I recieved my M3 (CF) today and I downloaded the latest FlashMe. I put in my PassKey in the ds port and put in my M3 with a gig CF with the FlashMe.nds in it. I held down all necessary buttons when booting up the ds but it doesn't work (FlashMe doesn't boot). I've fiddled around with it for 3 hours and I can't get it to work. I think it might have something to do with my serial number (NU101800035) not being compatible with my M3 but the M3 boots up fine when selecting "Play GBA Game" on the nintendo screen. Am I missing something? Someone please help, I'm lost here.
