Quick TakeArticle at a glance
- An experimental emulator called PS5X is now running real PS5 games on Xbox Series X, built by developer Devran Cosmo Uenal on top of the open-source KytyPS5 project.
- An October 18, 2026 build fixed roughly 15 additional rendering cases, letting more titles boot.
- It runs inside Microsoft's official Developer Mode under a hard 5GB memory limit, so this is not something a normal Xbox owner can use yet.
PlayStation 5 games are running on Xbox Series X for the first time, through an experimental, unofficial emulator called PS5X that translates PS5 software to run on Microsoft’s hardware. It is not an officially sanctioned feature from either Sony or Microsoft, and it currently only works inside Xbox’s Developer Mode under a tight memory cap.
What Is the PS5X Emulator?
PS5X is a community project from developer Devran Cosmo Uenal that ports the open-source KytyPS5 emulator to run on Xbox Series X|S hardware instead of a Windows PC. The challenge is that KytyPS5 was built around Vulkan, the graphics API PS5 games use, while Xbox consoles run on Microsoft’s own DirectX 12 — so the PS5X build has to translate PS5 graphics calls into DirectX 12 on the fly, rather than simply running the same code.
Which PS5 Games Actually Run on Xbox Right Now?
Uenal first showed the project running Quake II, GEX Trilogy, Hellboy: Web of Wyrd, and Marvel Cosmic Invasion, with Xbox controller input working and audio present in several tests. Quake II runs at roughly 25 to 45 frames per second with noticeable input latency between a button press and the result on screen — this is an early research build, not a finished product.
It’s worth separating two different stories that have circulated together: PS5X genuinely emulates small, lightweight PS5 titles like Quake II. Separately, bigger PlayStation games including The Last of Us Part 1 and Marvel’s Spider-Man Remastered have also shown up running on Xbox Series X at 50-60 fps — but those are their existing PC ports running through Universal Windows Platform compatibility layers, not PS5X emulating the PS5 disc versions. Reports that conflate the two overstate what the emulator itself can currently do.
What Changed in the October 18 Build
The build released October 18, 2026 updated PS5X’s Direct3D 12 renderer to correctly handle about 15 additional cases that previously crashed games outright, including depth-to-color copies, 64-bit atomic operations, certain texture formats, and other rendering operations. Uenal has said AI-assisted tools are being used to help convert code during development, on top of graphics fixes, faster loading, and memory-handling improvements aimed at getting more titles to boot.
Why Can’t I Just Play PS5 Games on My Xbox Today?
PS5X currently only runs inside Microsoft’s official Xbox Developer Mode, a sandboxed environment Microsoft provides for homebrew and indie testing — not the regular Xbox dashboard every console ships with. Developer Mode caps any app at 5GB of memory, which is a hard ceiling compared to what a normal Xbox game can use, and Uenal himself describes PS5X as an early-stage research project with limited compatibility rather than something ready for general use.
| PS5X on Xbox Series X | Native PS5 | |
|---|---|---|
| Status | Experimental, Developer Mode only | Official, full retail support |
| Memory available | Capped at 5GB (Developer Mode limit) | 16GB unified GDDR6 |
| Confirmed working titles | Quake II, GEX Trilogy, Hellboy: Web of Wyrd, Marvel Cosmic Invasion | Full PS5 library |
| Access | Requires enabling Xbox Developer Mode and building from source | Standard console use |
Frequently Asked Questions
Can an Xbox Series X run PS5 games?
Experimentally, yes, through PS5X, an unofficial fan-made emulator — but only inside Xbox’s Developer Mode, with a handful of lightweight titles confirmed working and a hard 5GB memory limit.
Who made the PS5X emulator?
Developer Devran Cosmo Uenal built PS5X on top of the open-source KytyPS5 emulator project, translating its Vulkan-based PS5 graphics calls to DirectX 12 for Xbox hardware.
What games work with PS5X?
Confirmed working titles include Quake II, GEX Trilogy, Hellboy: Web of Wyrd, and Marvel Cosmic Invasion, with varying levels of controller and audio support.
Are The Last of Us and Spider-Man Remastered really running on Xbox through PS5X?
No. Those are their existing PC ports running through Universal Windows Platform compatibility layers, not PS5X itself emulating the PS5 disc versions of those games.
Is the PS5X emulator something I can download and use?
It’s available through the KytyPS5 GitHub releases page, but it requires enabling Xbox Developer Mode and is described by its own developer as an early-stage, limited-compatibility research project.
