If you mean that you have Dolphin functioning well on Ubuntu, I highly recommend playing Soul Calibur 2. It works flawlessly and I even paired a second set of JoyCons to my Switch for whenever I dock it at a friend's house. Soul Calibur 2/DBZ Budokai 1/2, F-Zero GX, and Medal of Honor European Assault are my go-to two-player games, and Zelda Twilight Princess, WarioWorld, Ty 3, and Scaler are my main single-player games at the moment.
Remember that some games will work better than others depending on the intensity but by adjusting the CPU you can get nearly every game working at a consistent speed. Go to configs, advanced, check the "Enable Emulated CPU Clock Override" box, and try adjusting the slider depending on how well each game works. The base setting for mine was at 80% but I found that Soul Calibur 2 and Medal of Honor work significantly better when dragged down to about 30%/35%. Other games tended to play very slowly until I returned it back to the original 80% CPU rate. Try going up and down in increments of about 5% until you find what works for each game. Generally speaking though, I would say that the 30%-85% range gives me the most consistent framerate overall.
Awesome thanks, I'll check it out!
