My son's DS which is about 2 and a half years old, has gone wrong. When you put a game card in and switch it on, it doesn't recognise that there is a game inserted. It just says 'there is no game inserted'
It has been doing this for a while, but by switching it on and off a few times it would eventually play the game inserted. This trick does no longer work, and would love to hear if anyone has any other ideas!!!
