Devran Cosmo Uenal’s PS5 emulation project, PS5X, is now running on Xbox Series X. Early tests have already put Quake II on the machine with controller and audio support, which pushes the work beyond a PC-only experiment and into Microsoft hardware.
PS5X on Xbox Series X
PS5X is built on KytyPS5, and it adapts that emulator’s Vulkan-based framework to the Xbox Series X’s DirectX 12 environment. That is the practical hurdle here: graphics calls written for one rendering path have to be translated into another before the game can draw anything useful.
Uenal described the effort with the post, “Quer ver uma parada INSANA? XBOX SERIES X EMULANDO PS5!”
Quake II and 5GB RAM
The current demonstration is limited to Quake II, and the project is still described as experimental and far from full PS5 emulation. The source also says the Xbox Series X has a 5GB RAM limit, and that the FPS caps out at 25-40 because of that limit.
That ceiling is the part readers should watch. A PS5 emulator can show a booting game and still fall apart once memory pressure, driver translation, and game logic all pile up, so a stable demo is not the same thing as support for a modern PS5 library.
PS5 emulation on PC
The broader context is a steady climb from older systems to newer ones. PPSSPP let players run PSP games such as God of War: Chains of Olympus and Grand Theft Auto Vice City Stories on Android devices or PC, and RPCS3 brought some PlayStation 3 games to PC.
More recently, KytyPS5 booted the PS5 version of GTA 5 and ran its opening prologue at 40-60 FPS on high-end hardware, but that build remained extremely unstable and crashed within minutes. It also drew attention because KytyPS5 was reported to run Astro Bot on PC at a 30fps performance level, which makes PS5X’s move to Xbox Series X a real technical step, not a finished product.
The unresolved question is whether PS5X can move beyond Quake II and into actual PS5 games without running into the same instability and memory limits that still define this project.
