Evo's Space Adventure Decompilation

DecompilationSporadic

Source code reconstructed from the original game's compiled binary, so the game can be understood, rebuilt and ported.

About

A proof-of-concept, work-in-progress decompilation of Evo's Space Adventure for the PlayStation 1. It uses gcc 2.92.2, GNU as and maspsx to build a matching binary without the PSYQ toolchain, and is meant to be built on Ubuntu 22.04, natively, via WSL2 or via Docker.

How it differs from the original

The README says the PSX port is a much more basic version of the game, with a lot of the functionality stripped away compared to the N64 version.

Getting started

You must already own a copy of the game. Copy the esa.dat file from your game CD-ROM into the root of the cloned repository, extract and disassemble it with make extract, then compile it back with make all.

Additional notes

Purpose: The project exists to show that a PSX decompilation can be accelerated with tools built for N64 decomp projects, and to help the existing Space Station Silicon Valley decompilation.
Shared code: Large chunks of code were copied from the N64 version of the game and the PSX port, and files are named after their Space Station Silicon Valley counterparts.
