Here is the list of button values:

Button Values:
Wiimote D-Pad:
Left - 1
Right - 2
Down - 4
Up - 8

Wiimote:
Plus - 10
Minus - 1000
A - 800
B - 400
1 - 200
2 - 100
Home - 8000
Numchuk:
Z - 2000
C - 4000

So lets say for example you wanted to make a button activator that triggered on Z+Up for emotion to go forward and Z+Down to go back. You would simply add all the button numbers together = 2008 for Z+Up and = 2004 for Z+Down.

Now the code will look like (hopefully it works):
