#GoldenEye 007 PC Port

A native PC port of GoldenEye 007 (Rare, 1997, Nintendo 64), compiled from the GoldenEye 007 decompilation: the original N64 game running from reconstructed source, not the Xbox 360 remaster. The N64's graphics coprocessor (RSP) is emulated in software; every other hardware surface (video, audio, input, timers, save storage) is shimmed in a dedicated port/ layer, following the architecture of the Perfect Dark PC port, the same Rare "Indy" engine family, one hardware generation apart.

v0.3.0 is out for Windows and Linux (including Steam Deck, where the Linux bundle sideloads as-is) and runs the full campaign at a steady 60 fps with known rough edges (Status). Free to download, build on and modify (you bring the ROM).

This is a pre-1.0 release, not a finished product. v1.0 is the target for a polished, feature-complete build; until then, expect rough edges, missing features, and breaking changes between versions. See Status for what works today and Roadmap for where this is headed.

AI disclosure: development here was agentic - Claude Pro plus a local open-weight model on a single RTX 5090, as of August–September 2026. This project is as much a study of that process as it is a port: whether current LLMs can carry a codebase like this, and what actually goes wrong along the way. Judge the result for yourself. I'm one person doing this in my spare time, not a team. See Background for the full setup, timeline, and an honest account of what worked and what didn't.

[!IMPORTANT] You must supply your own GoldenEye 007 ROM. This repository contains no Nintendo code or assets, and no ROM. Nothing here is distributable as a playable game: see Requirements and Legal.

All in-engine, running in the port — a ~12 s gameplay montage from live v0.3.0 play sessions.

#Download

Both bundles contain no ROM and no game assets: you supply your own (see Requirements), which keeps the release legal to distribute. Earlier builds: v0.2.2, v0.2.1, v0.2.0, and v0.1.0 alpha, same page. You can also build it yourself; see Building.

#Quick start

You need a GoldenEye 007 N64 ROM (.z64, big-endian). This release supports the NTSC-U (US) version; PAL and JP are on the roadmap (issue #85). No ROM or game asset is included or distributed. Then:

1. Download the Windows or Linux bundle from Releases and unpack it.
2. Make a data/ folder next to the executable and drop the ROM in as ge007.ntsc-final.z64.
3. Launch the executable from that folder. The first run takes a few extra seconds: it detects the ROM and generates the derived asset folders once (no Python or other tooling needed).

Read the Status caveats first: v0.3.0 has known rough edges, listed plainly there.

#Status

v0.3.0 - playable, with known rough edges. The full single-player campaign is completable end to end (all 20 missions, Agent difficulty, playtested), at a steady 60 fps; all 20 solo missions — plus the end-of-campaign credits sequence — load, render and run crash-free, verified on Windows, Linux and real Steam Deck hardware. Feedback is very welcome.

What a release actually installs (no networking, no telemetry, no ROM or game assets shipped) and how faithfully the port tracks the original N64 game's logic: Security & fidelity status.

Working: boot sequence and front end (menu → mission select → briefing → start), front-end menu navigation on the left stick to match the F10 overlay (D282); all 20 solo missions load, render and are crash-free (full campaign playtested end to end at Agent difficulty, including the ending sequence); steady 60 fps (software RSP off the presentation critical path); full audio: in-level music and SFX; keyboard + mouse (click-to-lock, proportional aim mode, a single simplified sensitivity control) and a modern dual-stick controller layout; automatic widescreen FOV scaling; Bond is fixed in cutscenes (no more floating or spin-glitching) and his third-person model positioning generally is right the large majority of the time now, at most a small drift when off; file-backed saves; faithful N64 progression by default (F10 → All unlocked opens every level, 007 mode and the full cheat menu); F10 in-game options overlay (resolution, frame cap, MSAA, filtering, FOV, sensitivity); Windows and Linux, including Steam Deck.

