James Dansereau 181f6db07d PC port: phase 2 — D43 mechanical ABI edits + D46 buffer sizing + fast3d seg-5 case; converter spec validated (D47)

- bondtypes.h/model.c/chr.c/objecthandler_2.c/tex.c: PORT-guarded pointer-width
  and Gfx-size fixes (D43 step 2, uncommitted since prior session)
- front.c cast-screen bufferRemaining 0x1C000->0x25000, initmenus.c logo
  buffer 0x7C000->0x85000 (D46 strict bound)
- gfx_pc.cpp seg_addr: resolve raw 0x05xxxxxx via segmentPointers[5] + low24
  (unmarked segmented addresses, ROM convention)
- docs: D47 finding — converter contract finalized (compaction delta=R-P,
  accessors at 0x80090000, G_VTX GBI1 encoding, opcode-aware w1 remap rule,
  vertex formats, no embedded blobs, zero-vtx-array rule, staging contract,
  reload-hazard poolRemaining reset); HANDOFF rewritten around the remaining
  C implementation
- build-pc/d43_convert.py (gitignored, local): reference converter + validator —
  full N64->PC conversion spec run on all 512 ROM files, ALL CLEAN (max D_PC=0xB7E0)

fast3d — software RSP for the GE PC port

This directory will hold the software RSP: a C++ interpreter that consumes the Gfx display list the game builds and emits OpenGL calls, bypassing the N64 RDP entirely.

Source: adapt from the Perfect Dark PC port

The PD port ships a complete, working fast3d at perfect-dark-pc-port/perfect_dark/port/fast3d/:

File	Role	~Lines
`gfx_pc.cpp`	The RSP interpreter: matrices, lights, fog, tri1/tri4, vtx	2800
`gfx_opengl.cpp`	OpenGL backend: shaders, textures, zbuf, framebuffers	1300
`gfx_cc.cpp`	Color-combiner equation -> GLSL shader compiler	60
`gfx_sdl2.cpp`	SDL2 window-manager backend	460
`gfx_api.h`	Public API (`gfx_init/run/start_frame/end_frame/...`)	58
`gfx_pc.h`	Internal state (RSP struct, texture cache, combiner pool)	60
`gfx_rendering_api.h`	Rendering-API vtable (GL backend implements this)	61
`gfx_window_manager_api.h`	Window-manager vtable (SDL2 implements this)	54
`glad/`	GL loader	—

The PD fast3d already handles G_TRI4 (GE's 4-triangle command) — the PD game uses it too. So the bulk of the RSP work is done; we adapt, not rewrite.

GE-specific work to add

G_SETTEX (opcode 0xc0) — GE's custom texture-bank command (include/gbi_extension.h, gsSPUseTexture). Add a case in the gfx_pc.cpp dispatch and a corresponding texture-bank selection in the GL backend. Reverse the exact semantics from rsp/graphics/gmain.s + src/game/tex.c / initmttex.c.
Verify custom color-combiner modes — G_CC_MODULATEIFADE, G_CC_FADE, G_CC_DECALFADE, G_CC_BLENDRGBFADEA, etc. The gfx_cc.cpp compiler handles arbitrary CC equations; confirm each GE mode compiles to correct GLSL.
Verify the custom render mode — G_RM_CUSTOM_AA_ZB_XLU_SURF (AA_ZB_XLU with Z_UPD).
gDPLoadTLUT06/07 — map onto the existing G_LOADTLUT path.

Ground truth

rsp/graphics/gmain.s (repo root) is the real GE RSP ucode. We do not run it on PC, but it is the authoritative reference for the exact command encodings GE emits — use it to validate the software RSP's decoding.

Status

Empty (scaffolding). Populate during Phase 2 by adapting the PD fast3d and adding the GE-specific commands above.
