About

A disassembly of the NES game Mega Man 4 (NTSC-U) whose code and data are 100% finished and which assembles to a clean ROM under xkas-plus. It covers a game that uses the MMC3 mapper with 64 PRG banks of $2000 bytes, with most code banks bundled into one file. A Windows build of the assembler is included in the repository, and not all code is documented yet.

Getting started

Run the included xkas assembler on the main assembly file with an output ROM name to produce the ROM.
