A work-in-progress, byte-matching decompilation of Ratchet & Clank (2002) for PlayStation 2.
Reconstructing the original game code in readable C, with a native Rust port as the long-term goal.
Note
Yes, this project is AI-driven— that’s pretty obvious...
While AI does the heavy lifting, I maintain full control over architecture, tooling choices,
and overall direction, with every single PR manually reviewed and verified before merging.
Warning
Lombyte does not include game data, executables, disc images, or proprietary toolchains.
A legitimately obtained copy of the USA / NTSC-U release (SCUS_971.99) is required.
| Game | Platform | Region | Boot executable |
|---|---|---|---|
| Ratchet & Clank (2002) | PlayStation 2 | USA / NTSC-U | SCUS_971.99 |
Expected SHA-256 of the boot executable:

Only this release is currently targeted. PAL, NTSC-J, and the PlayStation 3 remaster are not supported.
Contributions to matching C, recovered names, types, and documentation are welcome. See CONTRIBUTING.md for the workflow and verification requirements.

- splat and spimdisasm — executable splitting and disassembly.
- Himuro — PS2 decompilation research and reference EE-GCC toolchain work used by Lombyte's matching compiler profiles.
- bordplate/RC1 & Lynder063/rac1-decomp — used as a reference for symbols, structs, and function logic (credited inline in the source).
- The PS2 reverse-engineering and decompilation communities for the tools and research that make matching projects possible.
