D59/D64: the 'external 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 at ptr_logo_and_walletbond_DL+0x200. D60: osPiStartDma DMA-target validation (VirtualQuery-based) in libultra.c. D61/D63: TEMP env-gated ROM-read / VTX-pool / menu probes (strip list in HANDOFF Task 3). D62: OSMesgQueue/OSScMsg PC layout verification. D65/D65b: enum HEADS/BODIES signed sentinels under PORT (PC GCC picks unsigned underlying types; N64 semantics were signed). D66: romCopyAligned + ramrom replay 64-bit pointer width (s32 truncation of .bss targets > 4 GiB). D67: struct image_entry N64 layout reconstruction (dataoffset:24 first, all-u32 bitfields, sizeof==8). D68: Globalimagetable BE->LE fixup (port/src/gimgfixup.c): bswap the IMAGESEG-marked Gfx w1 words in the 17 ROM-copied DLs + sImageTableEntry. index in the 32 tables after texReset's romCopy; marker scan moved to bytes 6..7 under PORT; compiled globalDL shadows synced post-texLoad for explosion.c's g_ExplosionDisplayLists. Result: game boots, plays intro music, and renders the entire ~3.5-minute intro (logo -> gun barrel with Brosnan -> cast screen) at ~59 fps. New blocker D69: load_bg_file faults on first stage load - BG-file headers are N64 big-endian segment-0x0F offsets read LE on PC. Full analysis + strategy in PCPortResearch.md §F/D69; HANDOFF rewritten for the D69 session.

|
|
* N64 ROM model files are 32-bit-pointer big-endian images the PC build
|
|
* cannot read in place (D37/D43). tools_pc/d43_emit.py converts all of them

* offline to PC-layout RZ sidecars:
|
|
* data/pcmodels-<region>/pcmodels.bin single concatenated image
|
|
* data/pcmodels-<region>/manifest.csv name,offset,size (decimal)
|
|
*
|
|
* romdataInit reserves romSize + pcmodelsReserveSize() at CART_BASE and
|
|
* pcmodelsLoadSidecars() copies the sidecar image to [CART_BASE+romSize, ...).
|
|
* pcmodelsPatchTable() — called once from load_object_fill_header, after
|
|
* obInit() has run — redirects every model entry's hw_address into the
|
|
* extension region and sets rom_size to the PC compressed size, so the
|
|
* existing romCopy/decompressdata load path serves PC bytes unmodified.
