Software RSP-audio-ucode mixer (macro-swap aXxx -> Impl functions, PD-port
pattern) makes libaudio output audible on PC. Alongside it, two pointer-width
bugs surfaced by exercising the audio path for the first time:
- D198: alAdpcmPull/_decodeChunk used K0_TO_PHYS (N64 kseg0 mask) on 64-bit
heap pointers; switched to osVirtualToPhysical like every sibling call site.
- D201: bnkf.c bank/inst/sound/wavetable relocation offsets were s32,
truncating the real 64-bit base pointer for ~50% of allocations; widened
to uintptr_t.
- D200 (already committed-pending from a prior session): reverb's ALDelay
u32 negative indices zero-extended into +4GB offsets on 64-bit; (s32)/(s64)
casts match PD ground truth.
- D199: documents the mixer's aSetBuffer persistent-DMEM-context design,
reconstructed from call-site pairs (no RSP disassembly to check against)
since there's no N64 audio ucode source to reference.
- D195/D197 (playtest reports referenced by an earlier HANDOFF note but never
written into findings.md): backfilled as OPEN with next steps.
Verified: ./build-pc.sh ntsc-final links clean; -level_09 runs 600+ frames
crash-free with music + SFX audible.
- README: attract-mode stills + demo GIF as the hero row, status/warning
callouts, metrics table, "Contents" index, doc-index table; simplified
the two-agent workflow diagram (LR -> TD, fewer edges) for GitHub web
- Table-of-contents indexes added to internals.md, porting-notes.md,
agentic-development.md, AUDIO-PLAN.md
- CI: add Windows/MSYS2 build job, minimal token (contents: read),
persist-credentials: false, concurrency group; run on main + master.
validate job regenerates the US ROM-asset symbol file only and configures
ntsc-final (PAL/JP need a region ROM; no ROM is used in CI)
- .github: SECURITY.md, issue forms + chooser config, PR template,
labels.yml, dependabot (Actions, monthly)
- Do not track the proprietary SGI IRIX IDO toolchain or SGIImageViewer.exe;
document in SetupGuide.md / building.md how to obtain IDO for N64 ROM
builds (the PC port does not need it)
- Stop tracking two committed *.pyc files; drop stale screenshots and a
redundant .gitignore line; misc doc cross-reference fixes
Claude-Session: https://claude.ai/code/session_01GULf6knbsqfsnW39tMr9WT
- README, LICENSE (MIT for the port layer), NOTICE, CONTRIBUTING.
- Restructure docs: internals.md, porting-notes.md, dev-process.md +
dev/agentic-development.md (the research write-up), dev/ (raw record).
- Replace decomp status-badge CI with a PC-port validate workflow.
- Remove session/agent scaffolding and stale planning docs from the tree.
- Add .gitattributes (normalize line endings to LF); add screenshots.
The pre-2026-08 history is the GoldenEye 007 decompilation by Larry Ficken
(KholdFuzion) and contributors, preserved unchanged. The PC-port work from
2026-08-17 on is mine.
