# PES6 decompilation: matching the PS2 PAL executable and overlays

> PES6 decompilation reconstructs C source for the PlayStation 2 PAL release of Pro Evolution Soccer 6, covering its resident executable, 26 executable overlays and an auxiliary ELF. Local builds compare recovered functions with the user's game inputs; the author reports 10,930 exact function matches and separately tracks provisional nonmatching C.
