If I get this M3 real package here, I would have to get a USB to TF card reader/writer, correct? I mean, Im confused, does the MicroSD card plug into the NDS cartridge, or what? What is the Adapter for? Any replies of knowledge would excite me dramatically. P.S. Is this a good price for the M3 real and 4 GB mem, and what in the heck is a rumble ram pack???
