Answer to: Why won't my son's Nintendo DS read any games?This could be a nubeeee comment. My wife just got a ds light with around 15 games, separate case etc from the charity shop for £10. Turned it on. Inserted game and it didn't see the card. With no instructions. As we all do, turned to Google and found this thread. So cleaned contacts etc, etc. Still not seeing the cards. However, insert a card and then turn on and it sees and plays them fine.
