  "description_en": "Venture for the Atari 2600 (Coleco) is reverse-engineered into commented 6502 source with a DASM build command that writes a listing, symbol table and binary. Comments document the screen region used for rooms, sprite timesharing in the moving-wall room, monster status values, shot range, collision handling and per-room playfield offsets, and every graphics table carries a visual comment of its pixels; two RAM bytes are marked unused by the original code.",
