    "Native ports target macOS, Windows and Linux. Playing and checking against the originals requires your own matching game files (the README targets GOG releases); byte-matching builds additionally require the documented Turbo C++ 1.01 and TASM 2.0 inputs. Native-port compilation itself does not require game data.",
    "The MIT license covers the project’s own tools, documentation and added annotations/structure. NOTICE explicitly excludes rights in the original games and derived game code; optional MT-32 playback requires separately obtained ROMs.",

    "原生移植面向 macOS、Windows 与 Linux。运行及对照原版检查需要自备匹配的游戏文件（README 面向 GOG 版本）；字节匹配构建还需文档指定的 Turbo C++ 1.01 与 TASM 2.0 输入。仅编译原生移植本身不需要游戏数据。",
    "MIT 许可涵盖项目自有工具、文档及新增注释／结构；NOTICE 明确不授予原游戏及派生游戏代码的权利。可选 MT-32 播放需要另行取得的 ROM。",
    "录制会话与例程测试属于上游的有界证据。完整测试需要公开仓库未提供的授权输入。"
