I've been trying to find the answer to this for a few days, but have had no luck, so if the solution already exists, please point me to it. I have a Supercard DS One that I put the latest OS on and every other game works fine, but whenever I try to play Contact, it freezes just after the menu. If anyone is familiar with the game, I hit "F1" twice for New Game. The screen goes black, a few music notes play, and then it freezes and the note keeps playing with a black screen. I've found the compatibility list that says that the game should work fine. Any help would be great. Thanks.
