Hey guys, I'm sorry if this has been posted before but I am really confused. I've tried to look around, but I just don't understand. I have a NDS Lite and a TTDS. I've been just playing games lately. But now I see that everyone is playing online. I wanted to try it too. But the problem is that, I have no clue what I have to do to get online. Do I need to buy something extra? Or do I need to just download something? Could someone please help me out? Any help would be greatly appreciated. Thanks.
