In Reality Arc on the Promised Arc, (at least when I downloaded v.29), the cutscenes froze at some points. Sometimes the characters would move one step and stop, sometimes the characters appeared and don't move. Sometimes, it would black-out "or try to" and stay on the same scene rather than move to another, but you can still see the dialogue progress (No picture D;)
In the dimension map, the maze before you fight Zeto, you can cheat by running into the empty space and spamming your menu button. Then spam to move and open up menu again. Repeating this will replace you at the step you were about to move to, while keeping your sprite there.
