An experimental Nintendo Switch emulator called ProsperoEden is now running natively on jailbroken PlayStation 5 consoles, achieving playable performance in commercial games such as Cuphead and Metroid Dread while utilizing an OpenGL backend on firmware 6.02.
The boundary between console ecosystems continues to blur as developers push hardware in unintended directions. An experimental Nintendo Switch emulator called ProsperoEden has successfully booted and run Switch games natively on PlayStation 5 consoles, according to project disclosures and compatibility notes.
ProsperoEden Architecture and System Requirements
The project originates from Eden, an open-source Switch emulator derived from the wider Yuzu codebase. While the base Eden software supports Windows, Linux, macOS, and Android platforms, the ProsperoEden port specifically adapts the architecture for Sony’s console hardware. The emulator runs through an OpenGL backend, as no Vulkan renderer has been implemented for the port yet.
Testing for the port has primarily taken place on PS5 firmware 6.02, though users have also reported functionality with earlier builds on firmware 12.70. The v1.000.010 software iteration introduced targeted OpenGL refinements covering multisample operations, render-target compatibility, shader handling, and depth copies, alongside general improvements to game loading and shutdown routines.
Compatibility and In-Game Performance
Although the project remains in an early alpha release stage, several commercial titles already reach playable states on the Sony hardware. Performance and stability vary significantly across different titles, with current builds largely limited to 2D and platform games rather than massive 3D AAA releases.
- Cuphead: Reaches a smooth 60 frames per second.
- Metroid Dread: Operates at approximately 40 frames per second.
- Super Mario 3D World: Listed as playable in tested sections.
- Mario Kart 8 Deluxe: Reaches actual gameplay, averaging roughly 39.5 FPS, which sits below its original 60 FPS target.
- Other tested titles: Hollow Knight, Horizon Chase Turbo, Mario vs. Donkey Kong, and Pokémon Legends Z-A have also booted into ingame states.
Players can toggle individual software between handheld and docked modes, with settings applied upon the next launch. The software also incorporates DualSense controller support, saves, and a built-in performance overlay. Users can bring up the performance HUD by pressing the touchpad plus R1, or close the running game and return to the ROM menu using the touchpad plus L1 shortcut combination.
The Broader Console Emulation Landscape
The release arrives at a time when hardware emulation discourse is moving in multiple directions simultaneously. While developers have made significant strides porting PlayStation 5 titles to personal computers and experimental tools have bridged Sony hardware to Xbox Series X|S, ProsperoEden reverses the flow by bringing Nintendo titles directly onto Sony’s console.
Nintendo maintains a famously aggressive legal stance against emulation projects, previously shuttering mainstream software like Yuzu.
