Hi all, Just got my DS lite, supercard lite rumble and superkey for christmas. Everything works great and I have had no problem at all playing games. I tried however to link it up with my little brother's original big DS so we could play local wifi multiplayer games such as Mario Kart, Clubhouse games etc but could not get it to work. He would find my games, start downloading but then when his DS restarted we would lose connection and he would just be left with a blank white screen. Is it possible to play multiplayer using roms? or does he need a superkey/supercard as well?
