The first real PsyQ library is sourced from real SDK objects in the byte-identical
build, replacing the libcd-region asm stubs. Tasks 2'.1/2'.2/2'.3 — the whole
PsyQ-library-into-build mechanism, proven on the simplest library (libcd).
- psyq_link.py: per-object byte-link engine — recovers externals from the EXE's
resolved relocations (R_MIPS_26 / HI16+LO16); weakens psyq-obj-parser's
mislabelled common-style .bss globals so a strong --defsym wins
- psyq_link_lib.py: whole-library verify — 18/18 libcd objects byte-identical
- psyq_link_region.py: region link via NOLOAD data placement (no carving) +
weaken-all-.bss; gap-aware per-object placement
- psyq_integrate.py: build wiring — splat resegment swap + per-object .text at
vram + NOLOAD data; external resolution (func_<addr> aliases, symbols.us.txt
jump-table names, recovered St*/CD_* globals, all weakened .bss commons);
idempotent; conditional on tools/psyq/ (fresh clone builds via stubs)
- split_src_region.py: H5-safe src/*.c split at vram boundaries (preserves
matched C + NON_MATCHING blocks)
- splat.us.exe.yaml: 5-way text split [pre][libcd1][gap][libcd2][post]
- src/800.c trimmed to <0x80043088; src/{800b,gap,libcd1,libcd2}.c splat stubs
- Makefile: libcd integration in the $(OUT) recipe (conditional + idempotent)
- cookbook §9.1/9.2/9.3 (the reusable mechanism for libgs/Gen2); CURRENT_PHASE
session-D log; ≥3-session green bar A/B/C/+D
- make clean && extract && build && check -> 143dbb89... BYTE-IDENTICAL
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.
