I want to see if there are any wii emulators for the switch that run well so I can play games like trauma center
This. They're cheap and can play Wii/GC games natively. The emulation on N64 is great with retroarch. The official gamecube adapter let's you use real controllers and even special controllers like the bongos or DDR mats. You can use the classic NES/SNES controllers with it. Raphnet makes n64 adapters.Your best option is to buy and mod a wiiu, they are really cheap.
