Monster Hunter 2 (Dos): matching the PS2 boot executable and overlays

Monster Hunter 2 (Dos) reconstructs the PS2 game's code as C and assembly for its original compiler. The author reports that the boot executable and twelve code overlays rebuild byte for byte, while licensed libraries and game data come from the user's version 1.04 copy. The repository also documents matching methods, function names and data structures.
