Well, it's been an issue for a few months, really. I think it's related to my DS, since I haven't had any trouble before march, when I got my new DS. It's a cobalt/black DS, and whenever I try going online it doesn't work. It connects, but then turns red again and gives me an error code(20109, I think, but I'm not sure). When I looked it up, it told me to call Nintendo. I've tested this with many games, Animal Crossing, Mario Kart, Advance Wars Days of Ruin, Metroid Prime Hunters, and none work. When I tried each of the actual game cards for these games, it does connect online. Also, my old red DS worked flawlessly online as well with my M3 Real. So, does anyone know what I can do to get it working?
