Castlevania: Symphony of the Night disassembly

Recompilable code that creates 1:1 binaries for the commercial videogame Castlevania: Symphony of the Night for the PlayStation 1. This repository aims to create a full decompilation in C.

Game revision

SHA-1 checksum File name Version Progress

Build

  1. You need gcc-mipsel-linux-gnu that you can easily install on any Debian-based Linux distribution. On Windows it is highly recommended to just use Ubuntu with WSL
  2. Place your main.exe from the file SLUS_000.67 and DRA.BIN in the root directory
  3. Run make extract to generate the assembly files
  4. Run make all to compile the binaries into the build/ directory

Notes

  • I suspect that GCC 2.7.2 / PSY-Q 3.6 have been used to originally compile DRA.BIN
  • main.exe uses PS-X libraries that might've been created with a different compiler and with -O1 rather than -O2

To do

The project is very barebone at the moment and there is a massive room of improvement, mostly in the infrastructure:

  • The zone overlays (ST/{ZONE}/{ZONE}.BIN) are not yet disassembled
  • The progress badge is not automatically updated by a CI/CD pipeline
  • There is no CI/CD pipeline to test the correctness of the compiled code
