Hi, i goy my supercard miniSd and super key for my DS lite 2 days ago. I Downloaded the mario kart game and It works fine in single player mode. But when i want to start a SIMPLE mode mutiplayer game, My friends cannot run it... They can join in the game, but once i press confirm, and they finish Downloading, the white nintendo screen just shows up on their NDS lite, and just freezes there. I have formatted the .NDS file with supercard. THey dont have a superkey or super card, only i do. Also, do i also have to add the .NFO file? whatever that is? *it was together with my .NDS file* thanks.
