Usage

./gsc-tool.exe <mode> <game> <path>

modes: asm, disasm, comp, decomp

games: iw5, iw6, iw7, iw8, s1, s2, s4, h1, h2, t6

paths: file, directory (recursive process all files inside dir)

for zonetool files (.cgsc, .cgsc.stack) use: zasm, zdisasm, zcomp, zdecomp modes

Mode Description Output
asm assemble a file.gscasm file.gscbin
disasm dissasemble a file.gscbin file.gscasm
comp compile a file.gsc file.gscbin
decomp decompile a file.gscbin file.gsc

File Format

If you need to extract scripts from fastfiles or game memory, use Zonetool or Jekyll.

  • gsc-tool .gscbin format is a serialized ScriptFile struct: name: null-term string, compressedLen: 4 byte uint, len: 4 byte uint, bytecodeLen: 4 byte uint, buffer: byte array[compressedLen], bytecode: byte array[bytecodeLen].

  • zonetool (IW5) format made of bytecode file .cgsc and decompressed stack buffer .cgsc.stack.

  • treyarch (T6) format is a single buffer with gscobj data .gsc or .csc.
