I'm trying to backup my roms. I followed this guide: http://teamcyclops.com/forum/showthread.php?t=1942 I can get to where it says 'switch carts and press A to begin backup'. None of my carts work, not AC:WW, not Mario Kart DS, not Mario 64 DS, etc. It says cannot read card. I thought it was maybe my 3DS. So I switched to my DSi, same problem. Switched to my DS Phat, same issue. Help?
