About

A decompilation project for the PSX port of pop'n music, listed as pop'n music CS. The README says it is at an early stage and tracks progress on the full game executable SLPM_861.83.

Getting started

You must provide your own dump of the retail game (a .BIN, renamed popn.bin) and run make teariso to extract the original executable, which is used as a reference. Building needs git, cmake, build-essential, MIPS binutils and cpp, and Python 3 with a virtual environment, on Linux, or on Windows via WSL.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game.
