A work-in-progress decompilation of PaRappa the Rapper 2 (パラッパラッパー2) for the PlayStation 2.
We are currently targeting the July 12th NTSC-J prototype, but we aim to target the final NTSC-J/NTSC/PAL builds in the foreseeable future.

Requirements setup

  1. sudo apt install gcc-mipsel-linux-gnu binutils-mips-linux-gnu ninja-build
  2. sudo apt install python3-pip
  3. python3 -m pip install -U -r requirements.txt

Note: For compiling, you need to add the i386 architecture. For instructions on that please check out this guide if you're on Ubuntu.

Setup

  1. Create a folder named iso in the root of the repo.
  2. Extract SCPS_150.17 from an ISO of the July 12th prototype and place it in said iso folder.
  3. ./configure.py (use -c to do a clean split.)
  4. ninja

asm-differ setup

  1. After a successful build, create a folder named expected
  2. Copy the build folder inside the expected folder.
  3. ./tools/diff.py -mwo FUNCTION_NAME

Note: Every time you add a new symbol, you must do the asm-differ setup again.
