So here is the pack :

I added support for xbox 360 controller. To use this pack, extract it, copy the settings.bin file located in the cemu folder into your own cemu folder (backup the old one if you want) and open wiimote.pie or xbox360.pie with PIEFree. Then, click on start and wait...
If you are using a wiimote, make sure you have bluetooth on your computer and click on 1 and 2 until it displays only one LED.
With the xbox 360 script, I inverted the A/B X/Y buttons, to do like on the wii u controller. And to display the gamepad, click on the right shoulder. The right stick can be used as a mouse and a click on it is like a mouse left click.
Enjoy !
Edit: I made a mistake, download this
