So i just recently purchased a brand new sealed 3DS 4.5 or lower firmware. I have done a lot of reading. I was wondering what i need to use Gateway. Obviously I need a console on 4.5 or less Gateway DS card Do i need an SD card or the factory one is fine? ALSO: Micro SDS? How many and what GB, links to models would be awesome. The rest i will read about setting up. Thanks!
