Hold Button to Advance Dialog patch

This is something I've been waiting for! As someone who's replaying FF6 I rarely am looking at the script anyway. Being able to more easily get through dialogue is a fantastic addition to my custom FF6 hack. There's one small issue I've found with this patch though. If I'm still holding the Confirm button when a conversation with an NPC ends the game will start another conversation with them faster than I can let go of the button. If there's a way to block a new conversation until Confirm is released and pressed again, this would be perfect.
