Edit: Problem solved, although a question still remains (see posts below). Thanks to all who responded! Hello guys, need your help with this one. My son got a DS Lite with an AK2i that works perfectly. We wanted to get the same setup for his brother, my wife bought used from somebody on CraigsList. Unfortunately, when I move the microSD from the old AK2i to new AK2i, the DS will not recognize it ("no DS card inserted"). I got a new microSD, put AKAIO 1.7.1 on it, updated with the newest loader - same effect: works on the old AK2i, does not work on the new one. Please advise. Thank you!
