Mega Man 3: an annotated ca65 NES disassembly

Mega Man 3 reconstructs the US NES game as annotated ca65 assembly across its code banks. The repository also documents the frame loop, entity logic, collision, MMC3 bank switching and data table formats. Its build produces a ROM that the author reports matches the original byte for byte.
