PS5 emulation is now running on Xbox Series X.
The KytyPS5 emulator has been ported to Xbox Series X as a UWP app through Developer Mode. Some PS5 games are already booting with sound and controller support.
The Xbox version uses a Direct3D 12 renderer and Mesa’s shader translation to make the PS5 software work on Xbox hardware.
Performance is still rough: Astro Bot is around 10 FPS on Xbox right now, so this is definitely not replacing a PS5 yet.
