Hi I just got an N-Card from Dealextreme.com (http://www.dealextreme.com/details.dx/sku.2069) The card seemed to work perfectly. It played all games. Some would only work if I selected the right type of save format. I've read though some of the threads here and nothing seems to exactly match my problem. Games initially saved fine. I could save, then return to it later and load. But only for a short period of time. Then it just resets and there is no saved file. I've tried turning off, going to USB mode, saving the .SAV file and returning I have tried updating firmware to 1.45/2.54 (didn't work by holding up, L, R, then A and B, as I got a USB Block sign- instead I formatted the disk and just transferred the new xmenu file). I have run a battery test which passed. I have run a save memory test which also passed. Am I doing something wrong? Should I be soft resetting after saving? Is it the ROMs I use? Or is it just a bad card? I would be so grateful if anyone can help. Cheers!
