# FreQuency: reconstructed PlayStation 2 source and runtime

> FreQuency reconstructs source and runtime components for the 2001 PlayStation 2 rhythm game. Its build uses ps2dev compilers for the Emotion Engine and IOP, reconstructed Sony library routines, and an optional user-supplied disc image to create a Mode 2 CD image with rebuilt executable and EZMIDI.IRX files.
