    "README describes a work-in-progress decompilation of the US PlayStation MediEvil 1, with MediEvil 2 left for later. The Makefile targets SCUS_942.27, MEDIEVIL.EXE and 26 overlay binaries. In the reviewed tree most functions are still included as split assembly through INCLUDE_ASM rather than written in C, README's progress section is a placeholder, and the pinned commit dates from 2026-02-23.",
    "Requires files from the user's own US MediEvil disc in disk/; the splat configuration expects SCUS_942.27 with a fixed SHA-1, and make extract splits the executables and overlays from those files. The repository supplies no game files.",
    "The build expects a Linux-style host: GNU make, mipsel-linux-gnu binutils, Python 3 with the listed packages such as spimdisasm and rabbitizer, and the splat, m2c, maspsx and asm-differ submodules. C files go through a bundled PlayStation GCC 2.8.1 cc1 binary and maspsx. README points contributors to wiki pages for setup, the rebase workflow and the decompilation process.",
    "make all builds every binary and runs sha1sum against config/medievil.check.sha; CI runs extraction and that check using disc files from an access-restricted repository. A passing check shows that the assembled outputs match those checksums.",
    "The repository declares MIT; original game content, the bundled compiler binaries and the PSY-Q headers and data in the tree retain their own terms. The project is separate from the MediEvil Recomp static recompilation."

    "README 将其描述为针对美版 PlayStation《MediEvil》初代、仍在进行中的反编译项目，MediEvil 2 留待以后。Makefile 的目标为 SCUS_942.27、MEDIEVIL.EXE 及 26 个覆盖模块二进制文件。在所审版本中，大部分函数仍通过 INCLUDE_ASM 以拆分出的汇编形式纳入，而非以 C 编写；README 的进度部分仅为占位，固定的提交日期为 2026-02-23。",
    "需将使用者自有美版 MediEvil 光盘中的文件放入 disk/；splat 配置要求 SCUS_942.27 具有固定的 SHA-1，make extract 从这些文件拆分出各可执行文件和覆盖模块。仓库不提供任何游戏文件。",
    "构建需类 Linux 宿主环境：GNU make、mipsel-linux-gnu binutils、安装所列软件包（如 spimdisasm、rabbitizer）的 Python 3，以及 splat、m2c、maspsx 和 asm-differ 子模块。C 文件经由仓库内置的 PlayStation GCC 2.8.1 cc1 二进制文件和 maspsx 处理。README 让贡献者参阅 wiki 页面，了解环境配置、变基工作流和反编译流程。",
    "make all 构建全部二进制文件，并依据 config/medievil.check.sha 运行 sha1sum；CI 使用访问受限仓库中的光盘文件执行拆分和该检查。检查通过说明汇编产物与这些校验值一致。",
