RPCS3’s experimental Xbox port has a mixed compatibility picture: its developer’s October report calls some PS3 games playable, while others only reach gameplay or fail to boot. The reported frame rates are typical averages pooled across Xbox Series X and Series S, based on developer tests and opt-in telemetry from October 24–27, 2026, on builds 0.1.34.73–0.1.35.7.
The unofficial app runs in Xbox Developer Mode as a Universal Windows Platform (UWP) app. The upstream RPCS3 team does not support the port.
What the October compatibility report says
The project’s results distinguish games described as playable from titles that only reach gameplay. A game appearing in-game does not necessarily mean it remains playable: the developer reports freezes or crashes for several titles.
| PS3 title | Reported status and typical average | Reported limitation |
| Minecraft: PlayStation 3 Edition | Playable, 50–57 FPS | Small stutters; sessions up to 37 minutes were reported. |
| Minecraft: Story Mode | Playable, 30 FPS | The game itself caps the frame rate at 30 FPS; sessions over two hours were reported. |
| Grand Theft Auto V | In-game, about 22 FPS | Limited by emulated SPUs, with drops while new SPU code compiles. |
| Portal 2 | Playable, about 26 FPS | Short stutters; limited by the emulated PPU main thread. |
| LittleBigPlanet | In-game, about 20 FPS | Freezes and crashes after a few minutes. |
| WipEout HD Fury | In-game, about 45 FPS | Stutters during shader compilation. |
| X-Men Origins: Wolverine | Playable, 22–24 FPS | May crash after about 30 minutes. |
| FIFA Street | Does not boot | Exits immediately. |
The numbers in the table are the developer’s typical averages pooled across Series X and Series S. The report does not give separate figures for each console, so it does not answer whether the Series S runs these games differently from the Series X. The project’s October 29 repository update merged build 0.1.35.11, later than the builds covered by the October 24–27 performance report.
First launches can take several minutes while the emulator compiles code and shaders; later launches can use cached data. The developer also says a recurring “Out of host memory” crash can happen when the Xbox graphics driver rejects a frame, rather than because the console has actually run out of memory.
Setup choices that affect the port
The project’s documented setup requires an Xbox Series X or Series S in Developer Mode, a developer account, a PC on the same network, Device Portal enabled in Dev Home, external USB storage, and the user’s own PS3 firmware and games. The project does not provide commercial games. Its README lists firmware version 4.93 as tested.
The developer says the default app type allocates 1 GB of memory to the app. In Dev Home, setting App type to Game allocates 5 GB instead. The README’s installation instructions use the RPCS3 .appx package and the Microsoft.UI.Xaml.2.8.appx dependency, installed through Device Portal. The project repository also documents loading firmware and game files from external storage.
The Xbox controller’s A, B, X and Y buttons map to PS3 Cross, Circle, Square and Triangle. Menu and View map to Start and Select; pressing View and Menu together opens the PS button menu. The app menu uses the directional pad or left stick to navigate, A to select, B to go back, LB and RB to switch tabs, and Y to rescan the drive.
What the developer says optional telemetry includes
The developer says the app sends telemetry only when a user opts in. The listed information includes emulator logs, app and build details, console model, firmware and settings, the game title and run time, and a random anonymous ID. The developer says the logs exclude account identifiers, IP and MAC addresses, location, and game-library lists.
