Yes: JackTulli’s fan-made Halo 64 brings Halo: Combat Evolved multiplayer to a real Nintendo 64. It is built from the halo-ce-universal decompilation, with a new N64 renderer, menus, HUD and sound layer created with libdragon and tiny3d.
This is more than a visual demake. The port carries over Halo’s weapons, physics, collision, game rules, first-person arms, objects and pathfinding, then converts map data from the player’s own Xbox game files during the build. The main release is multiplayer-focused; the separate campaign cartridge is an incomplete experiment rather than a finished replacement for the Xbox game.
What Halo 64 actually is
The project adapts Halo: Combat Evolved’s gameplay systems to the Nintendo 64’s VR4300 processor. Its platform layer handles N64 input, rendering, particles, sound, animation streaming, menus and exception behavior, while the game logic comes from the decompiled Halo codebase.
Recognizable details remain: shields, health, ammunition and motion-sensor HUD elements; weapon and vehicle sounds; menu music; multiple control schemes; Rumble Pak support; and settings saved to EEPROM. Assets are not taken from a prebuilt retail ROM. The builder converts maps from an Xbox copy or image supplied by the user.

Firefight
A separate Firefight option sends Grunts, Jackals and Elites onto the multiplayer maps in waves. It supports one to four players, shared lives and four difficulty settings, giving the cartridge a cooperative mode without requiring the campaign.
Rank #3
- Control a character during massive firefights as you eliminate as many Covenant soldiers as possible
- Engage in guerilla warfare against the enemy, using whatever is at your disposal on the station
- Use your tactics skills to command squads and eliminate the enemy
- Role-based team & multiplayer combat with over 25 characters onscreen at a time
- A wide variety of vehicles & locations designed in perfect detail
Is the full Halo campaign included?
Not in the main multiplayer release. The repository also documents a separate campaign cartridge containing the “Halo” level, Marines and Covenant with simplified artificial intelligence, checkpoints, four difficulty settings and the Warthog.
That campaign build is explicitly incomplete: it has no cutscenes or scripts, and the level’s second BSP section is not included yet. It is best understood as a technical demonstration of campaign systems, not a complete playable port of the Xbox adventure.
Rank #4
- Disc only. Original case and manual not included. Will come packaged in a generic case.
- This renewed game has been cleaned, tested, and shows minimal wear.
How an Xbox-era game fits on N64 hardware
The hardware gap is enormous. JackTulli’s 2026 repository comparison lists the N64 at 93.75 MHz and 8 MB with the Expansion Pak, versus 733 MHz and 64 MB for the Xbox.
| System | CPU figure cited by the project | Memory figure cited by the project | What that means for this port |
|---|---|---|---|
| Nintendo 64 | 93.75 MHz VR4300 | 8 MB with Expansion Pak | Requires aggressive streaming, culling and scheduling |
| Original Xbox | 733 MHz | 64 MB | Has substantially more processing and memory headroom |
Halo’s game ticks still run at 30 per second, but less important work is scheduled less often. Distant or inactive objects and AI receive fewer updates, reducing CPU load while preserving the main simulation.
Best Value
- Master Chief can now wield two weapons at once, board Covenant vehicles and steal Covenant weapons like the incredible double energy sword
- Lead an all-new unit of super-soldiers, the ODST -- tougher, badder and deadlier versions of your old comrades
- New enemies, allies and surprises around every corner - intense combat action with enhanced AI and real-time lighting
- Immense single-player action with maassive landscapes and huge cities to explore and defend - destructible and interactive environments
- Take the action online with your Xbox Live and switch sides, to become a Covenant Elite!
Maps are converted into a big-endian format suited to the N64. Models, textures and animations stream from the cartridge, and reduced texture formats lower memory pressure. The renderer uses tiny3d batches, baked lighting, culling and per-view HUD recording. Render cost changes with the map, number of split-screen views and bot count, so the project provides an FPS-counter setting rather than claiming one universal frame-rate result.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What you need to run Halo 64
- An original Xbox copy or image of Halo: Combat Evolved. The builder converts the maps locally, and the repository contains no retail game data.
- An N64 Expansion Pak for original-hardware play.
- A compatible N64 flash cartridge to load the resulting
.z64image, or an accurate emulator. The project documents ares as its emulator option. - A build environment: the repository supplies a Windows ROM Builder and separate Linux/WSL build instructions.
A source build produces a ROM of roughly 63 MB according to the project README. That size is another reason an ordinary cartridge dump or stock memory setup is not enough.
Build-and-play workflow
- Obtain your own legal copy or image of the Xbox game.
- Install the project’s Windows ROM Builder, or follow its Linux/WSL instructions.
- Provide the Xbox game files when the builder requests them. The tool converts the maps and packages the N64 data locally.
- Build the multiplayer or campaign cartridge you want. The resulting image uses the
.z64format. - Run the image in ares or transfer it to a compatible N64 flash cartridge.
- For original hardware, install the Expansion Pak and connect one controller per active split-screen player.
The repository’s stated workflow is to build the ROM yourself and keep the resulting image private. It does not distribute a prepacked copy of the retail game.

- Scope: multiplayer is the mature, feature-complete target; campaign functionality is a separate incomplete cartridge.
- Visual detail: reduced texture formats, baked lighting and culling make the maps fit the N64’s memory and rendering limits.
- Simulation: the core tick rate remains 30 per second, while distant objects and AI update less frequently.
- Split screen: one to four views and bot counts directly affect rendering and processing demand.
- Assets: the build depends on user-supplied Xbox files instead of redistributing commercial game data.
How it compares with playing Halo on Xbox
| Category | Halo 64 on N64 | Original Xbox version |
|---|---|---|
| Primary scope | 13-map multiplayer cartridge; separate incomplete campaign cartridge | Full released campaign and multiplayer package |
| Local players | One to four split-screen players | Original Xbox feature set |
| Maps and assets | Converted from the player’s Xbox files at build time | Native retail assets |
| Hardware | N64 with Expansion Pak, flash cartridge or emulator | Original Xbox hardware |
| Performance behavior | Varies with map, views and bots; an FPS counter is provided | Runs on the platform for which the game was released |
| Data distribution | User builds locally and keeps the ROM private | Retail game media |
Why the port matters
Halo launched on hardware with far more CPU and memory than the N64, yet this project preserves the game’s underlying rules rather than merely imitating its appearance. Getting weapons, collision, vehicles, HUD behavior, bots, sound and multiplayer modes working together requires a complete platform layer and careful control of memory and update time.
The result is therefore best judged as a working N64-era multiplayer conversion with unusually broad systems coverage. It is not a full replacement for the Xbox campaign, but it demonstrates that recognizable Halo gameplay can run on a machine never designed to host it.
