Ow, I need a joystick. My arm has a cramp after just half an hour. In terms of ease of control, this is the second worst D-pad I've ever had to use for a Capcom fighter. But at least the worst one, the Dreamcast D-pad, never gave me a cramp!
One more thing: is there a way to get the original stage backgrounds? I can't seem to find any such option, and it's really weird seeing the original sprites against HD backgrounds.
