So, MH4G came out yesterday and I decided to play it. I'm kinda a noob about this gateway thing. Sorry I didn't post it on the noob thread because I have more than one questions and it will be long. So, first of all, my 3DS is English and it firmware is 4.2.0 U9. Just now I used the rom updating method w/ the rom Super Smash Bros US version to get it up to 8.1.0. Finally was able to play MH4G! But I have some questions about it. I did format the emunand before doing this method. 1. So, if I power off now and repeat the process to get back into GW mode, will it be on 8.1.0 or will I have to update again? 2. I did not back up my nand, if I ever wanted to go back down to 4.2.0 for what ever reason, what will I have to do? 3. I noticed that doing the format emunand, it formatted the SD card, does it delete the game saves and what exactly does emunand do as it did cut my SD card into half? 4. Is there any reason to downgrade back to 4.2.0? Like can I just keep it at emunand 8.1.0 and when new games come out that requires a higher firmware, I can just do the same method again to update and play the newer games? 5. Is there anything I need to beware of as I did not back up my nand? I'm reading on other forums that other's emunand 8.1 turned into real firmware 8.1, I would hate for that to happen. Sorry for the long list of questions and if there is answers already. I did check some threads out. Just wanted to make sure that I know everything and it safe, don't wanna spend anymore money for another 3DS or gateway card. Any help would be appreciated. Thanks for Reading!
