Developer runs PS5 games on Xbox Series X via PS5X emulator

Developer Devran Cosmo Uenal ported the open-source PS5 emulator KytyPS5 to Xbox Series X as PS5X and got four games, including Quake II, running. It only works in Developer Mode with a 5GB memory cap, and there is no public build yet.

• PS5X runs GEX Trilogy, Hellboy: Web of Wyrd, Marvel Cosmic Invasion and Quake II
• Developer Mode caps games at 5GB of memory versus 13.5GB in retail mode
• Quake II runs at roughly 25 to 45 fps with Xbox controller input
• No public download exists, and KytyPS5 needs Vulkan 1.3, which Developer Mode lacks
