This is not public yet, but fail0verflow have Linux running on Switch, and since HW acceleration also works, nothing stopped them from trying Dolphin on it.
And, well, for unoptimized open source drivers it runs pretty good.
He also showed Animal Crossing (CGN) and Spyro 1 running at (or near) full speed in Dolphin/PCSXR.
(Also, I'm not sure which Distro that is, I think Debian with some KDE GUI)
