- **IW6** *(Call of Duty: Ghosts)*
- **IW7** *(Call of Duty: Infinite Warfare)*
- **IW8** *(Call of Duty: Modern Warfare (2019))*

## 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](https://github.com/ZoneTool/zonetool) or [Jekyll](https://github.com/EthanC/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``.
