- LzssDecodeSector (0x80018730): asm-differ score 0, make check BYTE-IDENTICAL; NON_MATCHING guard dropped (C is the default build) - closed the session-E ~4 regalloc/scheduling residuals via the §3a research tier (ground-truthed vs pinned gcc-2.7.2 reorg.c/jump.c/local-alloc.c) + a floor-free .text object metric (the permuter could not measure it: rodata/jtbl score floor) - 5 LOAD-BEARING constructs documented in src/800.c + cookbook §10: (A) decoupled nh high-byte var + (code&0xFF)|(nh<<8) operand order [combine_regs] (B) result set in save predecessors [reorg fill_simple_delay_slots] (B/state-2) explicit register $2 local + early read-only input-asm pin [sched] (B3) no switch default -> state>=5 reuses the sltiu result (§5a) zero-byte cross-jump barrier (retained) - cookbook §10 added (reusable regalloc/schedule-tail idioms + the .text metric), §5a cross-linked; CURRENT_PHASE task + green-log updated (Gen1-exit LZSS gate MET)
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.

Private repository for now. AGPL-3.0 is planned at public release, modeled on sotn-decomp. tools/brave-CUE/ is CUE's BRAVE extractor (GPL, source included) and retains its own license.
