The ProsperoEden on PS5 received a new public version on September 25, 2026 and is already able to run Nintendo Switch games directly as homebrew on Sony's console. The project is an unofficial port of the Eden emulator and is in the alpha stage, but already offers video, audio, controls, and saves in compatible titles.

The current version, identified as v1.000.010, also brought changes to the OpenGL renderer, performance improvements, fixes to game loading, and an individual option to toggle between the Nintendo Switch's handheld and docked modes.

The project appeared publicly a few days earlier and still has a small compatibility base. Therefore, the current results do not mean that the PS5 can already run the entire Switch library satisfactorily.

ProsperoEden on PS5 uses Eden as its base

The official ProsperoEden repository defines the project as an unofficial port of Eden for PlayStation 5 homebrew. The emulation core still belongs to Eden and its contributors, while the new project adapts that code to the Sony console environment.

This distinction is important. ProsperoEden is not a new Nintendo Switch emulator created from scratch. It reuses the Eden core and adds the necessary infrastructure to run it as a native homebrew application on the PS5.

The graphics layer utilizes the ps5-openglproject. According to the documentation, this implementation provides the native OpenGL layer used by Eden's graphics backend inside the console.

The approach differs from running an emulator inside a Linux installation on the PS5. In this case, the program uses a native application framework built on top of the PS5 Native App Boilerplate, which also serves as a foundation for other homebrew projects.

Version v1.000.010 improves renderer and loading

Version v1.000.010 updates OpenGL renderer operations and render target compatibility. The team also mentions changes related to multisample operations and graphical performance.

Additionally, game loading and closing received fixes. The changelog specifically highlights an issue during the startup of Metroid Dread and a crash when returning from Super Mario 3D World to the launcher.

Another new feature allows individually selecting the mode Handheld or Docked in each game's settings. The chosen option takes effect the next time that title is launched.

The port also features support for DualSense, audio, saves, and a performance HUD. The touchpad combined with R1 toggles the performance overlay, while touchpad + L1 exits the current game and returns to the ROM menu.

ProsperoEden on PS5 still exhibits erratic performance

The developers themselves classify the ProsperoEden on PS5 as an initial alpha version. Therefore, compatibility, stability, and performance still vary quite a bit from one game to another.

In development tests published in the repository, Horizon Chase Turbo reached approximately 33 to 36 FPS in its menu. Super Mario 3D World showed between 35 and 53 FPS on the animated title screen, while Metroid Dread reached 59–60 FPS on the title and file selection screen.

Mario vs. Donkey Kong, meanwhile, hit 30 FPS on the title screen.

These numbers need context. The developer himself clarifies that these are menu and title screen checkpoints obtained during development. Therefore, they do not represent full gameplay benchmarks nor do they guarantee the same performance in the version distributed to the public.

Initial community reports also show great variation. In a post made by the developer on Reddit on September 26, users began testing different games and firmware versions. Some reported it working in certain titles, while others encountered black screens, boot errors, or instability.

Thus, these reports should be treated as individual tests and not as an official compatibility matrix.

Demanding games remain a challenge

The project itself warns that more demanding games are still far from the ideal stage. Pokémon Legends: Z-A, for instance, remains very slow and may crash when exiting the game.

Mario Kart 8 Deluxe also received improvements, but still does not maintain 60 FPS during gameplay in docked mode, according to the current documentation.

On the other hand, the README confirms Hollow Knight working with video, audio, controller, and save system. This is one of the cases used by the developer to demonstrate that the core can already run commercial software within the PS5 homebrew environment.

The scenario resembles the early stage of other emulation projects that rapidly expanded their compatibility after the first public builds. At Allves Games, we also follow the progress of KytyPS5 in PlayStation 5 emulation and native execution projects like the GTA Liberty City Stories PC port.

Full source code of the port will still be published

Despite using open-source components, the specific port code was not yet publicly available during this check. The developer states that they intend to publish it after completing performance optimizations, UI adjustments, and repository preparation.

Meanwhile, the ps5-opengl, used as a graphics layer, is publicly available.

This also reinforces the initial nature of the project. The ProsperoEden repository was created in September 2026 and continues to receive changes as the first users expand compatibility testing.

ProsperoEden requires files obtained by the user themselves

The emulator package does not include games, firmware, Nintendo Switch keys, or other protected console data. The documentation requires the user to provide their own legally obtained files.

The ProsperoEden on PS5 it also requires a console capable of running homebrew. Therefore, it is not an application officially available through the PlayStation Store nor a functionality supported by Sony, Nintendo, or the official Eden team.

Even with these limitations, v1.000.010 establishes an interesting technical milestone: a modern Nintendo Switch emulation core is already able to run commercial software directly within the PlayStation 5 homebrew environment. The next step will be to observe how far the renderer, CPU performance, and compatibility can advance as the port code matures.
