This is entirely dependent on what game you are running. Some games it doesn't do this in at all. (FF7 and Chrono Cross do not for example). Bottom line I suggest you CHECK wormies COMPATIBILITY list before running a game so you know what might happenMy MDECs are really screwed up, for every game i have played, movie has multi-coloured blocks on the right half of the screen, and sometimes the movie just ends while playing and goes into the game, or my computer freezes.
Does anyone know how to fix this?
