Motionless controllers and games with motion

[Xirix]

I'm curious about trying to play New Super Mario Bros Wii with a friend using netplay, he does not have a Wii controller. Assuming you can configure Dolphin to use any controller (in this case it'll be an Xbox 360 controller), what happens when games use motion as a control?

For instance in said game, waggling is used to both spin jump and to move the bubble you respawn in if one of you dies, is it possible to just make this a button you need to tap repeatedly?

You can actually map a button on the controller for that function specifically. I mapped mine to the B button for that and SMG.
