xmen2disasm: rebuilding X-Men 2 from a matching disassembly

xmen2disasm reconstructs the Sega Genesis game X-Men 2: Clone Wars as a byte-matching 68000 disassembly. Its build reads data from the user's ROM, and emulator traces support function boundaries, labels and coverage checks. The author reports a byte-identical ROM rebuild; the related C reconstruction and native PC port reside in xmen2-pc.
