Correct. Unfortunately, it’s something that each desktop environment or window manager has to implement themselves. But all the button is doing is moving some config files around, so you can probably do some digging to figure out what it’s copying to where.
I’m one of those weirdos who actually dumps all my own games with my own modded launch Switch mainly for preservation purposes.
But then TotK came out and performed so poorly on the console itself, I exported my save to play on PC and Steam Deck. Every part of my Switch emulation journey has been legal and by-the-book: dumped my own firmware, my own keys, and my own games.
Fuck Nintendo for bullying these developers.
