# Splashdown: a matching PS2 decompilation and Linux port

> Splashdown reconstructs C++ source for the NTSC-U PlayStation 2 game and builds a native Linux x86-64 port from it. The project checks reconstructed functions and the linked executable against retail bytes and a SHA-1 hash. The author reports that all 4,356 game functions match and that the Linux port plays the full game at 30 FPS.

## Requirements & limits

- Supply your own Splashdown dump, including its retail executable and, for the port, a disc image.
- The matching build uses Metrowerks mwccps2 2.4, wibo, splat, and MIPS GNU binutils; the Linux port uses clang, SDL3, and zlib.
