As the title suggests I think something must be wrong with my card. I can backup nand, I can launch retail games (region free) through classic mode, Diagnostic gives me OK! on everything but SPI (Beta bug). But whenever I want to launch a game I only get the message that the card was removed. I tried three different SD cards, tried it on other 3DS, all the same. It must be the card. My reseller (Elewelt.com) doesn't reply and ignores my messages, is there any way to fix this? Or is the card simply faulty and there's nothing I can possibly do?
