Experimental PS5 Emulator Is Already Running on Xbox Series X

An experimental PlayStation 5 emulator is now running on the Xbox Series X, creating the unusual situation of Sony’s current-generation software being emulated on Microsoft’s console.

The project is called PS5X and is being developed by Devran Cosmo Uenal. Rather than being built entirely from scratch, PS5X is an experimental Xbox port of KytyPS5, an open-source PS5 emulator that has already been under development on PC.

Getting PS5 Emulation Working on Xbox

One of the biggest challenges is graphics.

KytyPS5 uses Vulkan for rendering, but the Xbox environment being used for PS5X does not support Vulkan. That means the graphics side of the emulator has to be adapted to work with DirectX 12 instead.

This isn’t simply a matter of changing a setting. Rendering instructions and other parts of the graphics implementation need to be translated or rewritten so they can work correctly within the Xbox environment.

Despite the technical challenge, the project is already producing some interesting results.

Early demonstrations have shown Quake II running on an Xbox Series X, with both controller input and audio support working. Reports also indicate that the emulator is being tested through the Xbox’s Developer Mode.

AI Is Helping With Development

Another interesting part of the project is the use of AI-assisted development.

Uenal has said AI tools are being used to help with parts of the development and code-conversion process. This could be particularly useful when adapting components originally designed around Vulkan to Microsoft’s DirectX environment.

However, the exact extent of the AI-generated or AI-assisted code hasn’t been clearly documented, so it would be premature to say how much of PS5X’s progress is directly attributable to AI.

Don’t Expect Xbox to Replace a PS5 Yet

As impressive as the demonstration sounds, PS5X is nowhere near being a complete PS5 emulator.

Getting Quake II and a handful of other pieces of software running doesn’t mean an Xbox Series X can suddenly play the entire PS5 library. Compatibility remains extremely limited, and issues involving graphics, performance, stability and individual game behavior still have to be addressed.

Even KytyPS5 itself remains experimental, so porting it to another console introduces another layer of technical challenges.

For now, PS5X is better viewed as a research project and technical proof of concept rather than something Xbox owners can use as a practical replacement for a PlayStation 5.

Still, seeing PS5 software running through emulation on an Xbox Series X — complete with working controls and audio — makes PS5X a fascinating project to watch as development continues.
