Mapping Nunchuk shakes to a gamepad button (for Okami)

[notpigeon]

I've been trying to find a workable control setup for Okami and the one last thing I haven't found a good way to map is the dodge move. As far as I can tell dodging only responds to the "shake" command in the Nunchuck settings, and because of the way the shake bindings work I can't find a way to reliably control where Amaterasu dodges when I press R2. It seems like my options are either to bind the button to just X, Y, or Z, which means I can only dodge in one direction (left with X and forward with Y or Z), or to bind some combination of X, Y, and Z together, which causes Amaterasu to dash off in random directions with no apparent rhyme or reason. Is there a better way to bind this that I'm not seeing, or am I just going to have to deal with not controlling where I dodge?
