PS5 emulation arrives on Steam Deck, Astro Playroom showcased running at 0.6 FPS — milestone SharpEmu development shows promise, despite unplayable performance
The PlayStation 5 emulation scene has been a wonder to witness, with rapid progress matching the community’s ambition. The latest development on this frontier is SharpEmu, an open-source PS5 emulator, successfully running on the Steam Deck with Astro’s Playroom even booting to show the PlayStation Studios loading screen. The framerate doesn’t go past 1 FPS, but the fact that it’s even running is very impressive.

We scoured the internet for more information on this but couldn’t find anything. This seems to be the first and only case of someone getting a PS5 game to load on a Steam Deck without streaming involved. The video above shows the Steam Deck in its desktop mode inside SteamOS, which is based on Linux. Performance fluctuates between 0.5 FPS and 1 FPS according to the overlay in the corner, and the audio is just as choppy.
SharpEmu can smoothly run lightweight 2D titles like Dead Cells and Dreaming Sarah on more capable hardware, but the team’s focus is not on compatibility. KytyPS5 is far more advanced in terms of the games people have been able to boot on it, including 3D titles like Demon’s Souls. However, Kyty is limited to Windows while SharpEmu has native support for Linux and Mac, and there’s even an unofficial Android fork.

We tried this version on a OnePlus 12 and were able to get Dreaming Sarah to show an initial splash screen with the developer’s logo. After that, though, the screen turns black, and nothing happens, despite the FPS counter constantly hovering around 60 FPS. A few questionably optimistic users on Reddit have even suggested running SharpEmu on Android through Winlator, so that GTA VI can be played on Android once it launches.

Just like the Steam Deck, even the fact that the game launches on Android is a mighty feat and a testament to the sheer ambition of this community. SharpEmu is only meant for x86 devices; it runs on Apple Silicon Macs through the Rosetta 2 translation layer, and on Windows-on-Arm devices through Microsoft‘s Prism translation layer. But since it’s written in C# from scratch, evidently, the code can be recompiled for Android.
With the ongoing component crisis making even consoles more expensive to purchase, and the death of physical media right around the corner, emulation is once again being touted as a cornerstone of preservation. With a roadmap to playing GTA VI on PC without waiting a few years for a port no doubt in the back of everyone’s minds.