Known issues:

• Particle colours: a real fix landed (a corrupted-vertex-buffer bug), but the rainbow effect can still occur intermittently on either platform, not every time or on every level — a second cause hasn't been found yet (D252).
• Some muzzle flashes draw an extra, erroneous long flash straight up from the gun (seen on the M16, among others), overlaid on the normal, correctly drawn flash. Cosmetic only (D303).
• Water levels show a moving seam between two water patterns (D245).
• Occasional z-fighting on some levels' geometry (D308) — a Dam intro/ truck-wheel instance showing odd transparent-looking areas may be related (D306). Minor and cosmetic.
• In-level security camera props (not the player's own view) can occasionally end up facing backwards on some levels, seen on Bunker (D307).
• Rarely, Bond's model can briefly render out of place after an animation transition — purely visual: no effect on gameplay or saves, and it clears on its own or by re-entering the level (D311).
• On Facility, if gas leaks during Ourumov's monologue he can pause for up to ~10 s before resuming the scripted shootout — a latent race that exists in the N64 original too (where it softlocks permanently); the port detects and auto-recovers it (D318).
• Some front-end 3D models are off: the spinning Nintendo logo renders as two white blobs and the Rareware logo's texture filtering looks wrong (D75).
• Surface 1's 2D billboard trees render as a solid wall of tree texture instead of discrete sprites (D236). Under active investigation.
• Widescreen is stretched, not native: on non-4:3 windows the whole frame (world and HUD) is stretched horizontally to fill your display — about 33% wider than original at 16:9, like a 4:3 video in a TV's "stretch" mode. Automatic FOV scaling keeps the framing comfortable and gameplay is completely unaffected (all game logic runs in world space), but shapes are subtly wider than on the N64 — most visible on round objects (barrels, the radar). A distortion-free native widescreen render is on the roadmap.
• Distant geometry can drop out on the biggest open levels (Streets, Egyptian) at default FOV — a culling/LOD issue that sometimes self-corrects as you keep moving (D249).
• Gunshot SFX can sound off during sustained/rapid fire: cadence can drift from the N64 original's rate, and PP7/AK47 fire can occasionally go silent under heavy automatic fire near another looping sound (D240/D241).
• All unlocked is highly experimental — don't enable it until you have at least one save written (complete a level normally first, e.g. Dam on Agent). Enabling it on a brand-new install with no prior save can still cause silent audio and odd right-mouse-aim behavior (D257/D259/D281).
• Assorted further cosmetic defects are tracked in docs/dev/GRAPHICS-BACKLOG.md.
• No macOS or ARM support; no controller rebinding UI.

#Steam Deck

The Linux bundle is the Deck build. SFTP it over from your PC, or download it straight from the releases page on the Deck itself: unzip, drop your ROM in data/, launch it once (the first run generates the derived assets), and add the executable as a non-Steam game. SDL2 is bundled, so no dependencies need installing. On SteamOS the first launch seeds ge007.ini with Deck-friendly defaults: native 1280×800 fullscreen, VSync, MSAA 4, and 150% draw/LOD distance (the authored N64 fade distances read short on the close-up panel); everything is changeable in the options overlay and persists afterwards. Do that first launch in Game Mode, not Desktop Mode — an ini created by an earlier Desktop Mode launch (e.g. while testing before adding it as a Steam shortcut) permanently skips the Deck preset, since any existing ini always wins over it (D283). If your resolution isn't 1280×800 on first Game Mode boot, just set it manually: F10 → Resolution. The renderer is CPU-bound (software RSP); expect original N64-era performance at 60 fps rather than more. This release was playtested on real Deck hardware; the v0.1.0-era Facility crash (D203) did not recur: its root cause was identified and fixed (D253), and a separate intermittent SIGSEGV in heavy firefights/terminal destruction (D255) and an audio-thread crash (D305) are both fixed and live-verified on real hardware as of this release.

In-game settings on the Deck. The options overlay is fully gamepad-driven: it opens with Select, the D-pad or left stick (up/down) moves between options, A steps the selected option forward, B steps it back, and Start (or Select again) closes. Toggles flip, resolution / MSAA / filtering cycle, sliders step in increments. With a keyboard attached the same overlay is F10 + arrows/Enter.

#Roadmap

No fixed timeline or committed feature list — this is spare-time work — but directionally, on the way to v1.0:

• Working through the known issues above and the fuller list in docs/dev/findings.md.
• PAL and JP ROM support (issue #85); NTSC-U is the only supported region today.
• Native widescreen — a distortion-free render at your display's aspect (correct-aspect projection and a wide-frame HUD), replacing today's stretched 4:3 frame + FOV compensation.
• Controller rebinding UI, and macOS/ARM builds.
• LAN multiplayer: reviving GoldenEye's original split-screen/deathmatch netplay across multiple PCs on a local network. Genuinely under consideration, but early and not started; no ETA.
• General polish: performance, remaining rendering/audio defects, save/config robustness.

Not currently planned: new game modes GE never shipped (e.g. co-op), online (non-LAN) multiplayer, ray tracing. If any of these matter to you, open an issue — it helps prioritize.

