I feel you bro. If you are having trouble with the inputs, buy the 3DS Edition. All you have to do is tap the touch screen to do an ultras and specials. If you don't wanna do that, practice the inputs in training mode. Example: Ryu's Metsu Hakoken is quarter circle foward twice and all punch buttons. I would go with the 3DS edition. I don't wanna stress my fingers out.
