It’s not a cheap solution, but I’ve got Lakka going on my Switch and it works great. Still has trouble with Dolphin Gamecube emulation (and Wii games just don’t work) but PSP, N64, and SNES work perfectly.
I am totally waiting for Lakka to work on the Nintendo Switch Lite. If we can make it work up to the Dreamcast. That would totally be dream come true.
Having system like Gamecube running nicely on the Switch might be asking for too much. Unless, Nintendo figure out how to.