#Beyond playing

• Tweak it: ge007.ini and the F10 in-game overlay expose resolution, frame cap, MSAA, texture filtering, FOV/draw distance and mouse feel; launch with -fresh for a clean-slate run.
• Read it: docs/internals.md maps the architecture and the software RSP; docs/porting-notes.md is the catalogue of N64→PC bug classes hit along the way. Game logic in src/ is unmodified decompilation; every hardware surface lives in the MIT-licensed port/ layer.
• Mod it: the port layer, build system and tools_pc/ are yours to extend (see License); CONTRIBUTING.md has the ground rules for getting changes in, and docs/dev/ is the raw engineering record behind every fix.

#Background

The port was built by two coding agents, a local open-weight model (unsloth/Qwen3.8-27B-GGUF on one RTX 5090, via the pi agent) doing the groundwork (build, boot chain, software-RSP integration, asset pipeline, first frames), and Claude Code (Sonnet 5, Opus 5 for the hardest bugs) joining for the collaborative phase (the 21-level sweep, the ABI finding catalog, SDL input, front end), handing work back and forth through shared written notes, directed by one person part-time. In short: 36 days (16 Aug – 20 Sep), ~835 commits, 199 findings root-caused and logged (D1–D321).

The full write-up (timeline, handoff mechanism, effort breakdown, an honest "what worked / what didn't"): docs/dev/agentic-development.md. The workflow itself: docs/dev-process.md. To cite the project or its findings: CITATION.cff (GitHub's "Cite this repository" menu).

#How this differs from the other GoldenEye PC projects

This is a native port of the original 1997 Nintendo 64 game, built from its actual reconstructed source code, the same lineage as the Perfect Dark PC port. The other well-known "GoldenEye on PC" projects are something different: they machine-translate the shipped binary of the unreleased Xbox 360 XBLA remaster, a different game on a different codebase with no shared code with this one.

They answer a different question: how to get the remaster onto PC by machine translation. This project answers how to get the original 1997 game onto PC, running from its reconstructed source.

#Requirements

You need a GoldenEye 007 (Nintendo 64) ROM that you legally own, in big-endian (.z64) format, matching one of:

This release supports the US (NTSC-U) version; PAL and JP ROMs are recognised by region but not yet supported (on the roadmap, issue #85).

The port also relies on the decompilation's asset-extraction step, which pulls the level, model, texture and music data out of your ROM at build time. That step, too, requires your ROM and is part of Building.

#Building

Prerequisites: CMake >= 3.16, a C/C++ toolchain, SDL2, zlib, OpenGL, Python 3, plus the decompilation's own build dependencies (an IRIX MIPS toolchain via qemu-irix, used only for the one-time asset extraction). See docs/building.md for the full walkthrough and the asset-extraction details.

#Windows (MSYS2)

# in the MINGW64 shell
pacman -S mingw-w64-x86_64-toolchain mingw-w64-x86_64-SDL2 \
          mingw-w64-x86_64-zlib mingw-w64-x86_64-cmake \
          mingw-w64-x86_64-python make git

git clone https://github.com/jkdansereau/goldeneye-pc-port.git
cd goldeneye-pc-port
# 1. extract assets from your ROM (see docs/building.md)
# 2. build the port
./build-pc.sh ntsc-final         # NTSC-U; PAL/JP engine builds compile, but their asset sidecars are not yet producible (issue #85)

#Linux

The Linux build is compiled on every push by CI (ubuntu-24.04); the release bundle additionally bundles SDL2 so no system packages are needed at runtime.

sudo apt install build-essential cmake python3 libsdl2-dev zlib1g-dev libgl1-mesa-dev
git clone https://github.com/jkdansereau/goldeneye-pc-port.git
cd goldeneye-pc-port
# extract assets (docs/building.md), then:
./build-pc.sh ntsc-final

The executable is written to build-pc/ge007.x86_64 (on Windows, build-pc/ge007.x86_64.exe).

#Running

1. Create a data/ directory in the repo root.
2. Put your ROM in it, named as in the table above (e.g. data/ge007.ntsc-final.z64).
3. Run the executable from the repo root: ./build-pc/ge007.x86_64.

Configuration is written to ge007.ini on first run; game progress lives in ge007.eep. Launch with -fresh to wipe both before starting (a clean-slate run for playtesting).

