My sister is going to send this game to my son, but all three games have been played by her family. Is it possible to wipe out the three games on the game so that when my son starts to play, it's as if no one has played it before. I do hope this makes sense. I would be very grateful for any help here. Many thanks.
Then I have misunderstood the question - Game played data is held on the machine not on the game cartridge if you take the cartridge and put it in a machine that has never played it - the game looks unplayed.
I have two DSI's and the game data doesn't transfer.
