While fighting in a single player battle, press Up(2), Down(2), Left, Right, Left, Right, B, A. If you entered the code correctly, you will hear a sound. This will allows you to pull off special moves with easy movements. For example, while playing as Ryu press Forward + Punch for the Fireball, and the Fireball move now does the Dragon punch. This makes the game much easier to play with the small D-pad. Press Select to toggle "Easy special mode" on or off.
