Flatpak for Cemu

Cemu is a Nintendo Wii U emulator. For more information, please visit the project website or view the source code.

Transfarring AppImage user data to flatpak

If you've been using the AppImage you can move your saves and settings to the flatpak sandbox with:

mv ~/.local/share/Cemu ~/.var/app/info.cemu.Cemu/data/Cemu

Shader cache with:

mv ~/.cache/Cemu ~/.var/app/info.cemu.Cemu/cache/Cemu

Setting and controller configs with:

mv ~/.config/Cemu ~/.var/app/info.cemu.Cemu/config/Cemu

Give Cemu access to Wiimotes

Create a udev rules file at /etc/udev/rules.d/50-cemu-wiimote.rules containing the following:

KERNEL=="hidraw*", KERNELS=="*057E:0306*", TAG+="uaccess"

Then load the new rule by running

sudo udevadm control --reload-rules

Disconnect and reconnect the Wiimote then restart Cemu. You should not be able to add the Wiimote as an input:

Filesystem write permissions

In order to convert files to wua you can run Cemu without filesystem sandboxing from the terminal via:

flathub run --filesystem=host info.cemu.Cemu

This can be done permanently with flatseal or with:

flatpak override --user --filesystem=host info.cemu.Cemu

More udev rules

Create a udev rules file at /etc/udev/rules.d/50-cemu.rules containing the following:

# Bluetooth Wiimote
KERNEL=="hidraw*", KERNELS=="*057E:0306*", TAG+="uaccess"

# PS4 LEGO Toypad
SUBSYSTEM=="usb", ATTRS{idVendor}=="0e6f", ATTRS{idProduct}=="0241", MODE="0666", TAG+="uaccess"

Then load the new rule by running

sudo udevadm control --reload-rules

Disconnect and reconect the device then restart Cemu.
