One Rule-2 #ifdef PORT draw hook in constructor_menu05_fileselect (user
sign-off 2026-09-27). The label's hit test and open request live in
optionsoverlay.c; the open is applied on the input thread. While the
overlay is open on file select, g_MenuTimer is held at 0 so the screen no
longer drops to the legal screen after 30 s.
The crop tested loaded_texture.line_size_bytes, which is the whole
LoadBlock (1400 B), so the water still uploaded 32x43 while UVs were
normalised to 32 rows; the mip rows showed as coloured dashes. Test the
tile line size instead. User-verified on Frigate; golden 3/3.
The PC wallet model (0x1664C B, 0x17000 reservation) loads at the start of
ptr_logo_and_walletbond_DL, but the file-select scratch DL and the
briefing text still used the N64 offset +0xA000 -- inside the model.
After main menu -> back the model is not reloaded, so the overwritten
folder bodies/photos disappeared. Both now use +0x17000 (same 0x6e000
budget). User-verified; golden gate 3/3. D341 also user-verified.
Two fast3d defects. (1) The 1-cycle blood texture rectangle sampled a
stale tile-1 CI8 declaration: the title leaves G_TL_LOD set and the D236
detail-base rule redirected texunit 0 to tile 1. LOD tile selection is
2-cycle-only on the RDP, so texrects outside 2-cycle now sample their own
tile. (2) The drip image is regenerated in place in the dyn pool (reached
via the KSEG0 mirror); the address-only cache key froze it on its first
image. Dyn-pool textures now key on a content hash. Headless-verified,
golden 3/3. A/B: GE_DYNTEXHASH_OFF.
The IsWater 32x32 CI8 image (drawn through an RGBA16 tile, D229) was
imported with its mip chain as 32x43 and normalised as 16 wide, so the
pattern ran at 2x and wrapped every 43 rows instead of the N64's 32:
fold steps made it jump. Import the base level only and use CI8
geometry in the tri path. Sky/water fans now go through a port-only
G_FLOATVTX_EXT (float clip positions + S/T) instead of s16 Vtx, removing
the tc shift and wScale quantisation jitter. User-verified vs 1964;
golden 3/3; Win + Linux build. A/B: GE_D245_OLDVTX / GE_D245_OLDTEX.
The op-22 DisplayListPrimaryRecord count is the number of star-flash
arms; dorottex (and PD's modelRenderNodeStarGunfire) read count*4
vertices. d43_emit/d43_convert sized the array as count vertices, so
3/4 of every muzzle star came from neighbouring sidecar bytes and drew
as long spikes (M16 "shooting up"). Size it 16*4*count. Emitter
round-trip checks all pass; M16 renders a clean star headless.
Also TEMP GE_STARTWEAPON (bondview_r.c) for weapon repros. Re-run
tools_pc/d43_emit.py to regenerate data/pcmodels-*.
CCTVRecord's own s32 `pad` (the look-at pad) shadows the inherited
ObjectRecord `pad` (mount pad) under IDO. The PC struct renamed it
`lookpad` to satisfy GCC, which silently re-pointed setupCctv's reads at
the mount pad, so every camera's look vector was its lens offset and the
lens faced the wall. Read `lookpad` on PC (#ifdef PORT, A1 class);
matches PD's setupCreateCctv (lookatpadnum). User-verified vs 1964,
golden gate 3/3. Porting-notes gains the duplicate-member rename trap.
TEMP GE_D207S (gunfire.c, #ifdef PORT, read-only) logs every player
shot-sound decision (H1/H2/SKIP). Four user captures incl. a 7-weapon
stress test at 60 fps: 0 SKIP, 0 voice drops, audio production at rate.
The one captured drop-out ran under GE_AUDIOTRACE, whose audio-path file
I/O is a likely cause. Still open as intermittent.
optionsoverlay.c called atoi and lround through implicit int declarations
(GE's stub stdlib.h/math.h shadow the CRT, D324 class); atoi joins the
other K&R decls in port/shim/stdlib.h, lround gets a local prototype.
Windows + Linux builds clean of both warnings.
GE_INPUTSCRIPT gains ZHOLD/ZREL (sustained fire) for automatic-weapon
audio repros. D207/D241: headless burst-fire at 60 vs 30 fps with the
alarm forced logged zero voice drops at both caps; owed a real-play
capture. Golden gate 3/3.
