Monster Hunter: matching decompilation of the Japanese PS2 release

This repository decompiles the first Japanese PlayStation 2 release of Monster Hunter. The disc files are SLPM_654.95 and AFS_DATA. A successful build compares the ELF and overlays byte for byte. The README says the main ELF still has a few mismatches and overlay matching is currently turned off.
