- per-file -O0 mechanism: split text c-subseg into boot@-O0 (src/boot.c) + 800@-O2 via splat resegmentation + Makefile target-specific CC1FLAGS; the boot/main/ game-mode-dispatch module (0x80010000-0x800123F0) is -O0, not the pinned -O2 (per-module compiler mixing, SETUP §5.5). Regression-gated byte-identical. - 4 byte-matches (38->42 real, make check BYTE-IDENTICAL throughout): GameModeDispatch (-O0 register-ptr far member), DebugMenuHandler (-O0 reserved-slot local), CdQueueBusy (-O2 if/else order + branch polarity), CdReadRequest (-O2 early-return fall-through) - PsyQ infra: include/psyq/libcd.h (CdlLOC/CdlFILE from the .gdt) + 4 named symbols (CdSearchFile/CdPosToInt/CdIntToPos/VSync) in symbols.us.txt; func_* stubs renamed - loader cluster non-jtbl COMPLETE (6 matched + 2 drafted): NON_MATCHING drafts of LoaderInitFileTable + ResourceLoadStateMachine (logically faithful, residuals in-source) - tooling: progress.py/difficulty.py fixed for the multi-file split (glob src/*.c, all asm dirs, skip forward-decls); deterministic; 42 real / 4 NM - flywheel: matching-cookbook §6 (-O0 detection + idioms), §7 (PsyQ types/symbols), T4 - build byte-identical 143dbb89f34491258bbc27810d0a12ec8b43a8dd from a full clean cycle
BFM-decomp
A matching decompilation of Brave Fencer Musashi (PlayStation, SLUS-00726, USA 1998) — the first public decompilation effort for this game.
What "matching" means
The goal is C source code that, compiled with the original-era toolchain (PsyQ 4.x / GCC 2.7.2-family + ASPSX via maspsx), produces a byte-for-byte identical SLUS_007.26 and, eventually, byte-identical overlay binaries. SHA1 checksums are the ground truth; "functionally equivalent" does not count.
No ROM content
This repository contains no game assets, no disassembly output, and no ROM-derived data — only source code, build configuration, symbol names/addresses, hashes, and documentation. To build or contribute you must provide your own dump of the game disc (4-track BIN/CUE, redump layout). See .gitignore for the firewall.
Project status
Early foundation. Current phase and progress live in phase-ends/ (newest PhaseEnd_*.md = current state). Project methodology, rules, and the full roadmap are in PROJECT_CONTEXT.md. Environment setup is in docs/SETUP.md.
This project is developed primarily by Claude Code driving Ghidra through an MCP server; see CLAUDE.md.
