im not sure if thats even possible.

Replying to someone: Yes, it is impossible, as the 3ds and Wii U CPU's are diffrent or somthing lol

The 3DS emulator, citra, is not like most emulators with a "dymanic recompiler", meaning it's not very efficient. Someone will need to make a entirely new way of emulating 3DS for it to even run remotely smoothly on Wii U, kinda like DS Vita for PS Vita.

Or it's impossible, if I ever get linux on my Wii U i'll see if citra even runs at all
