Install DrNokSnes and wiicontrol.

Edit /usr/bin/wiicontrol to match this configuration (dont copy/paste, on python indentation level of your statements is significant):

mapping={
‘U’: [“a a”],
‘D’: [“a d”],
‘L’: [“a s”],
‘R’: [“a w”],
‘A’: [“a z”],
‘+’: [“a x”],
‘-‘: [“a c”],
‘1’: [“a v”],
‘2’: [“a b”],
‘H’: [“a n”],
‘GU’: [“a u”],
‘GD’: [“a i”],
‘GL’: [“a o”],
‘GR’: [“a p”],
‘Z’: [“a k”],
‘C’: [“a l”]
}

Start Bluetooth (or wiicontrol crashes).
Start wiicontrol (my wiicontrol freeze and I cant select key setup but it still works).
Setup wiimote (press 1+2).
Start DrNokSnes and tap un titlebar to configure keyboard.

Enjoy!
