It organizes modules by subsystem, models selected game data formats, and checks rebuilt ROMs byte for byte against the user's own images; the author also reports MAME runtime comparisons.",
  "description_zh": "Sonic the Hedgehog 2 Source Reconstruction 以 Sonic Retro 的反汇编项目为基础，将 REV00 和 REV01 零售版整理为共用的 68000 与 Z80 源码。项目按子系统组织模块、建立部分游戏数据格式模型，并将重建 ROM 与用户自备映像逐字节比较；作者还报告了 MAME 运行对比。",
