CMOS Galaksija
The incomplete Galaksija ROM disassembly
This is an assembly source file automatically generated from binary ROM image with z80dasm. Human-readable comments were gradually added later by me while working on a modern CMOS replica of Galaksija (with the wonderful Incomplete Spectrum ROM Assembly as a style guide).
This source can be assembled into a binary identical to the original ROM image with a Z80 assembler like z80asm.
