Yeah. I'm no programmer, but I think some arcade-drive code is included in the default code, so you can probably look there.

From what I remember our programmers saying, the up/down of a joystick (Z), and the left/right of a joystick (X) control whether you turn left or right, or go forward or backwards. Or a mixmatch of any of the options (ie. forward and right).

Hope this helps!
