Hello! I'm rather behind on the Gateway scene -- would someone please answer a few questions I have about it? I bought a Gateway months ago, but only used it briefly. Work leaves little time for games. Anyhow, my Gateway card is currently on the last firmware that did not support multiROM; I had to put each game on its own microSD card. I know several firmware updates have been released since then, and it sounds like it's time to catch up. I.) Getting Started with emuNAND --- A.) How does emuNAND work? Is there an up-to-date guide I can read? --- B.) Is emuNAND the same as Gateway Mode? If so... ------ 1.) Is emuNAND / Gateway Mode still activated by the DS Profile exploit? ------ 2.) Is emuNAND / Gateway Mode still deactivated when a DS Game / DS Flash Card is used? From what I understand, emuNAND makes a copy of my 3DS's 4.5 OFW, then stores and emulates it on the SD(HC) Card, correct? The 4.5 OFW stays safely tucked away in the 3DS's System Memory while the emuNAND runs from the SD(HC) Card in its place. If anything bad happens to the emuNAND, a Backup emuNAND can be restored, or a new one can be made from the 4.5 OFW. All right so far? --- C.) How do I update my Gateway? Do I need to update the Blue Card too? --- D.) Once I've updated my Gateway to the latest firmware, how do I begin using emuNAND? --- E.) I bought a 64GB microSD card now that multiROM is supported. It will work, right? --- F.) Will I need a bigger SDHC Card? I'm currently using the default 4GB one. ------ 1.) Most data is stored on the microSD(HC), right? What goes on the SD(HC) Card, besides Save Data? II.) emuNAND Complications Once I've updated my Gateway's firmware, and I'm running the latest emuNAND... --- A.) Can I still play legit Retail 3DS games on this 3DS? What about Digital Copies? --- B.) Will Local Wireless / Local Multiplayer / Download Play work for Legit games? Non-legit games? --- C.) Can I still play legit 3DS games online safely? What about non-legit games? ------ 1.) I heard that it's necessary to change the header data to play non-legit games online. How do I do that? --------- a.) Is Save Data tied to a game's header? If I change the header, must I start over with a new Save? --------- b.) I heard I can port the Header Data of my other 3DS games. Do only certain Headers work? --------- c.) Are there any tools for managing / editing 3DS Save Data? --- D.) Will my old Save Files become incompatible? Must I start them over from scratch? ------ 1.) If so, will I lose my Save Data this way every time I update the Gateway Firmware and/or emeNAND? --- E.) Will System Transfer work? I'd like to send some legit Digital Copies from this 3DS to an all-legit one. --- F.) Confirm or Deny: Anything purchased from the eShop while on emuNAND will be permanently lost if that emuNAND data is lost. Purchases are not tied to NNIDs, only systems. Thanks a lot for any advice! I'm looking forward to making more time to play 3DS games.
