[Release] Final Fantasy VII Script Code Assembler!

[titeguy3]

I got sick and tired of having to manually edit all of the Jump points in an AI Script after modifying something and having to frequently look up the hex values for stuff, so I decided to write myself a little Assembler so that I can code directly in assembly and use labels and quantifiers instead of having to put in raw hex values.

It's nothing flashy, but it works pretty well. I've tested it against Sephiroth's Pre-Battle script and it matched perfectly.

Here's what the input file looked like:

Code: [Select]

; Sepher Sephiroth's Pre-Battle AI Script;Label Opcode Argument  PUSH12 Self ;This is a quantifier, There's a total of 124 of them built in. Typing "self" is the same as 2060 PUSH10 402C MASK PUSH01 01 STRA PUSH 00 PUSH02 0268 GLOB PUSH13 0020 PSHA01 GlobalAddress ;This is another one, this one stands for x2010 STRA PUSH01 00 PUSH01 5B GLOB PUSH13 0040 PSHA01 GlobalAddress STRA PUSH01 00 PUSH02 026C GLOB PSHA01 GlobalAddress PUSH01 01 EQU JMP0 jump1 ;This is a Label, it stores the address of any other instruction, so long as it's labeled with an identical label PUSH13 0060 PUSH03 013880 ;Note: when dealing with PUSH and PSHA, specifying a type (e.g. PUSH03) is optional--PSHA defaults to PSHA00, and PUSH defaults to opcodes 60, 61, or 62 depending on the argument size.

And this was the output file:

Code: [Select]

You can see a screenshot of it in action here:

Told ya, the interface isn't exactly flashy but it gets the job done.

You can download it and try it out here

If you find any bugs, be sure to tell me, send me a screenshot or a copy of the error message and the input file and I'll try to fix it and get another version up.

Edit: FF7 Script Code Assembler is now v1.1! The max number of labels allowed is now 50 (from 10) and it no longer crashes when you exceed that. Note also that the max label size is 15 characters. The TBIT opcode has also been fixed.

Is this for script for PC version? i'm hoping for a psx enemy script

 

[Kudistos Megistos]

I haven't tried it, but since the scene.bin is the same in both versions of the game maybe this will work with both?

 

[titeguy3]

It just spits out a .txt file with the hex values for the script, which are gonna be the same between pc and psx.

I admit that this would be a ton more useful if you could just copy and paste tabbed entries into proudclod.
