A census of every NVN2 program in the RomFS shader packages found 31 that failed in the SM86 lowering, none met in play yet. Each form was checked with nvdisasm. MUFU.F16 (the upscaler's colour decode: a half lane widened, the F32 function, rounded back to a half) in 11 upscaler programs. ATOMS.POPC.INC with the X16 index stride, the luminance histograms' three counters per 16-byte bin, in 8 programs. LDG and STG .STRONG.GPU, read as plain accesses, in 2. TLD.LZ.MS, a 2x MSAA resolve that reads samples 0 and 1, in 3. ATOMG.CAS for the foliage programs' slot claims in 4, through Maxwell ATOM.CAS, which the translator only logged as not implemented: patch 0037 emits a global compare-and-swap for it. SUATOM.D on a 1D image, the post-effect append counters, in 2. ISBERD.O, a task program reading back its own payload, in 1. HighestGpr also counts the registers these forms read beyond the base fields.
All 31 now pass spirv-val, and the other 42,146 programs give SPIR-V byte-identical to the previous translator. tensor_lowering_check passes 29 of 29, with four new MUFU.F16 cases checked against a model of the lowering (the warp emulator gains MUFU); a wrong half select fails all four.

Comments say what the code does and why, docs/maxwell.md keeps the Maxwell facts, and fetch_refs.sh clones only the checkout the build reads. Code is unchanged.

The texture pool descriptors are now a ring of sets, one per submission, brought up to date from a change log, and the first submission of each frame waits for its GPU work before the game goes on: the GPU ran late and part of a frame read data of the next one, and distant characters drew NaN that bloom spread over the frame. The window acquire also waits for the image's previous frame. Function locals start at zero unless DLAA is on, which removes the per-warp light tiles on the Great Fairy Fountain floor and Link's dark, speckled look. Texture slots follow only live entries of their own target, so the volumetric fog gets its 3D volume. The pool refresh walks only the slots that changed.
The translator implements PRMT (patch 0021), which it only logged before; the button prompts render again. HFMA2.RELU no longer depends on it, HMMA.F16 rounds once and HMMA.F32 is lowered, checked against GPU vectors with a new Maxwell warp emulator.
The frame dump gains a re-arming white-frame trigger, a trigger on a depth target's first pass, NaN pixels in magenta, image handles and view targets, and depth copies of sampled depth textures.
