- RE'd the full file-loader/overlay subsystem in Ghidra via MCP: CdReadRequest -> CdReadStateMachine (hand-rolled CdControl SeekL/ReadN reader, NOT PsyQ CdRead); LIST.CD RAM cache cdFileLocTable + ResourceGetCdLoc/resourceIdMap lookup; LZSS staging buffer 0x80079A70; loadDestPtrTable; ~50 symbols named (T1-T5,T8) - T6b MILESTONE: resident blob @0x800CEDF8 + location overlay @0x80128158 proven byte-identical (sha1-equal contiguous prefixes) vs live PCSX-Redux RAM; blobs imported into Ghidra (ImportOverlay.java); overlay-map table -> memory-map.md §4.3 - PCSX-Redux runtime oracle: Windows-native build, WSL reads RAM via the web API at 172.17.208.1:8081; ledger #4 resolved - live-verified player/time state: gold(/10) HP BP day hour tiredness boss-HP; save-header template (Q#5) + debug-menu dispatch (Q#9: DEBUG.BIN path is dead) - overlay map: 13 area-states across SC01/02/03, 2 duplicate pairs, location x chapter keying, free-roam vs menu-hub granularity - resolves Open Q#1/#3/#4/#5/#6/#8/#9/#12; corrects SLUS-90029 (FF8 demo, not BFM) - 2 US prototypes acquired + CRC-verified (Aug-31 1369DE07, Sep-8 5C24728E) - rules R9 (verify persistence), R10 (>=3-datapoint live verification), R11 (runtime oracle Windows-native, bridged to WSL) - bumps project version 1.2.0 -> 1.3.0
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.
