Developer Devran Cosmo Uenal showcased a PlayStation 5 emulator, PS5X, running on an Xbox Series X. In a YouTube video, Uenal successfully booted and played the PS5 version of Quake II using an Xbox controller. He has also managed to get three other PS5 games working through this emulator.
The primary constraint for PS5X is its reliance on the Xbox Series X's official Developer Mode. Microsoft's documentation for Developer Mode caps game memory usage at 5GB. This limitation effectively prevents the majority of current-generation PS5 titles from being playable on the Xbox via PS5X. There is currently no public release or download available for the emulator.
Both the PlayStation 5 and Xbox Series X utilize similar AMD hardware, including Zen 2 CPU cores, RDNA 2 graphics, and 16GB of GDDR6 memory, with PS5 games compiled for x86-64 architecture. The KytyPS5 emulator, which PS5X is based on, acts as a compatibility layer, translating PS5 game requests for the host CPU. KytyPS5 translates PS5 graphics commands and recompiles shaders for Vulkan. However, Xbox Developer Mode only supports DirectX 11 and 12, requiring PS5X to translate Vulkan commands to DirectX, a process Uenal stated involved AI.
Uenal describes PS5X as a 'research project' focused on running PS5 homebrew and game backups within Developer Mode. He asserts that PS5X does not include any PS5 firmware or decryption keys. The KytyPS5 documentation advises users to only use legally obtained game files, a practice that aims to avoid legal issues similar to those faced by the Nintendo Switch emulator Yuzu.

Developer Devran Cosmo Uenal demonstrated running PlayStation 5 games, including Quake II, on an Xbox Series X using PS5X, his port of the KytyPS5 emulator. This functionality is currently restricted to Xbox Developer Mode, which imposes a 5GB memory limit, preventing most current-gen PS5 games from running.
