Just out of curiosity, what is SSFIV? Don't quote me on this but you should just get rid of Xpadder because it is doubling up your inputs ( you only want one set of inputs). Most games with MAME, at least have the controls configured for a joystick with buttons, but that is only MAME. And if you want something a little more newer ( N64 or Dreamcast), you just need to configure you controls for the controller the emulator is using, but not each specific game. Hope this helps.
