A 100% byte-matching decompilation of Monster Hunter 2 (Dos) for the PS2.
Matching decompilation of Monster Hunter 2 (Dos), NTSC-J v1.04: per the README all 12,551 of Capcom's functions are C or assembly that rebuild the boot executable and all 12 overlays byte for byte, checked against SHA-1s, while Sony, CRI and other licensed libraries come from your copy as assembly. Builds on Linux or WSL from your own disc. The README says it was made almost entirely by Claude (Opus 5.5) in Claude Code.
