  "description_en": "A labeled and commented 6502 assembly listing reconstructs Kaboom!, Activision's 1981 paddle game for the Atari 2600, as a 2K ROM source on the MiniDig disassembly page. Assembler switches select NTSC or PAL timing and colors and choose between the original back-and-forth Mad Bomber movement and a smooth variant. Labeled constants cover paddle limits, bomb-group sizes and the display kernels, and comments note bomb-group table entries the game never reads.",
