A 23-player Halo: Combat Evolved match was reported running on an Anbernic RG35XX H because the handheld was not emulating an Xbox. It was running an unofficial ARM64 port based on the OpenCE community decompilation project. The project’s author, kirklandsig, reported joining a public Blood Gulch Slayer match with 22 other players and seeing 50–60 frames per second, mostly 58–60. Those figures describe one developer-reported setup, not a verified performance guarantee or a demonstrated maximum player count.
What happened in the 23-player match?
The specific demonstration used an Anbernic RG35XX H, a handheld built around an Allwinner H700 processor and Mali-G31 GPU. The project author reported joining a public Blood Gulch Slayer game alongside 22 other players. Notebookcheck described the same 23-player match on October 8, 2026.

That is evidence that this particular build could connect to and run in a crowded public match on this particular handheld. It does not establish that 23 players is the game’s normal official capacity, the port’s tested maximum, or a reliable player count for every session. Nor does it provide a broad measurement of matchmaking availability, network latency, or performance across different devices.

The author reported 50–60 fps during the match, with the rate mostly between 58 and 60 fps. Treat that as a report from one setup, not an independent benchmark. The project repository also gives separate campaign and menu measurements under specified conditions; those should not be mistaken for multiplayer results. A frame-rate number from a different mode or test does not prove what another player will see in a public match.

Is Halo running through Xbox emulation?
No. The demonstrated setup is a native port, not an Xbox emulator. The project author says, “There is no emulation: no xemu, no Box64, no Wine.” In this context, “native” means that the project adapts and compiles game code to run on the handheld’s ARM64 processor rather than recreating the Xbox hardware in software.
Decompilation and a native port are different steps
Decompilation is the process of reconstructing source code from a compiled program. OpenCE is the community decompilation project on which this port is based. The handheld port then adapts that reconstructed game code and its supporting software to a different processor and operating environment. Decompilation alone does not mean a game is ready to run on another device; the porting work is what makes the code usable on the target system.
The repository describes an ARM64 host program that loads the game’s compiled image, connects SDL calls to the handheld firmware’s SDL2, and routes graphics work through an OpenGL ES path focused on Mali hardware. In practical terms, the project is translating the game’s expectations about its platform into interfaces the handheld can provide. That differs from an emulator, which models the original console’s hardware and runs software as if it were executing on that console.

The distinction matters because it explains both the performance story and the limitations. The match did not show that an RG35XX H can emulate an Xbox at that speed. It showed a community project running adapted game code on compatible H700 hardware. The project is unofficial and does not imply endorsement by Microsoft, Bungie, or Halo Studios.

How does the networking work?
The online play in the demonstration came from the OpenCE build. Project documentation describes browsing public games, hosting and joining over the internet or a local network, and network campaign co-op with compatible OpenCE builds. The author specifically reported testing a join to a public match—the 23-player Blood Gulch game.
That distinction is important when describing what has actually been demonstrated. The cited update does not say the author tested hosting a match from the handheld or playing an online campaign co-op session on it. Those features are described by the project, but they should not be presented as part of the same verified handheld test. Connecting successfully once also does not establish how stable a session will be on another network or at another time.
OpenCE compatibility is the key condition: the project describes play with compatible OpenCE builds on PCs or other handhelds. It is not a claim that this port joins every version of Halo: Combat Evolved multiplayer or that every platform’s networking setup is interchangeable. The available account does not include a latency dataset or a multi-device study, so it cannot support conclusions about typical ping, lag, or the experience across a wider population of players.
How this differs from playing through xemu
xemu is an Xbox emulator and offers a separate route to playing Xbox software. It was not used for the RG35XX H match. Its networking options help illustrate why “Halo on a handheld” does not automatically mean “Xbox emulation on a handheld,” but the two approaches are different systems and their results should not be compared as if they were the same test.

