I use Yuzu.

its pretty good, depends on the game of course.

I recently loaded Fire Emblem Engage, super mario oddosy, donkey kong tropical freeze, and both zelda BOTW and TOTK. I was running them on my steam deck so performance was so-so, some games better than others, all of them definitely playable though (except super mario sunshine, but that was one I tried probably almost a year ago, yuzu is better now)

emulation still proves to be the best way to play.
