As I understand you can use an emulated NAND without the Gateway card by using gateway's files. Before I go and buy a 4.5 3DS I need some more information about the emuNAND: 1) Can I do a system transfer from my normal 3DS to emuNAND 3DS? 2) Can I access the eShop and buy games on emuNAND? 3) Are there any speed differences between real NAND and emuNAND? 4) What doesn't work on emuNAND?
