Yes i know this might be the wrong place to ask this but its the bets one i could think of. Anyways...
Where can i find the script where it shows the speakers face when the person is talking.
In the RMXP Scripts Database. There are a couple, but Seasons In the Abyss' Letter by Letter is probably what you're looking for.
the new one doesnt work though. it crashes the game when it starts.
Try posting the error in script help. I'm sure someone could help you to get it to work for ya.
