Hi everyone, I am new to this website and Nintendo Ds's in general. I just bought one. after looking through the forum i am very interested in getting M3 Perfect mini-SD with Passcard 3, i was wondering if that is what i need to play download .NDS files. (the games) and how hard is it to use the M3 and passcard 3? do i just drag and drop my .NDS files onto the memory stick? do i need to convert it? and also I was wondering if i use M3 perfect mini-SD that it would save my games? I have no clue if save data is stored on the DS it self, or on the game card or something.. i know these are probably noob questions. thanks.
