- Pipeline archive: the Metal 4 serializer leaves a com.apple.gpuarchiver/gpuarchiver-* folder per flush (456 folders, 2.5 GB on this Mac). The first capture after a flush takes the one folder it made, the flush removes it (and the one a recapture-only flush makes), exit removes an unflushed one; iOS clears earlier runs' folders at start (MacNativeGames 1eff989, 110e6c6). - tex_desc: levels past what the size holds, arrays of no or more than 2048 layers, sample counts the GPU lacks no longer abort the process; copies and ReadTexels at a missing level are skipped (f864eb0). - nvn_hm_get compares 8-byte keys as one word: 5.9 -> 1.5 ns a lookup (7431eb7). - frame-rate.md: segment size cannot change BotW's 60 fps frame on the Mac (fence wait 0.02 ms).
Subsystem references
How the host meets each part of a Switch game, and every failure met so far, one entry per mechanism: symptom, cause, fix (file and function), the games it was found on (linked to their notes in dm/games/<id>/README.md). Start from the symptom index when you have a log line or a visible result; the workflows that lead here are in docs/agents.
| File | Covers |
|---|---|
| packing.md | NSP script, compressed inputs and build artifacts |
| rewriter.md | The NSO rewriter patch_nso.py: jump tables, exclusive windows, patch area reach, cuts and observation gates, functions without unwind entries, stack and system registers, relocations |
| memory.md | Guest layout, heap and application pool, virtual address memory and the alias region (the SDK's node area), engine allocators, mapping SVCs, running out of memory |
| threads.md | Thread creation and cores, address arbitration, yields and spin waits, events |
| services.md | SDK calls and system services: sm connections, names that changed between SDKs, file system and saves, add-on content, input, keyboard and applets, display and operation mode, accounts and network, settings and fonts, C library and time, modules |
| movies.md | The SDK's movie library: decoder lifecycle, output slots, native-texture output, demuxers and codecs, game movie players |
| audio.md | The audio renderer and its command lists by SDK, AudioOut and devices, codecs, timing |
| frame-rate.md | The host's frame step, engine frame limiters, present intervals and display rates, CPU cost |
| nvn-objects.md | NVN object sizes, memory pools, command memory, queues and syncs, CPU-written textures, NVN entry points |
| rendering.md | The replay on Metal: textures, passes and clears, blend / depth / stencil, vertex input, uniforms and ordering, conditional rendering; the Vulkan and OpenGL layers |
| shaders.md | Shader containers by engine, control sections and code, translation, bindings and handles, shaders compiled at run time, pipelines and caches |
| game-state.md | Saves, scripted state, and game behaviour that looks like a host bug but is not |
A new general finding goes into the file and section it belongs to, in the same form, with a line in the symptom index; a fact about one game goes into that game's note.
