Banjo-Kazooie XBLA decompilation project

A research project to decompile the XBLA version of Banjo-Kazooie with help from (looking at the code of) the N64 decompilation project.

Some code, like enumerations or structure definitions, are taken from the N64 project.

Requirements

  • split360 and coff-linker in the PATH.
  • Visual Studio 2005 SP1 installed.
  • XBOX 360 SDK installed (I'm using 7645).
  • Editing tools/vs2005.bat to change XEDK to the correct path.
  • Python
  • GCC for PowerPC (e.g. powerpc64-linux-gnu-*). Need to edit tools/matcher.py if different.
  • WINE installed if building on linux.
  • Editing Makefile to remove the call to WINE if building on Windows (untested).

Optional: you can add dump-diff to your PATH if you want to print the non-matching differences.

Usage

You need to have an uncrypted default.xex from Banjo-Kazooie (sha1: 24f81f8058d1be416d95ccfcb5ebd2503eb4fd47) at the root of the project.

Look at the Makefile to see what you can do. But basically, you do make split the first time (and each time you edit bk.yaml), then just make to regenerate merged.xex.

Objdiff

There is objdiff support. You just need to make objdiff to generate objdiff.json.

⚠️ Since the code is compiled with MSVC but checked against code assembled by GCC, relocations (i.e. function calls) will show as different

Current state

Copying functions from the Ghidra pseudo-code or from the N64 decompilation project and see if they match.
