today 

This is good stuff, if we can edit this reliably it's a major milestone.  Faustwolf I'm pretty sure your hypothesis is correct.  My data edits ONLY the animations and sounds the exact same data for fire and lightning can be put in my editor and different graphics be loaded so the graphics is coming from somewhere else and it seems like we've found out where.

Ozzie, you are making quite an entrance to Kajar labs.  The compendium is on a war path right now welcome to the party.

[Ozzie]

Can you use the debugger to get the addresses you need to edit the 7byte graphics data?
If not, I can download a save game and go through and make a list of offsets for you to plug into your editor, and then label each field as they are deciphered down the road.

[Ozzie]

Updating with offsets, refresh occasionally for more.

I'm pretty sure I got all the offsets already....

Are we sure it's 7 bytes for every single one though?

I got 7 bytes for some of the but 6 bytes for others?

Edit:  Actually I guess that would be pretty stupid huh.......i'll change it to 7 bytes each and then add an update to the front link...... (There seems to be some that like ....don't end in FF and I counted those as 7 bytes and the ones surrounded by FF i was counting as 6 bytes)

--JP

[Ozzie]

I'm guessing FF is like "NULL" or nothing for that graphic's property. Some graphics have animation, some do not, some glow, etc.

This saves me some time if you have the offsets already...


You know how some techs disable layer 3 (fog and stuff) to execute? I wonder if one of the unknowns is disable, enable layer 3? That's been bugging me, I dont' think all techs disable layer 3, just the ones that require translucency. I should look into that eventually too. [/random thought]

[FaustWolf]

jsondag2, I can confirm that the seven-byte pattern still holds at the end of the range 0x0D45AD ~ 0x0D4925

If you take 0x0D4926 and subtract 0x0D45AD, you get 0x379 or dec 889, enough for 7 bytes for 127, or 0x7F techs.

Note that there are up to 0x7F player techs in our tech list in the wiki. However, there is room for error since we haven't identified what all the techs are yet -- there seems to be some dummy techs at the end of the list. Also, there may be a dummy tech that precedes Cyclone. Given that the 7-byte pattern holds at the beginning of the range and the end of the range, I am strongly inclined to say that it's seven bytes of hex data per tech in the ROM, but the end FF byte might just be a separator and not an active pointer.

[Ozzie]

Given that Cyclone is the second tech in the 7byte graphics table, I wonder if the first tech is dummied?

Always wondered if there were dummied out techs...

[FaustWolf]

justin3009 would know more about dummied techs than I; there may have been several if memory serves.

EDIT: Ah! In light of your update jsondag2, I guess we do know that the seventh FF byte that appears in most(?) techs is just buffer data to maintain a 7-byte stride.

[Agent 12]

Alrighty, update is out (front page link)

Obviously this is a very fast update so you may want to do some confirming of your own....or you can just trust my greatness  .

Load up the Rom and the tech and go to View-> Properties.

There's a fancy new "Graphics" section with the 7 bytes of from the D5 XXXX range.  I know this MIGHT not be solely graphics but i'm excited enough for now that I'm calling it graphics.


Most of them are unknown the only ones that are not are "tech index" which i think is the index of what animations etc to load (liek just said change Ice's 0C to 01 and it does cyclone?"  (Faustwolf this is the part that I was talking about earlier that points to my stuff). 

I also put in pallete since Ozzie seems to have confirmed that (we should do more testing on it though).

One of the annoying things about this is that it put them out of order since it sorts them alphabetically, I'll append the byte number later.  If you want to see them in order use the fancy new copy graphics hex button that I added on the right, it copies it to your clipboard so you can paste it in notepad or whatever. 

Using  that copy button it shouldn't take long to document these things and find some patterns.

--JP

[Agent 12]

Here is the data excel sheet where Tech editor is grabbing it's data from... i suppose I should put this on a wiki somewhere eventually:  note that it's tab delimited and in decimal (cause in my code it's not taking hex indexes)

I've copied the D5 XXXX raw data up through lucca's flare if someone wants to finish the job and look for more patterns.
