I'm using this controller fairly successfully with MAME OSX. However, my one complaint is I am unable to calibrate the right joystick axis (sometimes referred to as the z-axis, but MAME tends to call it "axis 4")
The problem is that when the stick is in the neutral position, MAME sees it as being pushed up, or away from me. In order to get MAME to sense that the stick is in the neutral position, I actually have to hold the stick slightly downward.
Is there a utility anyone knows of that would "re-calibrate" the joystick so that MAME sees the actual position?
