I got the acekard cause it was cheap and because I heard great things about it but I've been having too many problems with it. For maybe the first month it was working perfectly, until the DS started having trouble recognizing it. That turned out to be that familiar contact issue. I did the paper trick and it worked better from then on. Few weeks later my Moonshell stopped working completely. Had to reformat the MicroSD and now it's working great again. Now since last night my DS has been having trouble reading the cart again but not like before. Now the screen will go black while I'm playing and say that the Game card has been removed even though it was still tight in the slot. It did that a few times while I was playing DBZ SSW... What is the best hassle-free flash cart I can get that won't consistently give me problems???
