I figured as much. People are always getting yelled at about not using the "Search" function, so I thought I'd attempt some diligence!
Anyway, more specifically, the X and Y axises are all f*cked up. For example, when Bonk is standing still, he quickly rotates from facing right to left, but never moves. If I press in one direction, it's as though he's fighting to move the opposite direction.
Like I said, the controller works fine with other emulators and with games on Steam, and it always worked well with my PC version of Magic Engine. So I'm just wondering if anybody knows of a controller issue with the Mac version of Magic Engine. Oh! And it controls just fine when keyboard is the default control.
