Indy 500: a first-pass labeled Atari 2600 disassembly

Indy 500 for the Atari 2600 is disassembled with DiStella v3.0 into a 6502 listing carrying a first pass of hand-written labels and comments. Named RAM locations cover game state, scores, speed settings, car positions, collision state and audio channels, and comments mark the mirror-symmetrical racetrack kernel, acceleration handling for both cars and per-game color-palette tables.
