# Rayman: matching decompilation of the PAL PS2 main executable

> This project decompiles the PAL PlayStation 2 Rayman main executable, SLES_500.44, into C and hand-written assembly. Its build links an ELF at the original addresses and compares the main image and individual functions byte for byte with a locally supplied reference. The author reports 856 of 5,645 functions matching.
