D73+D74: intro logo fixed (sinf/cosf endianness + texture import/sub-tile wrap)
D73 (root cause of old D72.3): GE's sinf/cosf build their double
constants through the du bit-union with big-endian word pairs {hi,lo};
on LE PC the .d read has the words swapped (rpi.d ~ 2^733), range
reduction overflows, and FTOFIX32 saturates to -32768 for every
sin/cos entry of guMtxF2L — so the Rareware logo's rotation matrix was
garbage and all its triangles projected off-screen. Fix: DVAL() macro
in src/libultra/gu/guint.h (PORT-only; #else branch is the original
expression) re-packing hi/lo into the correct LE double; sinf.c/cosf.c
.d reads replaced. N64 build untouched.
D74 (texture side, three port-layer bugs in fast3d):
- import_texture's fallback condition (rdp.tex_lod && tile >=
first+detail) overwrote valid gDPLoadBlock tmem data with
line*tile.height: letter mip chains 2744B -> 2048B (mips 1-5 dropped),
D_02005FF0 32x32 -> 32x3 (stale tile.height from gsDPSetTileSize).
Now falls back only when the tmem slot was never written.
- TextureCacheKey gains size_bytes so a truncated first import cannot
poison later full imports of the same address.
- VBO UV path now wraps by TILE size for WRAP sub-tiles (N64 semantics);
the logo's 20x3 tile at offset (11.5,29) was sampling row 0 instead
of rows 29-31. Per-vertex pre-wrap; known limits: half-texel edge
bleed, mirror sub-tiles unhandled.
Verified: clean runs reach frame ~2100 then hit the D69 load_bg_file
fault (unchanged — still the milestone blocker); PPM frame ~555 shows
the four gold RARE letters on the dark-blue plate (final pixel-perfect
check vs N64 footage left as a low-priority task). All env-gated probes
from this session (GE_DBGUV/DBGTRI/DBGTALL/DBGMAT/D74IMP/D74DUMP/
GE_DBGLOAD) stripped; previously committed TEMP D63 blocks + GE_D71LOG
remain on the HANDOFF strip list.
Docs: PCPortResearch.md §F D73/D74 entries, §G/§H status updated;
HANDOFF.md rewritten for Session I (D69 primary); AGENTS.md phase line.

