Ever since I updated to the newest firmware, I haven't been able to play Pokemon Diamond properly. Whenever I play, sometime during play the game will freeze, it has happened right after opening, after five minutes of play, after ten minutes of play, etc. The time it will freeze is usually different each time but I haven't had a time it didn't freeze. I don't know if it has anything to do with the new firmware, but all I know is before I updated it wasn't freezing. Any ideas on what this could be?
