Yes, some PS5 software can run on an Xbox Series X using an app called KytyPS5. It is still a work in progress, so the results depend on the game and the version of the app you use.
The developer says some games can start, show 3D graphics and play sound on Xbox. That is an exciting step, but it does not tell us whether you can play a particular game from start to finish.
Here is what the Xbox project’s own notes tell us as of October 19, 2026. We have not tested the app ourselves.
How does it work?
PS5 games need software that helps them work on different hardware. Think of KytyPS5 as an interpreter: it helps the Xbox understand what a PS5 game is asking it to do.
The Xbox version runs in Developer Mode, a separate mode for trying out software. It also has its own code for drawing graphics and reading Xbox controller inputs.
According to the app’s instructions, Xbox buttons and stick movements can stand in for some PS5 touchpad and motion controls. How well that works will depend on what a game asks you to do.
Which Xbox consoles can use it?
The developer offers an experimental version for Xbox Series X and Series S. Here is the important difference between being able to install it and knowing that a game plays well:
| Your console | What we know |
|---|---|
| Xbox Series X | The developer describes games running on this console. Check the results for the game you want. |
| Xbox Series S | The app is offered for Series S, but the tests cited here describe Series X. Results may differ. |
| Xbox One | The developer says this version does not support Xbox One. |
What has actually been shown to work?
The developer’s Xbox progress notes describe these results on Series X:
| What worked in the developer’s tests | What that tells us |
|---|---|
| Some games start and play sound. | The app can get some games running. |
| 3D graphics and videos appear. | It can display the tested scenes. |
| Controller inputs and feedback work. | Players can control games in the tests described. |
These checks do not give us a full list of games that you can finish on Xbox. For a game you care about, look for a test that shows:
- The game’s name and the Xbox model used.
- The version of KytyPS5 being tested.
- A longer stretch of play, rather than just the opening menu.
- Working sound, controls and saved progress.
Also check whether a video was recorded on Xbox or PC. The project warns that a game working on a computer may fail on Xbox. Screenshots of Astro Bot or Demon’s Souls in its desktop documentation do not, by themselves, show those games working on an Xbox.
What changed in the October 18 update?
The October 18 release notes list several improvements:
- Quicker loading for games stored in the app’s archive format.
- Memory-saving settings turned on by default.
- More controller, sound and picture settings.
- Fixes for graphics problems that previously stopped some games.
These are improvements reported by the developer. They do not give every game the same speed or reliability. Always check which version a gameplay video uses.
Why might games still run slowly or crash?
One reason is memory. A console has to share its memory between the system and the software it runs.
Microsoft’s archived guide for this type of Xbox app lists these limits for software running in the foreground:
- Apps: up to 1 GB.
- Games: up to 5 GB.
This means working memory, or RAM, rather than storage space for downloads. Microsoft says these limits do not apply when software runs through its Visual Studio testing tool.
KytyPS5 can move some data out of working memory into a file to help stay within its memory budget. That may help a game run, but it is not a promise of smooth play.
Graphics are another challenge. The Xbox version has to draw the game using a different graphics system from the PC version. Some features still need workarounds. A speed result from a powerful PC therefore tells you little about how the same game will feel on your Xbox.
What do you need to try it?
The developer’s setup instructions call for:
- A supported Xbox with Developer Mode enabled. Microsoft explains how to activate it and what account you need.
- A release from the developer. Follow the instructions for that exact version, including installing the extra files it needs.
- A computer to help with setup. The instructions use Xbox Device Portal to install the app and explain how to prepare a USB drive for game files.
- Legally obtained game files. The project does not provide games or a free PS5 game library.
Developer Mode is separate from the mode you normally use to play Xbox games. Microsoft says you need to switch back to Retail Mode to use your normal retail games and apps.
For regular Xbox downloads, our guide to installing games remotely on Series X or S explains that everyday process.
Is it worth trying?
If you enjoy testing new software, this could be an interesting project to follow. Expect to spend time setting it up and checking whether individual games work.
If you mainly want to sit down and play, look for longer Xbox tests of your chosen game first. A game reaching its opening screen is a useful step, but working saves and steady play matter much more for an evening of gaming.
Frequently asked questions
Can you play PS5 games on Xbox Series X?
The developer says some PS5 software runs through KytyPS5 in Developer Mode. You still need to check whether your chosen game works well on the version you use.
Does it work on Xbox Series S or Xbox One?
The app is offered for Series X and Series S. The tests described here are for Series X, so do not expect identical results on Series S. Xbox One is not supported.
Do you need Developer Mode?
Yes. The Xbox version uses Developer Mode. You can switch back to Retail Mode for your normal Xbox games and apps.
Can it run every PS5 game?
No. The project does not show that every PS5 game is playable on Xbox. A game working on PC does not guarantee that it works on Xbox.
Where can you download it?
Visit the developer’s GitHub releases page. The versions checked for this article are early test releases. Read the instructions attached to the version you choose.
Is this an official PlayStation feature for Xbox?
No. KytyPS5 is an independent project. Its documentation says it is not affiliated with Sony or PlayStation. Microsoft providing Developer Mode does not mean it endorses this app.
