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-assisted—that’s pretty obvious.
AI helps get more done, but the direction and decisions remain human.
A lot of time and care goes into getting things right. Every PR and issue is manually reviewed.
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 |

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.
