per the github repo:

What devices are supported?

    Steam Deck
    Linux (check Wi-Fi hardware compatibility)
    Nintendo Switch (requires Broadcom firmware patch or external Wi-Fi adapter)
    Android (currently frontend only)
    Windows (currently frontend only)
    Raspberry Pi (requires external Wi-Fi adapter)
    iOS - Coming soon

You can. It works really well, except for not supporting the Wii U power button and not yet allowing button reconfig. The latter is annoying because you are using Xbox bindings on Nintendo.
