Well before I start let me just say I had never used a flash card in my life. But I am a real quick learner with these type of things, since I know a lot about computers. Now I got my Acekard 2.1 in mail 2 days ago. I got it from Modchipcentral. The reason why I think the Acekard is faulty is because my Nintendo Ds won't detect/recognize the Acekard AT ALL. I've gone through MULTIPLE guides from these past 2 days, from you-tube videos and even guides provided in this forums. I followed each step exactly as described. I have even tired used both Acekard's official os and Akaio's. I've formatted my 2gb Kingston micro sd multiple times from Fat32 and Fat. None of these seem to work. Every time I stick my Acekard in my ds it is not picking up on anything, but when I put in my regular games it does. Am I pretty safe to guess that I received a faulty unit? Even if I hadn't done anything to my Acekard, and just stuck it in to the ds straight from the package, would the ds be able to detect the Acekard? Because it has never responded to anything from the beginning. All I get is the nornal pictochat and ds download play options. Thank you for your time and consideration.
