1) Download the latest version of CEMU from here. It works only with 64bit Windows.
2) Open up your keys.txt. You gotta remove “541b9889519b27d363cd21604b97c67a # example key (can be deleted)” and replace with the Wii U Common Key. You can find it here.
3) Next you have to find and paste the game key of your game, one key per line and it should look something like this:
