Digimon World 3 Decompilation

About

A work-in-progress matching decompilation of Digimon World 3 for the PlayStation: C source that compiles into byte-identical copies of the game's executable, overlays and stages. The European release (SLES_039.36) is the main version and the USA release (SLUS_014.36) builds from the same C. Overall, 3,604 of 3,606 functions are in C for Europe and 3,378 of 3,380 for the USA, with two overlay functions left in assembly. The repository contains no game data.

Getting started

You need your own copy of the game: extract each disc with the included extraction tool into its own disks folder and check the executable's SHA-1. On Debian or Ubuntu, install the MIPS binutils and Python, clone with submodules, then run make to generate, build and compare; a Docker build environment is also provided.

What you need to run it

Modding & tools

• The build uses GCC 2.8.1 for the PlayStation.
