# Starmaster: a commented Atari 2600 disassembly

> Starmaster for the Atari 2600 (Activision, 1982) is disassembled with DiStella v2.0 and then analyzed, named and commented into readable 6502 source. Named constants describe the 6x6 sector map, starbases, enemy IDs, star field, warp and laser timing and enemy fire distance, and an OPTIMIZE switch swaps in code improvements the author identified while studying the routines.