- **Compile+link milestone:** all ~235 TUs compile and `ge007.x86_64.exe` links clean (`ninja ge007 -k 0`, 236/236). Findings D7–D17 in `docs/PCPortResearch.md` §11; asset stubs in `port/src/assetstubs.c`, fast3d no-ops in `port/src/gfxstub.c` (delete when real fast3d lands).
|
||||
- **Phase 1 (boot to window):** done — ROM loads/validates/maps at cart base 0x10000000 (`romdata.c`), SDL2 window + GL clear loop (`video.c`), absolute asset symbols from `scripts/gen_romassets.py` → `port/src/romassets_<r>.s` (findings D18–D23).
|
||||
- **Phase 1.5 (boot to first frame):** DONE — boot chain complete AND real frames render (`[NOTE] frame N rendered in … us`). D34–D42 closed the blockers on top of D31–D33: ANIM_DATA lvalues, music seq-table ABI+endianness, music-heap sizing, libaudio bank-tree re-layout, implicit-declaration prototype shim (D38), Globalimagetable rebasing + true segment size (D39), ModelHitEntry pool sizing (D40), cross-thread GL context release (D41), rsp task-settings toggle (D42). ROM dump verified against the No-Intro good dump (byte-identical, header CRCs re-checked — `tools_pc/romverify.c`).
|
||||
- **Phase 2 (rendering):** IN PROGRESS — fast3d integrated + real frames render. **Plan B EXECUTED (D50, committed):** all 512 NTSC model files converted offline by `tools_pc/d43_emit.py` → `data/pcmodels-ntsc-final/pcmodels.bin` + manifest.csv (single concatenated RZ image; regenerate per region with the script — sidecars are gitignored), served through the existing load path via a port-layer table patch (`port/src/pcmodels.c`, romdata cart-extension, one-shot `pcmodelsPatchTable()` + poolRemaining reset hook in `load_object_fill_header`); runtime C fixups for language-bank BE offset tables + font re-layout (D50.3/D50.4); legal-screen UB seed (D50.5); **D50.6 fixed the first model-render crash** — `texCopyGdls` copied only w0 of each 16-byte Gfx slot on PC (the union's trailing `long long` is 8 bytes), leaving stale mempool w1s in the compacted GDLs; byte-proven against PlegalpageZ, fixed with a full-slot copy under #ifdef PORT. Model GDLs now execute to completion (PlegalpageZ sub-DLs). **D51 RESOLVED** (font `pixeldata` fixup wrote the pointer at the wrong offsets — frame-5 `import_texture_i8` crash gone; GE opcode space decoded along the way, G_TEXRECT=0xE4/0xE5 non-F3DEX numbering), **D52 RESOLVED** (`osGetCount` now advances at the N64 RSP counter rate ≈ 46.5525 ticks/µs — fixed the non-deterministic post-frame-2 hang), **D53 RESOLVED** (model RW-data pool addressing: D53.1 `Model.datas` word-stride → `u32 *` under PORT + casts; D53.2 ModelSlot/AnimModelSlot re-laid on top of the PC struct Model — in-use@0x10 / pool@0x20, slot size = sizeof(Model) = 0xE8 — plus PORT-guarded heap-fallback bumps in model.c), **D54 RESOLVED** (cseq ALCMidiHdr BE header: port-layer `romdataFixupCseq` bswap32 of the first 17 u32s, called from music.c after each decompress), **D54b RESOLVED** (synth param slots sized for ALStartParamAlt = 0x28 in synthesizer.c alSynInit under PORT), **D55 RESOLVED** (RLE folder-menu background BE w/h header: bswap32 of the first word at `(u32 *)&unknown2` at cart-map time in romdataInit, guarded). Build GREEN; game boots, plays intro music, renders through logo/gun-barrel, instantiates Brosnan, and executes the gun-barrel hole DL clean to ENDDL. **D56 RESOLVED** (watch Model/RW-pool raw offsets: field-name Model access + static 0xC8-byte pool under PORT in bondview2.c), **D57 RESOLVED** (pointer-grown rwdata records overflowed N64-sized spare pools — Brosnan PC numRecords 153 > 140: capacities grown in initunk_005520.c + dynamic slot+pool fallback in model.c), **D58 RESOLVED** (gun-barrel DL: vertex-pointer K0 idiom rebuilt via `OS_K0_TO_PHYSICAL(…) | 0x80000000` in title.c + DL reserve 0x100→0x200 because `sizeof(Gfx)` is 16 on PC). **D59–D68 RESOLVED (committed):** the "GL DLL" crash was D64's unbounded blood-RLE write (sentinel section-adjacency lost on PC) clobbering the gun-barrel sub-DL; then D60–D62 (DMA target validation, OSMesgQueue layout), D65/D65b (HEADS/BODIES enum signed sentinels under PORT), D66 (romCopyAligned + ramrom replay 64-bit pointer width), D67 (struct image_entry N64 layout), **D68 (Globalimagetable BE→LE fixup** — `port/src/gimgfixup.c` bswaps IMAGESEG Gfx w1 words + sImageTableEntry.index after texReset's romCopy; compiled globalDL shadows synced for explosion.c). The game now renders the **entire ~3.5-minute intro** (logo → gun barrel w/ Brosnan → cast) at ~59 fps. **Current blocker D69:** `load_bg_file` (bg.c:830) faults on first stage load — BG-file headers/records are N64 big-endian segment-0x0F offsets, read LE on PC; the bg `.seg` + `Tbg_*_stanZ` format work is next (decode from bg.c/stan.c → offline sidecar conversion per the D43 pattern or runtime port-layer fixup; PD `preprocess/filebg.c` is approach-reference only — its BG format differs). **D70–D72 (intro-logo pixels):** D70 env-gated PPM frame capture (`GE_PCDUMP` → `./ppm/`, gitignored); **D71 RESOLVED** — C-array texture sources (the four rarewarelogo.c RGBA16 images) byte-swapped on LE PC → pink/green logo; port-layer per-source bswap in `import_texture`; **D72 RESOLVED** the UV path (GE always uses authored `tc[]` UVs — no G_TT_BASE/CLAMP anywhere; `lookat_enabled` defaults false since N64 boots with RSP mem zeroed) but **D72.3 OPEN**: all logo triangles project off-screen and a flat dark-blue checkerboard triangle rasterizes instead (identity pending via `GE_DBGUV`/`GE_DBGTALL` traces); D69 remains the milestone blocker. Committed through D72. Recurring sub-task: ABI/layout fixes per the D32 procedure (§H) as more asset types are first touched (PD's `preprocess/` module already solves most of them; prefer the offline pattern for format work — D48; full-struct Gfx copies on PC — D50.6; audit struct type-puns after pointer-width changes — D53.2; raw byte offsets into pointer-containing structs shift on PC — D56; N64-sized reservations must be re-checked against 16-byte Gfx/Vtx widths — D58).

