Hey I need help I have got both White 2 and Black 2 on two different DS's right now and I want to replay Black 2 on Challenge mode. By the looks of things I have to send the Challenge mode key from Black 2 to White 2 then restart Black 2 and have White 2 send me the key once again.
But for some reason when I try and do this it says there isn't any keys to send / retrieve, why is this? can somebody help me out please?