D291 (user-captured) is D306: Dam intro camera 5, truck over the walkway
camera; reproduces at FovScale 100. All PC-specific leads refuted with
evidence: FOV, depth precision/DrawDistance, depth state (every truck
triangle is opaque z-tested), near-plane handling, wheel transforms. The
image is a depth-correct view of the authored model from under the truck.
GE_ZF's earlier "real fighting" was a +-255 z quantisation artefact.
TEMP tools: GE_INTROCAM=<n> pins the level intro's first camera
(bondview_r.c, #ifdef PORT, PRNG draw still consumed); GE_D306C depth-state
census in gfx_pc.cpp. Golden gate 3/3.
gimgSyncCompiledGlobalDLs (D68 shim) only copied texLoad's resolved
texture pointers into the compiled globalDL shadows while a slot still
held the 0xABCD IMAGESEG marker, i.e. only for the first stage (title).
Every later stage kept pointers into the title's freed texture pool, so
explosion smoke/fire/debris rendered as rainbow garbage once the stage
overwrote that memory (Facility: past the lockers). Learn the slots once,
re-sync them every stage. User-verified; golden gate 3/3.
Also: TEMP GE_D252POOL texpool/sync probe; GE_D157 F12 burst and caps
(uncapped colour match made live play 4-6 fps). D314 F10 flicker
user-confirmed fixed. Findings M-201, porting-notes C2.
- D252 (M-200): the 'rainbow confetti' is the explosion debris
(explosionInitFlyingParticles). Statically clean for colour; 4 headless
repros including the user's grenade-launcher trigger are all clean. Still OPEN.
- d320repro (TEMP): new explode= and cheat= actions for headless explosion
captures; documented in GE-ENV-PROBES.
- D314: optionsOverlayScroll (host thread) rebuilt s_visIdx/s_visN and wrote
s_sel while the scheduler thread draws the overlay. Wheel notches are now
queued atomically and applied in HandleInput (D287 pattern). Emit and
HandleInput share the scheduler thread. Headless file/mission select is
pixel-stable; likely fixed together with D287, needs a user check.
- D291: truck AI mapped (ai_9 / 0x040a, path 7); headless walk did not reach it.
input.c called SDL_SetRelativeMouseMode / SDL_ShowCursor from the scheduler
thread (every controller poll) and from the host thread's focus/click
handling at the same time. SDL's mouse API is not thread-safe; on Windows
relative mode starts/stops the raw-input thread, and clicking back into the
window after being unfocused is exactly when both threads flip it - the D287
freeze trigger. Callers now record the wanted state; inputApplyMouseRequests()
applies it on the host thread from videoPumpEvents(). Queue-deadlock leads
ruled out statically. Win+Linux build clean, golden 3/3; freeze re-test owed.
- front.c: constructor_menu07_missionsel / constructor_menu0D_missioncomplete
fall off the end while the caller uses the Gfx* result; return DL under
AVOID_UB (porting-notes D6). Old/new objects disassemble identically at -O2,
so no behaviour change on this compiler; clang/arm64 no longer rely on luck.
- libultra/audio/event.c: include <stdlib.h> under PORT so getenv() is not an
implicit int-returning declaration (D324 class).
- dram.c: DRAM_SIZE >> 32 on a 32-bit unsigned long (Win64) was UB.
Golden gate 3/3.
Four simultaneous drain monitors on the same USB interface: WASAPI (512 and
2048 samples) fell to 81-88% drain for ~30-50 s every ~317 s and lost 1.4% of
playback, while DirectSound stayed at exact real time. Each WASAPI shortfall
overflowed the audio queue and dropped blocks (the periodic garbled bursts).
audioInit() now hints directsound,wasapi; SDL_AUDIODRIVER still overrides.
Golden gate 3/3; 60 s GE_D204 run clean after load.
A no-game SDL drain monitor (new tools_pc/sdl_drain_monitor.c, opens SDL
exactly like port/src/audio.c) shows the maintainer's Focusrite USB interface
draining at 88-95% for ~15 s every ~312 s, matching the in-game overflow
bursts' period. Level loads, combat, the SDL pull pattern and a
pacemaker-vs-vsync beat were ruled out. Remaining D322 items: the 8-voice SFX
cap (D207/D241) and #87's progressive decay. porting-notes: measure the host
device before chasing periodic audio glitches.
