About

Galaga is a 1980s Namco arcade game, whose original Z80 program code this project reconstructs from disassembly. This project provides commented, compilable Z80 assembly source that reconstructs Galaga's original arcade ROM code from disassembly, rather than reimplementing the game's logic independently. Assembling it and combining the output with the original Namco graphics, palette and lookup ROM binaries (not included) reproduces the original program ROMs, which can be checksum-verified against the real game in the MAME emulator.

Getting started

You need your own dumped Namco Galaga ROM graphics, palette and lookup binaries (not included), plus the required assembler toolchain, to assemble the source into ROM images that can then be run and checksum-verified in the MAME arcade emulator.

Requires original assets. Requires binary files from Namco arcade game (multiple .bin ROM files) to build and run.

Additional notes

Compatibility: The build requires an older release (5.10) of the asxxxx assembler; newer versions of that assembler are currently known to break the build.
