Go to Arcade mode. If you lose to your rival character the game (if you wanted I-ISM pluses), drop the continue numbers to 0 very fast. You will get a game over with a 'Try Again' on the middle. When you move the D-pad the buttons are glitched. If you want to cancel it, you can press Home and get out of the game or by turning the power off.
Easy super combos
Go to the "Button Configuration" screen at the options menu. Then, go down to "Select" and "Taunt" should appear next to it. Press Right until it reads "S.COMBO1 LVL1". The number after "S.COMBO" corresponds to what super combo you want to use. The number after the "LVL" represents what level you want the move to be. For example, to have Ryu use his Shinkuu-hadouken at the highest level, scroll until it reads "S.COMBO1 LVL3". This can also be done from the pause menu.
