- 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

# RULE R9: after a Ghidra save-shutdown, verify a recent edit actually persisted to disk.
|
|
# Read-only re-opens the SAVED project and checks the function/symbol name at <addr>.
|
|
# Run AFTER tools/ghidra_mcp_stop.sh (the server must be stopped — a read-only open needs
|
|
# the .rep lock free). Exit 0 = PASS (persisted), non-zero = FAIL / not verified.
|

#
|

# Example (after a phase's last edit was renaming 0x80018730 to LzssDecodeSector):
|
|
# tools/ghidra_mcp_stop.sh && tools/ghidra_mcp_verify.sh 0x80018730 LzssDecodeSector
