I currently have a Sandisk 8GB class 2, and it works well enough for most games without fail, but some games like Chinatown Wars and Portrait of Ruin have problems. Example: Chinatown Wars will occasionally slowdown while driving and Portrait of Ruin sometimes doesn't want to start up and when it works, a black line sometimes flickers at the top of either given screen. I have 60 games in 1 games directory on my card, so that could be it, but the Acekard UI isn't slow, and again, some games are fine. I'm also pretty sure I have clean dumps of those games as well (they work well enough in DS emulators at least). I hear the class 6 Transcend card is pretty much the best you can buy, so should I buy it or do I actually have bad dumps/should I break up the directory?
