I just got my M3 Simply today and neither of my DS's will recognize it. I get the "No DS Card Inserted" message. I have copied the firmware files (DS_MENU, DS_MSHL and the moonshl folder) over to the main directory of a FAT formatted Sandisk 1GB microSD card with a ROM folder as well. I have cleaned the contacts to both my DS and the Simply of anything that could have been there and have blown out the DS a few times. Every regular DS game i have works fine. Also, my DS is not flashed. Does anyone have any suggestions or should i just try and return it. Thanks in advance.
