Example: ./gsc-tool.exe comp iw5 pc ./data/iw5/my_fancy_script.gsc
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 |
parse |
parse a file.gsc |
file.gsc |
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-terminated string
compressedLen: 4 byte uint
len: 4 byte uint
bytecodeLen: 4 byte uint
buffer: byte array[compressedLen]
bytecode: byte array[bytecodeLen]
note: for PS3 & Xbox 360 .gscbin
files (compressedLen, len, bytecodeLen) are saved as little-endian!!
-
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
.
If you like my work, consider sponsoring/donating! Would allow me to spend more time adding new features & fixing bugs.
