CHRONO CROSS ROOM SCRIPT INVESTIGATION THREAD (formerly event script thread)

[yaz0r]

I'll give it a try when I get home, but I don't have much hopes.

Tried all the characters and as expected, only the one actualy present in the demo work.

[yaz0r]

Here is the walkmesh for the first room of CC (the elevator room).

[FaustWolf]

Oh maaan, this is awesome yaz0r. Which file number is it that contains the walkmesh again? Is it definitely 0004.OUT?

[yaz0r]

It's the 0004.out and 0005.out.
0004 is the triangle setup, and 0005 is the vertice array.

Here is a quick and dirty code that export a walkmesh to obj.

[utunnels]

Ho, I didn't ask for that
It's just the lack of feedback I was having on the thread let me thing that only I cared for this stuff

Anyway, here is a slightly updated source that should fix the badly decoded opcodes because of the garbage byte (that may be some actual data inlined in the script, I don't know yet).
I haven't tested the new code very much, but it seems to be giving some results. I also worked a bit on the assembly to get more information about the scripting engine.

Hmm, I tried your decompiler today, but I got something like this:

---------------------------
| Entity 1 script 5
---------------------------
0x00CB: op43(0x001100, -880, var[0xFFFFF0C0], 240)
0x00D4: STOP()


What is var[0xFFFFF0C0] supposed to be?



I tried Luccia's room.
It seems this script is used for displaying Lucca's letter:

---------------------------
| Entity 25 script 4
---------------------------
0x0B50: PLAY_SONG(21) // The Girl Who Stole the Stars
0x0B53: op8A() // wait something
0x0B54: op68(0, 0, 0, 60, 60) // screen fade or blink, not sure
0x0B5F: WAIT(60)
0x0B62: op62(165, 100, 0, 0, 820)
0x0B6D: DIALOG(0x0037, 0x00)  // My dear Kid, How are you doing?
0x0B71: WAIT_DIALOG()
0x0B72: DIALOG(0x0038, 0x00)
0x0B76: WAIT_DIALOG()
0x0B77: DIALOG(0x0039, 0x00)

0x0B9F: DIALOG(0x0041, 0x00)
0x0BA3: WAIT_DIALOG()
0x0BA4: DIALOG(0x0042, 0x00)
0x0BA8: WAIT_DIALOG()

0x0BC5: DIALOG(0x0048, 0x00)
0x0BC9: WAIT_DIALOG()
0x0BCA: DIALOG(0x0049, 0x00)
0x0BCE: WAIT_DIALOG()
0x0BCF: DIALOG(0x004A, 0x00)
0x0BD3: WAIT_DIALOG()
0x0BD4: DIALOG(0x004B, 0x00)
0x0BD8: WAIT_DIALOG()
0x0BD9: WAIT(60)
0x0BDC: DIALOG(0x004C, 0x00)
0x0BE0: WAIT_DIALOG()
0x0BE1: WAIT(30)
0x0BE4: opFE1D(180, 0)
0x0BEA: op68(0, 0, 0, 0, 60)
0x0BF5: STOP()



This script has something to do with the ghost shadow.
Because if I replace it with a dialgue, the shadow just won't show up.

---------------------------
| Entity 24 script 4
---------------------------
0x0B19: op34(0x00)
0x0B1B: opFE47(3000, 2000, 0)
0x0B24: Unk opcode 0x94



Hmm, it seems that's the letter Luccia gives to Kid.

[yaz0r]

Can you give me the room numbers you've been working on ? Especialy for the first issue you mentioned (0xFFFFF0C0 means that it's a negative value, that should not be possible).

[utunnels]

I copied the decompressed script from memory.
How can I know the room number anyway?

[Vehek]

We have this list
It's room 193 on that list.
(Both versions of the treasury also contain Luccia's lab, set parameter to 01 to go to the lab part).

[FaustWolf]

We also have a list in terms of .OUT files if that's helpful.

[utunnels]

Yeah, that script is for both the treasury and the lab.
If you let the game load Grobyc's model instead of the letter's, Luccia will hold mini Grobyc in her hand when you talk to her.

We have this list
It's room 193 on that list.

Ah, so there's aleady a room jump cheat.

I wonder why all those crashed for ZeaLitY? utunnels, are you going through the Debug menu too, or are you basing this on investigating the raw data? I'll update these on the main file structure page and the Room Files subpage soon.

[utunnels]

I think he only used disc1?

Oh, I used the cheat code instead of debug menu.

[ZeaLitY]

Yep, Disc 1.

[yaz0r]

I'm modifying the dumper so it can dump the scripts from the whole game in one pass. Also, I'll try to include the dialogue in the script disassembly so it's easier to figure out what the script is doing without having to check the dialog text every time.

I remember that some of the room on disk2 (especialy the developper ending room) overlaps regular rooms on disk1 (ie, they share the same room numbers). I may be wrong, but if I'm not, it means it's not possible to have a global list of rooms that work for both disk1 and 2.

You are probably right, because when I checked those rooms that are not listed, I didn't find the rooms for the developers ending...
Or perhaps they are just regular rooms with different script conditions?
