Emudeck is the best and easiest way to get started with emulation on the steam deck. Its super user friendly and easy to install. Check it out here...

Switch games run impressively well on the steamdeck. I've been playing mario wonder and after a minute or so of stutters, it runs at full 60fps the rest of the time. Gotta love the steam deck.
