I have a 3DS on version 4.4 and just got my Gateway 3DS card. I have microSD cards (one 2GB and one 32 GB) So what am I supposed to do now to set everything up? What do I have to do to start playing 3DS ROMs? What about updating to the latest version of Gateway (version 2.3b)? And what do I have to do to update my emuNAND?
