reDM2: reconstructing Dungeon Master II in C

reDM2 reconstructs the DOS release of Dungeon Master II in C from its shipped SKULL.EXE executable. It separates game code from linked libraries and compares ported functions with the originals using Unicorn emulation, memory-write checks, and captured game-state snapshots. The author reports that some functions remain blocked by missing emulator capabilities.