|

`docs/PCPortResearch.md` (§F/D59–D74 findings, §G status, §H procedure); this

is the summary + the immediate tasks._
|
||||
|
||||
## Your job
|
||||
|
||||
- **Session H:** two live threads, both verified reproducible:
|
||||
1. **D72.3 (intro logo pixels):** after D71 (logo byte order) + D72 (tc[]
|
||||
UVs), the Rareware logo still doesn't appear — all its triangles project
|
||||
off-screen, and a flat dark-blue checkerboard triangle (broken
|
||||
rasterization of something else) fills the lower screen instead. Tools
|
||||
are in place: `GE_PCDUMP` frame capture + `GE_DBGUV`/`GE_DBGTALL`
|
||||
traces in gfx_pc.cpp. Find which triangle draws the checkerboard, then
|
||||
check MP matrix + viewport at logo time (title.c
|
||||
load_display_rare_logo).
|
||||
2. **D69 (milestone):** make the first stage (BUNKER1) load and render —
|
||||
BG-file data is N64 big-endian; reverse-engineer GE's bg `.seg` +
|
||||
`Tbg_*_stanZ` formats from the decompiled consumers, then convert/fix
|
||||
for PC.
|
||||
Work agentically: decode → implement → build (~5 s) → verify → commit at
|
||||
each sub-milestone (document findings as D6x/D7x in §F).
|
||||
- **Session I — D69 (the milestone blocker):** make the first stage (BUNKER1)
|
||||
load and render. BG-file data is N64 big-endian; reverse-engineer GE's bg
|
||||
`.seg` + `Tbg_*_stanZ` formats from the decompiled consumers, then convert
|
||||
or fix them for PC. This is the only thing standing between the intro and
|
||||
gameplay (verified: clean runs reach frame ~2100 in ≈2 min wall-clock, then
|
||||
fault deterministically in `load_bg_file`, bg.c:830).
|
||||
- **Secondary (low priority):** final pixel check of the intro logo. D73 +
|
||||
D74 fixed it at the data level and PPM frames ~550–560 show four gold
|
||||
letters on the dark-blue plate; compare against N64 reference footage if
|
||||
time allows (reference screenshots are at repo root: `Graphics Screenshot
|
||||
2026-08-24 121659.jpg`, `gun barrel.png`).
|
||||
- Work agentically: decode → implement → build (~5 s) → verify → commit at
|
||||
each sub-milestone (document findings as D7x in §F).
|
||||
|
||||
## Current state (verified this session)
|
||||
|
||||
- **Build GREEN.** `export PATH="/c/msys64/mingw64/bin:$PATH" && ./build-pc.sh ntsc-final`.
|
||||
- **D59–D68 all resolved** (details in PCPortResearch.md §F). Highlights:
|
||||
- **D59/D64** — the old "GL DLL" crash was an unbounded blood-RLE write
|
||||
(sentinel `die_blood_image_end` lost its N64 section adjacency on PC)
|
||||
clobbering the gun-barrel sub-DL. Sentinel now defined as one-past-the-
|
||||
end of the array under PORT.
|
||||
- **D65/D65b** — `enum HEADS`/`BODIES` sentinels: N64 semantics were signed
|
||||
(`HEAD_FIXED == -1`); PC GCC 16 picks unsigned underlying types, deleting
|
||||
the guard branches. Negative literals under PORT restore the bit pattern
|
||||
with signed semantics.
|
||||
- **D66** — `romCopyAligned` + ramrom replay did s32 pointer math; targets
|
||||
in `.bss` > 4 GiB truncated to wild addresses. 64-bit version under PORT,
|
||||
returns `void *`.
|
||||
- **D67** — `struct image_entry` re-laid (all-u32 bitfields, `dataoffset:24`
|
||||
first) so texLoad's raw word read + chrprop.c's 8-byte stride agree;
|
||||
sizeof == 8 on both targets.
|
||||
- **D68** — Globalimagetable BE→LE fixup (`port/src/gimgfixup.c`): bswap the
|
||||
IMAGESEG-marked Gfx w1 words (17 DLs) + `sImageTableEntry.index` (32
|
||||
tables, counts from D39 layout) after texReset's romCopy; marker scan in
|
||||
`texLoadFromDisplayList` moved to bytes 6..7 under PORT; compiled
|
||||
globalDL shadows synced after texLoad (`gimgSyncCompiledGlobalDLs`).
|
||||
- **D70–D72 (intro logo pixels, latest session):** D70 env-gated PPM frame
|
||||
capture (`GE_PCDUMP` → `./ppm/`, gitignored); D71 RESOLVED — C-array
|
||||
texture sources (the four rarewarelogo.c RGBA16 images) were byte-swapped
|
||||
on LE PC → pink/green logo; port-layer per-source bswap normalizes them.
|
||||
D72 RESOLVED the UV path (GE always uses authored tc[] UVs; lookat defaults
|
||||
off) but **D72.3 OPEN**: all logo triangles project off-screen and a flat
|
||||
dark-blue checkerboard triangle rasterizes instead — see Your job #1.
|
||||
- **Runtime:** boots → intro music → full intro (logo, gun barrel w/ Brosnan,
|
||||
cast screen) at ~59 fps → **crash in `load_bg_file` (bg.c:830)** on first
|
||||
stage load. EXCEPTION 0xc0000005, FAULT ADDR ≈ header buffer + 0x500000F.
|
||||
- **Committed through D72** (see git log). TEMP diagnostics from the
|
||||
D51–D72 sessions are still in the tree — strip list in Task 3.
|
||||
- **D59–D68 resolved** (details in PCPortResearch.md §F): blood-RLE sentinel,
|
||||
HEADS/BODIES signed sentinels, romCopyAligned/ramrom 64-bit, image_entry
|
||||
layout, Globalimagetable BE→LE fixup (`port/src/gimgfixup.c`), etc.
|
||||
- **D70–D74 (intro logo) resolved:**
|
||||
- D70: `GE_PCDUMP` PPM frame capture (kept — permanent dev tooling).
|
||||
- D71: C-array texture sources (rarewarelogo.c RGBA16 images) bswapped on
|
||||
LE PC → port-layer per-source normalization in `import_texture`.
|
||||
- D72: GE always uses authored `tc[]` UVs; `lookat_enabled` defaults false.
|
||||
- **D73 (root cause of the old D72.3):** sinf/cosf `du` double constants
|
||||
are big-endian word pairs → garbage on LE PC → guMtxF2L emitted −32768
|
||||
for every sin/cos entry → logo triangles projected off-screen. Fixed with
|
||||
the `DVAL()` macro in `src/libultra/gu/guint.h` (PORT-only; N64 build
|
||||
untouched). All scenes using guRotate/guLookAt-derived matrices were
|
||||
affected, not just the logo.
|
||||
- **D74:** texture import fallback no longer truncates valid gDPLoadBlock
|
||||
data (was dropping letter mip chains and reducing D_02005FF0 to 32×3);
|
||||
`TextureCacheKey` gained `size_bytes`; VBO path now wraps UVs by tile
|
||||
size for WRAP sub-tiles (N64 semantics; the logo's 20×3 sub-tile at
|
||||
offset (11.5, 29) was sampling row 0 instead of rows 29–31).
|
||||
- **Runtime:** boots → intro music → full intro (Rareware logo with gold
|
||||
letters, gun barrel w/ Brosnan, cast screen) → **crash in `load_bg_file`
|
||||
(bg.c:830)** on first stage load. EXCEPTION 0xc0000005; the crash log at
|
||||
repo root (`ge007.crash.log`, gitignored) is from this exact fault:
|
||||
PC=0x14000627c, FAULT ADDR = Rax+0x28 (reading `pPointTableBin` through the
|
||||
mis-rebased room-fileposition pointer).
|
||||
- **Committed through D74.** This session's TEMP probes are all stripped;
|
||||
previously committed TEMP diagnostics remain — strip list in Task 3.

