An experimental PlayStation 5 (PS5) emulator called PS5X has been successfully run on an Xbox Series X, according to a developer named Devran Cosmo Uenal. This emulator is based on KytyPS5, an open-source project that aims to emulate the PS5 on personal computers. Unlike standard applications found in the Microsoft Store, PS5X is run through the Xbox Series X's developer mode, which allows for testing and running experimental software not available to the general public. This achievement showcases the potential for cross-platform gaming, even if it's still in the early stages of development. Devran has demonstrated that several PS5 games—including GEX Trilogy, Hellboy: Web of Wyrd, Marvel Cosmic Invasion, and Quake II—can be run on the Xbox Series X through the emulator. These titles are also available on other platforms, and their PS5 versions are being executed through emulation. The Xbox Series X recognizes the controller for these games, and sound works in some cases. Quake II, in particular, offers insight into the current state of the project. While the game generally runs between 25 and 45 frames per second, it occasionally dips below 20 FPS, and there is noticeable input lag, indicating that performance is still far from optimal. One of the main technical challenges the developer faces is adapting the graphical rendering from Vulkan, a graphics API used by KytyPS5 on PC, to DirectX, which is supported by the Xbox. The Xbox does not natively support Vulkan, making this adaptation essential for the emulator to function on the console. On PC, KytyPS5 has made progress, with games like GTA V now reaching their main menus and other titles beginning to display gameplay. However, full compatibility with all PS5 games is still far from being achieved. PS5X remains primarily a research project with a limited list of compatible games and significant work remaining. While this achievement demonstrates the technical feasibility of running PS5 games on an Xbox Series X, major PlayStation exclusives are still far from being fully compatible. The project highlights the ongoing efforts in the emulation community to push the boundaries of cross-platform gaming, even if practical, widely available solutions are still years away.
