Hi, to play it on your Wii U, you need to have Tiramisu/Aroma installed, and don't be scared of the game crashing in Cemu, Cemu, is an experimental emulator, and ports are not optimized/made for it, we already know it crash on Cemu, but in Wii U it doesn't crash, and is not going to break your Wii U.
