  "description_en": "Virtua Tennis decomp reconstructs the Dreamcast game's executable from a user-provided disc, first establishing a byte-matching assembly baseline and then substituting C for game functions. Its tools generate function tests and asset maps for models, textures, text and audio. The author reports C has been written for every function with a C form, with behavioral equivalence as the completion criterion.",
  "description_zh": "Virtua Tennis decomp 从用户提供的 Dreamcast 光盘重建游戏可执行文件，先建立逐字节匹配的汇编基线，再逐步以 C 代码替换游戏函数。工具还生成函数测试，以及模型、纹理、文本和音频的资源映射。作者报告所有可用 C 表达的函数均已有 C 代码，并以行为等价作为完成标准。",
