My idea for the arcade mode is before and between the fights add a little intro with the two fighters on the Tenkaichi Budokai board.
It's actually, really not too hard. I did it before.You will need:DialogueDialogue boxesetcTrigger an "in between" state by checking for names and roundnumbers.Then, put Assertspecial = intro while changing the animation to the desired ones.Once it's finished, changestate back to 0.Voila.
