Beat arcade mode once to get theater mode

Here is a nifty little tip for all those gamers out there having a hard time beating the computer, first off this trick really only works on normal and a difficulty above that. First pick Paul Phoenix, when the match starts all you need to do is land a jump kick (forward + left kick) then as they are in the air descending to a left jab (left punch) and immidiatly after that do Pauls power punch (back + left punch and right punch simultanously) and the computer will roll and stand up right into it! Walla 1 round won! P.S. sometimes it doesnt kill them, so after it hits them just double tap forwards to run towards them and when you get close enough hit right kick to slide.
