Developers have introduced ProsperoEden, an early alpha port of the Eden Switch emulator that allows Nintendo Switch games to run on the PlayStation 5 with homebrew mode enabled.
The software currently supports video output, audio playback, full controller input, and a functioning save system.
Benchmark tests show varying performance across titles.
Hollow Knight runs stably, Metroid Dread reaches 59 to 60 FPS on the title screen, and Super Mario 3D World achieves between 35 and 53 FPS during its animated introduction.
ProsperoEden includes features such as toggling between handheld and desktop modes for each game, a performance overlay, and hotkeys for returning to the menu.
To use the emulator, a PlayStation 5 console with homebrew enabled is required, along with Switch key dumps, system firmware, and game files provided by users.
The developers plan to release the project's source code later, though compatibility remains limited due to the project's early development stage.
The emergence of ProsperoEden highlights the gradual evolution of the PlayStation 5 into a platform supporting third-party applications and emulators.
