Well, heres the thing, with my 1GB kingston micro sd card, everything transfered perfectly, But for some odd reason my 4GB*Its actually 3.79GB, i felt cheated) Sandisk, seems to have problems transfering larger than normal files. Like today i transfered a movie i converted into DPG. And it took me 5 trys to get it work. When i tryed to put in the newest kirby game, it doesnt seem to accept it and disconnects itself before it can finish. And since the cycloDS site is down, i need help trying to get it to work. Do i need to format it? Or what? Help!
