  "description_en": "Decompiles the PS2 executable and 40 overlays of Silent Hill 3 (NTSC-U v1.02) into C for Metrowerks CodeWarrior, and works alongside on the Silent Hill 2 engine, whose debug symbols from a 2001 prototype supply original names for shared code. Builds link with generated assembly for unmatched functions and are checked by SHA-256 against committed hashes. The README calls the project early-stage; decomp.dev reports about 9% of Silent Hill 3 functions and 58% of Silent Hill 2 functions matched at the pinned commit.",

    "Supply the Silent Hill 3 SLUS_206.22 executable and B0.MFA archive; the optional Silent Hill 2 build needs prototype SLUS_202.28 and its overlays.",
    "Hosts are x86-64 Linux, Apple Silicon macOS or Windows through WSL, with Python 3, wget and build tools. make downloads CodeWarrior PS2 3.0.3 for Silent Hill 3 or 2.4 for Silent Hill 2, wibo, PS2 binutils v0.10 and objdiff; it uses the mwccgap submodule.",
    "diff.sh compares the rebuilt executable and overlays with SHA-256 entries; outside CI a mismatch does not fail make. CI uses a private container image.",
    "Project code is MIT; the games and assets retain separate rights. Fifteen files carry Sony confidential notices, and the vsm trees contain disassembled VU microcode. The project prohibits LLM contributions from 2026-09-26."
