This is a landing page for the two versions of Cemu bundled with EmuDeck, proton and native (AppImage). EmuDeck includes the native build of Cemu as an optional install. If you choose to install the native version of Cemu, both versions will remain installed to provide the user choice and to allow for the native version to mature and fix any lingering issues.

To try out the native version of Cemu, open the EmuDeck application, click the Manage Emulators button, click Cemu, and click install Cemu AppImage.

What is the difference between the proton and the native version?

Back to the Top

Up until the end of 2022, Cemu only provided a Windows version. EmuDeck bundled this windows version and created a script to run it through Proton. At the end of 2022, Cemu released a native Linux version as an AppImage. The AppImage released in a beta state and still had issues, both with general emulation and game compatibility.

Throughout 2023, Cemu released frequent updates to improve the performance and compatibility of the native version. However, as of May 2023, there are still lingering issues and some games do not run well. These games do run well on the Windows counterpart of Cemu.

EmuDeck only started to bundle the native version of Cemu with EmuDeck 2.1, released in April, 2023. Many EmuDeck users still use the Windows version of Cemu and have not fully migrated over to the native version yet.

The foreseeable future should see improvements and eventual parity with native Cemu and a full migration in EmuDeck from the Windows version.
