Cemu

I'd like to play games like Pikmin 3 which is best experienced using the Wiimote as a pointing device.
The wiimote emulation does support mapping the buttons, but pointing with IR is not mappable.
I'd like to be able to user my mouse pointer to control the Wiimote pointer.
This might conflict with the touch controls for the WiiU tablet, but when using a separate window for it, or when it is not connected it should not be an issue.

Dolphin have solved this quite well, and borrowing the code shouldn't be easy.
