Example: ``gsc-tool -m comp -g iw5 -s 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` | ## File Format If you need to extract scripts from fastfiles or game memory, use [Zonetool](https://github.com/ZoneTool/zonetool) or [Jekyll](https://github.com/EthanC/Jekyll). - gsc-tool `.gscbin` binary format is a serialized ScriptFile struct: <br/> - ***magic***: `"GSC\0"` 4 byte <br/> - ***compressedLen***: 4 byte usigned integer <br/> - ***len***: 4 byte usigned integer <br/> - ***bytecodeLen***: 4 byte usigned integer <br/> - ***buffer***: byte array[compressedLen] <br/> - ***bytecode***: byte array[bytecodeLen] <br/> 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`. ## Build - install [*premake5*](https://premake.github.io) on your system PATH - clone this repository - update the submodules ``git submodule update --init --recursive`` - run prebuild script ``premake5 vs2022`` (windows) or ``premake5 gmake2`` (linux/macos) ## Contribute If you like my work, consider sponsoring/donating!
