I was wondering about that as well. i do quite a lot of emulation, but mapping controls on OpenEmu is next to impossible. If someone has any idea of how to do this that would be awesome. As it is, one can play the games just fine, but the controls are set up in a very strange way if you're trying to use a joystick or any other type of controller. If you use the keyboard you're fine, but when using a joystick of any kind it gets a little strange.
