  "description_en": "A labeled and commented 6502 assembly listing reconstructs Space Jockey, US Games' first Atari 2600 game from 1982, and sets the TIA read base so it compiles to the exact 2K ROM image. An assembler switch selects NTSC or a PAL listing taken from the Carrere Video release, whose changes to vertical blank timing and colors are documented. Header notes discuss the origin of its horizontal positioning routine, and comments label obstacle attributes such as shot and firing flags.",
