Building the PC port
Stages:
- Extract assets from your ROM (§2): a one-time step using the
decompilation’s own toolchain to pull levels, models, textures, fonts and
music into
assets/. (Only needed to regenerate the committed data files; a plaingit clonealready has what the PC build compiles.) - Build the port (§3): a CMake build compiling the game sources plus the
port/layer into a native executable. Needs no ROM. - Generate the PC asset sidecars (§4): two pure-Python converters turn
ROM model / stage data into the PC-layout
data/pcmodels-*/data/pccg-*files the port loads at runtime. Required to run.
You need a GoldenEye 007 N64 ROM you legally own (.z64, big-endian). See the
Requirements table in the README
for accepted versions and hashes.
1. Dependencies
Port build
The Windows (MSYS2 MINGW64) path is the primary one. The Linux build is compiled by CI on every push and ships in the release bundle (also playtested on Steam Deck hardware); the macOS column is best-effort guidance and has never been built or run there. Expect to fix build breaks yourself on untested platforms.

Asset extraction (decompilation toolchain)
The extraction scripts need binutils-mips-linux-gnu (or an equivalent MIPS
binutils), make, git, and python3. They build a small host-compiled
tools/extractor and slice blobs straight out of the ROM; no IDO / IRIX
toolchain is involved in extraction or in the PC build. (The IDO toolchain is
only needed to build the N64 ROM itself, and its proprietary SGI binaries are
not distributed here; see SetupGuide.md “Recompile IDO”.)
On Windows this is easiest under WSL or a Linux VM. Full details and
alternatives (Docker) are in SetupGuide.md.
2. Extract assets
Put your US ROM at the repository root as baserom.u.z64 (this name is
required by the extraction scripts; it is git-ignored and never committed),
then:
./scripts/extract_baserom.u.sh
For PAL or JP, additionally place baserom.e.z64 / baserom.j.z64 at the root
and run:
./scripts/extract_baserom.u.sh && ./scripts/extract_diff.e.sh # PAL
./scripts/extract_baserom.u.sh && ./scripts/extract_diff.j.sh # JP
(US extraction is a prerequisite for the others.)
This populates assets/ with the generated .bin blobs the build needs. See
SetupGuide.md for the in-depth build/asset pipeline.
3. Build
./build-pc.sh ntsc-final # or: pal-final / jpn-final
which is equivalent to:
cmake -S . -B build-pc -DROMID=ntsc-final
cmake --build build-pc -j
On Windows, build-pc.sh also locates the MSYS2 MinGW64 toolchain itself
(so it works from Git Bash or a non-login shell too, even with another
cmake earlier on PATH) and, if native child processes would get an
unwritable TMP, re-runs the configure+build under PowerShell with a
writable one. If MSYS2 is not installed at C:\msys64, set
GE_MSYS2_ROOT (e.g. GE_MSYS2_ROOT='C:\tools\msys64' for a custom
install location). Re-exec logs:
build-pc/ge007-native-reexec-*.log.
For PAL/JP you must first generate that region’s ROM-asset symbol file (the US one is committed):
python3 scripts/gen_romassets.py e # PAL -> port/src/romassets_e.s
python3 scripts/gen_romassets.py j # JP -> port/src/romassets_j.s
The executable lands at build-pc/ge007.x86_64 (.exe on Windows). PAL/JP
builds are named ge007.pal-final.x86_64 / ge007.jpn-final.x86_64.
4. Generate the PC asset sidecars (required to run)
The port does not read model geometry, stage bg/stan data, or per-level
setup data from the raw ROM at runtime; it reads them from PC-layout sidecar
files under data/, produced offline by three converters. Without them the
game shows the intro logos and then crashes in
modelPromoteNodeOffsetsToPointers (finding D179) or on the first level load
(missing stage setup).
Put your ROM in data/ first (same file the game runs from):
mkdir -p data
cp /path/to/your/rom.z64 data/ge007.ntsc-final.z64 # or pal-final / jpn-final
Then run all three emit passes for that region, in this order (d88 appends to d69’s output):
python3 tools_pc/d43_emit.py ntsc-final # -> data/pcmodels-ntsc-final/{pcmodels.bin,manifest.csv} (~1.3 MB)
python3 tools_pc/d69_emit.py ntsc-final # -> data/pccg-ntsc-final/{pccg.bin,manifest.csv} (bg + stan)
python3 tools_pc/d88_emit.py ntsc-final --regen # appends the 21 solo Usetup*Z + 13 multiplayer Ump_setup*Z stage-setup files -> ~3.6 MB
PAL / JP note: both regions convert, build and boot from source (finding
D258, fixed 2026-10-02; D487/D488 fixed the PAL frame height and TV type).
Run the three emit passes with pal-final or jpn-final, and build into a
separate directory, for example BUILD_DIR=build-pal ./build-pc.sh pal-final.
Release packages are still NTSC-U only until per-region packaging lands
(issue #85).
These are pure-stdlib Python 3 (no MIPS toolchain, independent of the
step-2 asset extraction) and read only the ROM plus files already committed to
the repo (scripts/filelist.u.csv, assets/obseg/file_resource_table.inc.c,
assets/**/ModelFileHeader.inc.c, the bg/stan .inc.c). Output is a
deterministic function of the ROM. Re-run after any change to d43_emit.py /
d69_emit.py / d88_emit.py or the model/bg converters (d43_*, d69_*,
d88_propdefs.py).
The release bundle ships the same converter frozen as
prepare-assets/ge007-convert; the game spawns it on first launch when the sidecars are missing, so end users never run it by hand. See the bundledREADME.md.
data/pcmodels-*/anddata/pccg-*/are gitignored ROM-derived game data; never commit or redistribute them.
5. Run
./build-pc/ge007.x86_64 # run from the repo root
The ROM in data/ (from step 4) and the sidecars are both required at
runtime. ge007.ini is written under data/ on first launch.
Useful flags / env
-level_NN |
boot straight into a solo level (e.g. -level_09 = Bunker 1) |
GE_PCDUMP="first-last:step" |
dump rendered frames as PPM (debugging) |
