I would love to get some GC games on the Switch as well, unfortunately Lakka seems to be the only solution currently... Not sure I want to go there yet.

A hacker got N64 and GameCube games to run on Nintendo's Switch and posted videos of the results
On Thursday, game modder @_Mizumi showed off the N64's Pokemon Snap, the GameCube's beloved Super Smash Bros. Melee and the Game Boy Advance's Phoenix Wright: Ace Attorney running on the portable console, with mixed results.
Pokemon Snap seems to run smoothly in a silent clip. Smash Bros. has no sound and runs slowly. Phoenix Wright runs well but with no sound.