matrix-format or UV problem: guMtxF2L's sinf/cosf inputs were garbage on PC.
|

|
||||
**D73 (RESOLVED — root cause of D72.3):** GE's `sinf`/`cosf`
|
||||
(src/libultra/gu/sinf.c, cosf.c) build their double constants through the
|
||||
`du` bit-union (`{ struct { u32 hi; u32 lo; } word; double d; }`) with
|
||||
big-endian word pairs `{hi, lo}` (rpi, pihi, and the P[] polynomial tables).
|
||||
On an LE PC the `.d` read has the two words swapped: `rpi.d` ≈ 2^733,
|
||||
`pihi.d` ≈ 2^257. Range reduction then overflows: `dn = dx*rpi.d` huge →
|
||||
ROUND(dn) saturates in cvttsd2si (n = −2^31) → `dx = dx − dn*pihi.d` ≈ 2^288
|
||||
→ xsq ≈ 2^576 → the result overflows float → sinf/cosf return ±inf/NaN.
|
||||
FTOFIX32's `(int)(±inf·65536)` is another cvttss2si saturation →
|
||||
0x80000000 (−32768). Every sin/cos-derived entry of guMtxF2L became −32768,
|
||||
so the Rareware logo's guRotate matrix was garbage and all its triangles
|
||||
projected off-screen (the D72.3 symptom; the "checkerboard" was a separate
|
||||
large triangle rasterizing over the empty logo region). The logo scene is the
|
||||
first visually verifiable consumer of guMtxF2L sin/cos output in the intro;
|
||||
other scenes that build matrices via guRotate/guLookAt are affected by the
|
||||
same bug and were fixed by this change. Fix (narrow ABI exception — constant

