“Street Fighter II - The World Warrior” for the arcade does not enable both players to choose the same character and the computer won’t choose the character that you’re fighting with either.
Now, the Super Nintendo version had a cheat for two player mirror matches. Single player fights still didn’t include mirror matches. (I.e. even with the cheat enabled, if I lose with Ryu against Chun Li and then choose Chun Li, the computer will still choose Ryu.)
However, on the Super Nintendo, there is a way to trick the A.I. to choose the same fighter as you. I requires some steps to enable this, but it is possible: Do certain actions and the computer will not notice that he’s choosing the fighter that you’re controlling in the moment.
My question: Is there any way to do this in the arcade version? Two player mirror matches are of course out of the question since the character select items cannot move to the same fighter. But is there any way to exploit the A.I. so that it chooses the same fighter as you?
