  "description_en": "Berzerk for the Atari 2600 (Atari, 1982) is reconstructed as a labeled, commented 6502 assembly listing that assembles to the exact original ROM image, with a switch for the NTSC or PAL build. The notes cover the game's sprite-drawing technique, PAL frame-delay values set at 1.2 times the NTSC ones, unused diagonal robot-fire values left in the ROM, unused RAM and the roughly 12-second launch of Evil Otto.",
  "description_zh": "将 Atari 1982 年发行的 Atari 2600 游戏 Berzerk 整理为带标签和注释的 6502 汇编清单，可汇编出与原版完全一致的 ROM 映像，并可通过开关选择 NTSC 或 PAL 版本。注释说明了游戏的精灵绘制方式、PAL 版帧延迟取 NTSC 值的 1.2 倍、ROM 中残留但未使用的机器人斜向射击数值、未使用的 RAM，以及 Evil Otto 约 12 秒后出场的时机。",
