Ok, I've got a Wi-fi dongle and managed to connect my DS. I've got it working with Mario Kart DS and Pokemon as well... But I'm having a problem with the ROM of Professor Layton. When I try to connect, it says "Error 20109, please contact Nintendo". So... it's just me with this problem or it's Nintendo having a problem with this game?? Or there's something I don't know, like, downloading the DLC on a specific day or something like that? Thanks in advance.
