Outlaw: a reverse-engineered Atari 2600 source listing

Outlaw for the Atari 2600 (Atari, 1978) is reverse-engineered into commented 6502 source that compiles with DASM. Named RAM variables cover the playfield arrays, scores, bullets in each gun, sound state and obstacle positions, and the commented code walks through the score and magazine display, the main four-line display kernel, gun reloading, select handling, movement and bullet bouncing.
