    "README reports the game code fully decompiled and the CRI middleware partly decompiled, with most file-system and sound functions the game uses matching; cri-progress.md checks off 497 of the 503 CRI functions it lists. At the reviewed commit, two game functions (sea_write and mlt_obj_trans_rgb_ext) and 39 of 52 CRI C files still include assembly in the PS2 build, and PS2 SDK and GCC library code is out of scope. The output is the PS2 executable, not a PC port.",
    "Building needs THIRD_U.BIN from the user’s own copy of the game; the split configuration records its SHA-1 as cf58495054c31ad852175c66e9ca04d5094f000e, and make split derives the assembly and linker script from it. The decompiling guide also relies on the executable’s DWARF debug data, dumped with decomp-toolkit, for signatures and local variables. A separate split_cps3 target for the CPS3 arcade version needs a user-supplied arcade ROM set and has only a code-segment configuration.",
    "The build guide covers Linux (Debian packages with i386 support, MIPS binutils, and a Python venv with splat64 0.29.0 and spimdisasm 1.35.0) and macOS through the provided Dockerfile. make setup_tools downloads Metrowerks mwccps2 3.0b38 and EE GCC 2.96 from decomp.me’s compiler releases plus the wibo loader for Windows tools; m2c, asm-differ, mwccgap and saturn-splitter are git submodules.",
    "A successful build ends with compare_bytes.py checking the rebuilt executable against the original from offset 0x80 to 0x478A00 and printing “Files match ✅”. That check tolerates 163 listed words in about 20 game and CRI functions, attributed to register and operand swaps, assert line numbers, string encoding, a misplaced nop and a call misalignment, so equivalence is near-byte-level by the project’s own check rather than a whole-file hash. The latest commit removed the GitHub Actions workflows.",
    "LICENSE is AGPL-3.0 for the project’s code. The original executable and game content keep their own rights; include/cri carries headers marked “CRI Middleware SDK” and “Copyright (c) … CRI-MW”, and the vendored zlib keeps its own license."

    "README 报告游戏代码已全部反编译，CRI 中间件部分反编译，游戏所用的大部分文件系统和声音函数已一致；cri-progress.md 所列 503 个 CRI 函数中已勾选 497 个。在所审提交中，PS2 构建仍有两个游戏函数（sea_write 和 mlt_obj_trans_rgb_ext）及 52 个 CRI C 文件中的 39 个包含汇编；PS2 SDK 和 GCC 库代码不在范围内。产物是 PS2 可执行文件，不是 PC 移植。",
    "构建需要使用者从自己的游戏副本中取得 THIRD_U.BIN；拆分配置记录其 SHA-1 为 cf58495054c31ad852175c66e9ca04d5094f000e，make split 据此生成汇编和链接脚本。反编译指南还借助该可执行文件中的 DWARF 调试数据（用 decomp-toolkit 导出）获取函数签名和局部变量。另有面向 CPS3 街机版的 split_cps3 目标，需要使用者自备街机 ROM，目前只有代码段配置。",
    "构建指南涵盖 Linux（需启用 i386 支持的 Debian 软件包、MIPS binutils，以及装有 splat64 0.29.0 和 spimdisasm 1.35.0 的 Python 虚拟环境），macOS 则使用所提供的 Dockerfile。make setup_tools 从 decomp.me 的编译器发布中下载 Metrowerks mwccps2 3.0b38 和 EE GCC 2.96，并下载用于运行 Windows 工具的 wibo；m2c、asm-differ、mwccgap 和 saturn-splitter 是 git 子模块。",
    "构建成功后，compare_bytes.py 将重建的可执行文件与原文件在偏移 0x80 至 0x478A00 范围内比对，并输出 “Files match ✅”。该检查容许约 20 个游戏与 CRI 函数中列明的 163 个字存在差异，原因注明为寄存器与操作数互换、断言行号、字符串编码、一处错位的 nop 和一处调用错位，因此按项目自身的检查，一致性接近字节级，而非整个文件的哈希一致。最新提交移除了 GitHub Actions 工作流。",
    "LICENSE 为 AGPL-3.0，适用于项目代码。原可执行文件和游戏内容仍有各自权利约束；include/cri 中有标注 “CRI Middleware SDK” 及 “Copyright (c) … CRI-MW” 的头文件，内置的 zlib 也保留其自身许可证。"
