  "description_en": "Ports Eidolon, Poo-Brain’s winning PC 64k intro from Revision 2017, from its packed 60,928-byte Windows executable to Rust, with chapters on how the original binary works and a separate size-optimized build. The author reports that coordinated OpenCode and Claude Code agents, using Ghidra through the REA MCP server among other tools, captured a controlled-clock reference of the original and matched all 27,000 frame hashes and the full PCM. Exactness rests on the project’s own GPU-specific captures, and the port embeds the original’s data.",

  "requirements": [
    "The Rust port targets i686-pc-windows-gnu. The documented Linux build uses Rust 1.97, MinGW-w64, Clang, Python, Wine and headless gamescope; the size build also needs NASM. Reference capture and size builds run on Linux, while macOS cannot run the intro.",
    "A new reference capture needs the original scene.org release archive and gm.dls from a Microsoft DirectX redistributable, both checked by SHA-256. The port embeds original tables, curves, shaders and music plus 15 Roland GM/GS samples; the size build reads system gm.dls.",
    "Under a controlled clock, the project reports matching 27,000 frame hashes and the full PCM. Shipped frame hashes fit its RTX 3070 Ti, driver and Wine setup; other GPUs need a local reference capture. Most fault-injection tests need 5.8 GB of unpublished raw reference data; 57 tests run without it. Native Windows playback and frame checks remain untested.",
    "The size build is 44,139 bytes versus the original 60,928 bytes; it did not reach the 32 KiB target. The author reports agent-led work with human goal setting and decisions.",
    "Rust code, tools and documentation are MIT or Apache-2.0. Bundled kkrunchy source is public domain. Original shaders, music, animation data and Roland samples retain their owners’ rights and are outside those licenses."

    "重新捕获参考需要 scene.org 上的原版发布包和 Microsoft DirectX 可再发行组件中的 gm.dls，两者均通过 SHA-256 校验。移植版嵌入原作数据表、曲线、着色器、音乐及 15 个 Roland GM/GS 采样；体积优化版读取系统中的 gm.dls。",
