Ok, listen
This is all very simple
Delete all the stuff you downloaded
Download Wii U USB Helper MOD (You NEED this version)
After that, install it, input the title keys site (we cannot tell you which site it is, just google it) and download a game.
After the download is finished click where it says "prepare game for emulation" (MAKE SURE TO ALSO HAVE ALL UPDATES FOR THE GAME). THIS IS IMPORTANT because many games will not work if you are not using the latest update.
Then go to the DATA folder and navigate to where your "CEMU READY" game is and move it to... whatever folder you are placing your games on.
And with that you are done.