#Default controls

The controller layout follows the modern dual-stick scheme used by the console re-releases (left stick move, right stick look, triggers fire/aim, shoulders cycle weapons).

Mouse sensitivity, Y-inversion and the aim/turn split are tunable in the [Input] section of ge007.ini.

#How it works

The R4300 game code in src/ is compiled completely unmodified; the decompilation's control flow is ground truth. Everything that would touch N64 hardware is redirected into port/: a software RSP (port/fast3d/, adapted from the Perfect Dark port) that interprets the GBI display list the game builds each frame and emits OpenGL, bypassing the RDP; a scheduler replacement (port/src/gesched.c) that drives it directly; single-threaded libultra OS shims (port/src/libultra.c); and SDL2/OpenGL/filesystem backends for video, audio, input and storage. The 32→64-bit transition forces a small, cataloged class of mechanical ABI-only edits to ROM-serialized structs (pointer-width reconciliation); these change no behavior and are documented individually. Where it diverges from the Perfect Dark port: GoldenEye's N64 serialized asset formats are converted offline by Python "sidecar" converters in tools_pc/ rather than fixed up at load time. Full detail: docs/internals.md and docs/porting-notes.md.

#Credits

This port is a thin layer on a large amount of other people's work.

Prior work it is built on

• The GoldenEye 007 decompilation, years of effort by Larry Ficken ("kholdfuzion") and the project's contributors; plus zoinkity's GoldenEye documentation, which the decomp started from. This port is a fork of that repository.
• The Perfect Dark PC port (Ryan Dwyer and contributors), the reference architecture for this port and the source of the fast3d software RSP.
• The Perfect Dark decompilation, the sibling decomp the PD port is built on.
• Carnivorous: author of the Mouse Injector input plugin for 1964 (the "GEPD Edition" bundle). Its mouse-aim behaviour for GoldenEye/Perfect Dark is what the in-game GEPD-style aim mode is modelled on; the implementation here is an independent reimplementation of that behaviour, not derived code. Thanks also to Rice and schibo of the 1964 team for the emulator it shipped with.

Vendored / adapted code

• port/fast3d/: the software RSP, adapted from the PD port. It originates with the Ship of Harkinian / libultraship fast3d (© Emill, MaikelChan; MIT, see port/fast3d/LICENSE.txt), which itself descends from sm64-port's fast3d and audio mixer.
• port/fast3d/glad/: OpenGL loader generated by glad (David Herberth, MIT).
• The decompilation toolchain: ido-static-recomp (Emill / decompals), qemu-irix and rabbitizer (n64decomp).
• SDL2 and zlib.

Methodology

• Chris Lewis, "Decompiling a Nintendo 64 Game in 84 Days" (the Snowboard Kids decompilation write-up), the agent-workflow practices in docs/dev-process.md are adapted from it.

Consultation

• f1zz1ec0ke (GitHub): LLM consultation on model tuning, agent harnesses, and agentic strategy throughout the port's development.

Tools and models used to develop the port

• Qwen 3.8 (Alibaba Qwen team), run locally from the unsloth/Qwen3.8-27B-GGUF repo — UD-Q4_K_XL as the primary quant, with other quants used along the way; Unsloth (the GGUF quantisation and Unsloth Desktop) as the local model server.
• pi: the local coding-agent harness.
• Claude / Claude Code (Anthropic).

#Legal

This is a non-commercial fan preservation/research project, in the same category as the many other N64 decompilation and native-port repositories on GitHub. It follows the same conventions they do:

• No ROM and no game assets are distributed: not in this repository and not in any release. Textures, audio, models, level data and in-game text are extracted from a ROM you already own, on your machine, at build time.
• The repository is a fork of the public GoldenEye 007 decompilation and inherits its contents unmodified (see NOTICE for what that includes).
• No official logos, box art, or marketing assets are used. "GoldenEye 007", "007", "James Bond" and related marks belong to their respective owners (Nintendo, Microsoft/Rare, MGM, Danjaq, EON Productions).
• Pre-built binaries published under Releases contain only the engine (the port/ layer plus the compiled decompilation, with no game data of any kind), bundled with permissively-licensed runtime libraries (SDL2, zlib, the MinGW runtime; their licenses travel in the download). Any build, yours or ours, is useless without a ROM you supply.

This project is not affiliated with, endorsed by, or sponsored by Nintendo, Rare, Microsoft, MGM, Danjaq, EON Productions, or any rights holder in GoldenEye or James Bond. If you are a rights holder with a concern, open an issue and it will be addressed.
