Yello,
ON the About page for attract mode I've seen this blurb that mentions gamepad support:
hides the underlying operating system and is intended to be controlled with a joystick, gamepad or spin dial, making it ideal for use in arcade cabinets. Attract-Mode is open source and runs on Linux, OS X and Windows.
However I can't find any info specifically on gamepad support. I'm using Xbox 360 Controllers on OSX. At the moment I'm using an app called Joystick Mapper to just manually bind the d-pad and start buttons on the xbox controller to the up/down and enter keys on the keyboard.
But it's kind of a hassle/another moving part I'd rather not have to worry about. Just wondering if there is native Xbox 360 gamepad support, and if so how that works? I've dug around in the menu system and through the docs, also searched the forum, but haven't found anything.
