I have been using a M3 Ds Real Card and never had a problem programming it, I purchased 2 M3 Zero cards and I can't get them to work what should I do diffrent, please help me as I have 2 kids waiting for them, Thanks!!
Did you install the latest firmware on your M3 Zero? go here http://www.linfoxdomain.com/nintendo/ds/ and look for M3/G6 DS Real and M3i Zero link and whatever is the latest firmware download it and unrar it into your sd cards and you should be good to go after tossing a few roms on there as well, pretty much the same set up as the M3 real itself.
I've actually never delt with a M3i Zero but I do have an M3 Real, but you could try it in a nds folder or just drag and drop like I do with the M3 Real and see which one works.
M3DS real and M3i Zero use the same firmware. If you mean they don't show up at all did you install F_CORE.DAT? http://down.gbalpha.com/GBalpha/Softwares/F_CORE.zip Just put that on the root of the MSD and connect the M3i zero via usb to your computer. It will light up. Give it a bit and let it install.
