- README, LICENSE (MIT for the port layer), NOTICE, CONTRIBUTING. - Restructure docs: internals.md, porting-notes.md, dev-process.md + dev/agentic-development.md (the research write-up), dev/ (raw record). - Replace decomp status-badge CI with a PC-port validate workflow. - Remove session/agent scaffolding and stale planning docs from the tree. - Add .gitattributes (normalize line endings to LF); add screenshots. The pre-2026-08 history is the GoldenEye 007 decompilation by Larry Ficken (KholdFuzion) and contributors, preserved unchanged. The PC-port work from 2026-08-17 on is mine.

/*
|
|
* GE adaptation header for fast3d (see docs/internals.md).
|
|
*
|
|
* fast3d was written against Perfect Dark's extended GBI set
|
|
* (pd_port/src/include/gbiex.h + PD's include/PR/gbi.h). GoldenEye shares the
|
|
* same Rare "Indy" engine family but its extension header is
|
|
* include/gbi_extension.h, which defines G_TRI4 (0xb1) and GE's custom
|
|
* combine/RM modes — but NOT the PD-specific opcodes below.
|
|
*
|
|
* GE never emits the PD-only opcodes (its RSP ucode is rsp/graphics/gmain.s,
|
|
* which has no handling for them), so the corresponding dispatch cases in
|
|
* gfx_pc.cpp are dead code for this port; they only need to COMPILE. The
|
|
* values mirror PD's gbiex.h exactly so that if a ROM ever does emit one,
|
|
* behaviour matches the sibling port rather than hitting the fatal "unknown
|
|
* opcode" path.
|
|
*
|
|
* G_COL (7) is "new in PD": GE fills vertex colours directly in Vtx.cn[]
|
|
* and its ucode has no colour-table DMA, so that case is dead here too.