D311 FIXED (root cause D336; 0 anomaly lines incl. Caverns combat), D288
CLOSED, D294 and D330 user-confirmed, D235 still unreproduced. D322: pools
healthy (leak hypothesis refuted); SFX soft-cap saturation in firefights
(D207/D241) plus a new periodic SDL output-queue overflow every ~314 s that
starts at the title screen, so it should reproduce headless.
Pins data/ge007.ini to a defaults-only 640x480 window (restored on any exit),
captures Bunker 1 at 640-1120:240 and runs framediff.py against the golden
baseline. --level/--dump give a capture-only smoke run (exit 0 = frames
captured and no crash). Full framediff output goes to scratch/.
New findings not covered by TCRF's articles (full detail in local
backlog/cut-content/RESEARCH.md):
- The shipped game's M16 pickup text still reads 'an AR33 assault rifle'
(LpropobjE PROPOBJ_STR_2A, propobj.c:10471); unused 'US AR33' strings and
PROP_CHRM16 comments survive too.
- Klobb rename scar verified: GUN_STR_6B is the only out-of-alphabetical-order
weapon name in LgunE.c, exactly as TCRF's prerelease page describes.
- cartrifle + wristdart: full pickup/prop resources, no ITEM_ enum, no weapon
stats — cut weapons missing from TCRF's unused-items list (wrist dart = the
AMMO_DARTS hardware; decomp comments it '(BETA)').
- All four Bonds mapped: CUFF_/BOND_ Connery/Dalton/Moore enums + the
actor-switch code in bondview2.c with every branch flattened to Brosnan;
no former-actor models exist in the ROM (80 C*Z chr models enumerated).
- Cuba (LlenE.c) is the only orphan level with recoverable text: cut Natalya
dialogue, title card, alternate credits cast.
- Orphan-level geometry confirmed present in ROM (obseg.h segment decls);
what's missing is mission setup, not geometry.
- Music enum vs Notes-page GS index aligned slot-for-slot through 0x2C with
four local mismatches past it (49/52/54/59) pending in-game audition.
Ammo (per-hand corner), bottom messages/title card (bottom-left) and top
dialogue (text origin) scale with crisp glyphs; dialogue and bottom
messages are width-capped because their line breaks are authored. 100%
emits nothing (golden 3/3). Captures verified at 150/200%; Win + Linux.
Env-gated per-frame timing: render phases, tris/batches, game-thread busy,
GL_TIME_ELAPSED GPU timer. Measured ~2.1 ms/frame total CPU on the heaviest
levels here; the GPU timer is only meaningful when GPU-bound. Target-hardware
numbers needed before a low-end preset. Golden 3/3; Win + Linux builds.
Scales the mouse accumulator's screen mapping and edge-scroll threshold; aim
entry adopts through the game's screen mapping so it never jumps. Measured:
PC 98%/72%, N64 65%/49%. Golden 3/3; Win + Linux builds.
- Input.AimMode 0=N64 (D332 PD-integration, default) / 1=Centred (PC); legacy
AimStyle/PdMouseAim migrated; hidden Input.AimLegacyGepd fallback.
- Mouse aim routing follows RMB/Aim, Q/L (the game's second aim button), and
insightaimmode (Toggle aim, pad): removes the accidental Q 'FPS aim'.
- The PD game hook only feeds the mouse while the mouse is the active aim
device, so pad/keyboard stick aim is not swallowed.
- Harness: GE_INPUTSCRIPT MDX/MDY/RHOLD/LHOLD/RREL + GE_AIMLOG; measured old
vs new: same screen range and edge-scroll, jitter equal headlessly.
Golden 3/3; Win + Linux builds.
bheadAdjustAnimation read player->field_5C0 / animFlipFlag, which on N64
are raw-offset aliases of the inline player.model (model.animframe1 /
model.gunhand). Since D100 made model a real inline struct on PC they were
separate, never-written fields: Bond's head-bob start frame came from
uninitialised player-struct bytes (2e32 etc.), poisoning his model anim
(D156) and wrecking the scene. The D294 2x room pool only moved the player
struct onto dirtier memory. Read/write the real model fields.
Found with gdb hardware watchpoints (field never written). Headless repro
Runway -> Frigate -> turn now clean, D156 0; golden 3/3; Win + Linux.
Verified at 16:9: -level_54 ending subtitles/cast roll keep their shape;
gun-barrel backdrop now clips at the 4:3 edge. Emitted only for windows
wider than 4:3. Win + Linux builds clean.
