Some dude apparently reverse-engineered arcade OutRun (I'm assuming), porting it over to Windows, OSX, and Linux, and added widescreen support, 2x resolution support, true 60fps (arcade version alternates between updating the track and updating the sprites every frame, lol), force feedback, and some other stuff.
And he's working on a level editor, pretty wild!
This is probably now the best way to play OutRun.
