Ratchet & Clank Decompilation

About

A work-in-progress matching decompilation of Ratchet & Clank (Insomniac Games, 2002) for the PlayStation 2, targeting the PAL v2.00 executable SCES_509.16, as part of the OpenRAC initiative. The aim is C/C++ source that, built with the original toolchain, produces a byte-identical copy of the retail executable, which is then refactored toward readable C++.

Getting started

The repository contains no game assets, retail executables or disassembly, so you must provide your own legally obtained copy of the game. Copy SCES_509.16 from your disc image into the baserom folder, install dependencies and toolchains, and run the build script. Linux and macOS builds use a Docker or Podman container; Windows uses Git Bash and Python 3.10+.
