A project named ProsperoEden now allows Nintendo Switch games to be played on jailbroken PlayStation 5 consoles. This emulator adapts the open-source Eden Nintendo Switch emulator, which is already available for Windows, macOS, and Linux, to function on Sony's latest console. The project is currently in an early alpha stage.
Testing indicates a range of compatibility for Switch titles. Games like Cuphead and Metroid Dread reportedly run at 40 FPS or higher, with others such as Hollow Knight and Mario Kart 8 Deluxe showing similar results. However, titles like The Legend of Zelda: Breath of the Wild are deemed "unplayable," and Animal Crossing: New Horizons experiences "major issues" with frame rates around 15 FPS.
The inconsistent performance is partly attributed to the emulator's reliance on OpenGL, as a Vulkan renderer is not yet available. PS5 firmware versions also play a role; most testing occurred on firmware 6.02, though some ProsperoEden builds have worked on version 12.70. This suggests that user experience may differ based on their console's setup.
ProsperoEden is under active development, with recent updates aiming to improve compatibility and performance. The latest v1.000.010 release includes fixes for Metroid Dread and Super Mario 3D World, along with enhancements to OpenGL rendering, multisample operations, render-target compatibility, shader lifetime handling, and depth copies. The emulator supports DualSense controllers and includes game saving functionality.
