I'm using an M3Real clashcart and originally I thought my DS was just not saving one game, however after trying others it will not save anything at all. Even when I turn my DS on and it shows a list of the recently played games, if I play a different game it will not get saved to that list and change it, it completely will not save anything. Does anyone know what could be causing this? I'm going to try formatting my memory card but other than that what could it be?