| XLink Kai | A peer-to-peer service for LAN-based gaming over its network; it is separate from the OpenCE port. | Its service connects players for supported LAN-based games. | The fact that XLink Kai exists does not establish that it was used in the handheld Halo CE match. |
xemu network modes are a separate setup
xemu documents NAT, UDP Tunnel and Bridged Adapter as its network backends. UDP Tunnel encapsulates traffic to create a virtual LAN among xemu users. Bridging can connect emulated Xbox networking to a real Xbox on a local network or to a service such as XLink Kai. The xemu documentation cautions that Wi-Fi bridging may not work as expected: some access points and clients do not support multiple MAC addresses per connection.
Team XLink describes Kai as a peer-to-peer service for LAN-based gaming over its network. Its live homepage lists Halo 2 as an active Xbox game, but that does not show that Kai was used for this Halo CE match. Keep these tools in their own context: they can be relevant when discussing Xbox networking, but neither is evidence for how the OpenCE demonstration connected.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What hardware and game files are required?
The port targets handhelds based on the Allwinner H700, and the repository identifies the RG35XX H as tested. That is narrower than saying it works on any retro handheld. The repository’s compatibility notes distinguish devices that are tested from those with user-reported results, those expected to work, and those not tested. A list of possible devices is not a guarantee that every model, firmware release, or installation package behaves the same way.

The project release does not include the game itself. Its instructions require the user’s original Xbox copy of Halo: Combat Evolved, specifically a North American or European Xbox disc image or the required extracted Xbox maps. PC-version game files do not work with this setup. The repository says to allow about 3 GB of free space on the card for extracted map data, the game’s initial cache, and temporary room for the disc image during setup.

- Software: a compatible port release and firmware. The captured instructions target Knulli hardware and also describe releases for Knulli and PortMaster; check the project’s current documentation for the package and firmware combination that applies to your device.
- Game data: your own compatible North American or European Xbox disc image or extracted Xbox maps. The release does not bundle these files, and PC game files are not interchangeable for this setup.
- Storage: about 3 GB free on the card, according to the project repository.
What should you check before attempting installation?
Firmware and packaging instructions can change, and compatibility is specific to the combination of device, firmware and release. Rather than applying steps written for a different handheld, check the live project documentation and release notes for your exact model. The repository’s captured instructions focus on H700 devices and Knulli, with PortMaster releases also described; that does not establish that every firmware image supports every package.
- Confirm the handheld’s processor. Check that your model is an H700-based device before treating the RG35XX H instructions as relevant. A similar-looking handheld is not necessarily compatible.
- Match the package to the firmware. Use the project’s current guidance for the installed firmware and its Knulli or PortMaster release. Do not assume a package for one firmware can be installed unchanged on another.
- Prepare compatible original game data. The project requires Xbox-version files from a North American or European disc image or extracted Xbox maps; a PC copy is not a substitute.
- Leave enough card space. Keep about 3 GB free for the setup components identified by the repository, including temporary space for the image during setup.
- Separate installation success from online-play success. Getting the port to launch does not prove that a public server is available, that a session will be stable, or that hosting and campaign co-op have been tested on your setup.
What the 23-player result does—and does not—prove
The demonstration is notable because a modest handheld ran a native port of an original Xbox game while connected to a crowded public match. Its technical explanation is specific: an OpenCE-based ARM64 port on H700 hardware, with multiplayer provided by the OpenCE build. The developer’s report gives a real example of the setup working, rather than evidence that the device was acting as a miniature Xbox emulator.
Its scope remains one reported match on one tested handheld. The 23-player count is not a general capacity specification, and the reported 50–60 fps is not an independently reproduced benchmark. The available account does not establish typical network quality, results on other handhelds, or hands-on verification of handheld hosting and online campaign co-op. Those boundaries are why the most accurate claim is that this specific port was reported joining a 23-player public game—not that every compatible handheld can reliably run full Halo multiplayer at a guaranteed frame rate.