interpretation only, algorithm verbatim): `duD()` static-inline + `DVAL(x)`
|

macro in src/libultra/gu/guint.h under #ifdef PORT re-pack hi/lo into the
|

correct LE double; the 5 `.d` reads in sinf.c and 4 in cosf.c now use
|
||||
`DVAL(...)`. The N64 build is untouched (#else branch = original expression).

Only sinf.c/cosf.c use `du` (grep-verified); `fu` (single u32) constants are

endian-safe. Verified numerically: P decodes to the expected perspective

matrix, Rot(−40°Y) gives clean cos=0.766/sin=−0.643, and logo vertices clip

to small finite on-screen NDC values. (tools_pc/mtxtest.c is a standalone
|
||||
scratch harness for the matrix-convention question that was ruled out along
|
||||
the way — GE stores all matrices transposed; row-vector ≡ column pipeline.)
|
||||
|
||||
**D74 (RESOLVED — final pixel check pending):** with D73 in, logo geometry
|
||||
was correct but the texture side was still wrong: a dim red-brown blob plus
|
||||
a flat vertical bar at the right edge, one letter visible at a time. Three
|
||||
port-layer bugs, all in port/fast3d/gfx_pc.cpp (with gfx_pc.h):
|
||||
- **Import fallback truncation.** `import_texture`'s old condition
|
||||
`(rdp.tex_lod && tile >= rdp.first_tile_index + rdp.tex_detail) ||
|
||||
!loaded_texture.addr` overwrote valid gDPLoadBlock tmem data with
|
||||
`line_size_bytes * tile.height`. For the logo: letter mip chains 2744 B →
|
||||
2048 B (mips 1–5 dropped), and D_02005FF0's 32×32 → 192 B (32×3, stale
|
||||
tile.height=3 left by `gsDPSetTileSize(0, 46, 116, 124, 124)` in DL
|
||||
D_02004758). Fix: fall back only when `!loaded_texture.addr` (N64 TMem is
|
||||
persistent — a populated slot is the faithful source).
|
||||
- **Cache poisoning.** TextureCacheKey lacked the upload size, so the first
|
||||
(truncated) import of an address poisoned every later import. Added
|
||||
`size_bytes` to the key (gfx_pc.h + both key initializers + the bucket-only
|
||||
aggregate in gfx_texture_cache_delete).
|
||||
- **Sub-tile UV wrap period.** N64 wraps UVs by the TILE size when a render
|
||||
tile is a sub-region of the image; the port wrapped at the full uploaded
|
||||
image size (GL_REPEAT). D_02004758's 20×3 tile at offset (11.5, 29)
|
||||
therefore sampled row 0 instead of rows 29–31 — the flat bar's color
|
||||
matched texel [0,4] of D_02005FF0 exactly. Fix: per-vertex pre-wrap in the
|
||||
VBO path — for a WRAP sub-tile (`tex_width2 < tex_width`, where
|
||||
`tex_width2 = (lrs−uls+4)/4` is the tile window in texels),
|
||||
`u = fmodf(u, tw); if (u<0) u += tw; u += uls/4.0f` (same for v). Known
|
||||
limitations: half-texel edge bleed at the sub-tile window edges (GL
|
||||
bilinear neighbors may sample just outside [O, O+W)); mirror sub-tiles are
|
||||
not handled (the logo doesn't use them; audit if another scene regresses).
|
||||
Verified: runtime import sizes correct (D_02005FF0 = 2048 B, imgRAre =
|
||||
2744 B); PPM frame ~555 shows the four-letter RARE band with gold/warm
|
||||
colors and per-letter segmentation; clean `GE_PCDUMP` runs are stable past
|
||||
1156 frames. Final pixel-perfect confirmation against N64 reference footage
|
||||
is still open (see HANDOFF Task 1). All env-gated probes added for D72.3/D74
