Biohazard Outbreak decomp: matching PS2 game reconstruction

Biohazard Outbreak decomp reconstructs C for the Japanese PS2 releases of Biohazard Outbreak and File 2, checking locally rebuilt executables and overlays against the originals. Its extraction, survey and function-comparison tools operate on user-supplied discs; the author reports 238 byte-matching File 1 functions, while File 2 C decompilation has not started.
