I bought a used Acekard 2i on Ebay. I've loaded a game on it and wanted to try it out. So it happens that most of the time when starting my DS Lite with it the card doesn't show up. I need to insert it several times and blow on the card and inside the DS card slot and try many times. So after 5 or so times it finally booted up and I tried Pokemon Black 2 on it. It played for about 20 minutes and then the game froze and I had to restart. Is the card damaged or what is the problem here? Get a new one or is it something I can fix?
