OS wise this is ready to go, my main concern is that their emu deck project is written in a way that needs KDE to be fully functional. Hopefully this is just because is started out as a steam deck app and isn't inexperience.
The old frontends like Hyperspin and Launchbox were similar in that they were developed in such a way it really limited where those projects could go, as such the retro frontends for Linux have been pretty limited.
Be really cool to see them expand Emu deck into a standalone program, it's even cooler that we're seeing the intention of Ublue already allowing people to achieve their goals.
