Hello, I have an original DS (not lite) and I have just bought a M3 Lite micro SD perfect. I did everything I had to do but when I put the Cardtrigde and turn it on I get: warning cannot find card. Please shut down and insert secure Digital card. Or START to continue anyway If I press START I get those red words: " This product is NOT sponsored, bla bla" and it just stays there. If anybody knows what is the problem help me please. I Have read that it works with DS lite and DS. My Micro SD is a Kingston 1GB (japan) I also used a Toshiba and the same problem again.
i remeber now, it may just be that ur sd is just not sitting tightly in the thing. open it up and see if thats the case. ~carefully~ if the sd's work fine, then it must be the m3. does it work on a gba?
