Hello, i want to ask about unusual problem happen to my friend, i just give him my sky3ds blue button which is fully functional to me. a good condition. but, when he tried to use it just now, no games is playable as it will come out as "gamecard was removed" error as he open any games. Except,,,only pokemon x is playable, which i do not think the sky3ds is faulty.... can anyone with same problem help? thanks very much.
