    What happens if I boot my system in to Gateway mode and perform a system update BEFORE selecting "Format emunand" in the Gateway menu? Does it update the sysnand even though I am running in Gateway mode?


    Here is the predicament - I own N3DS MH4U edition and have significant playtime in it already. I don't want to use "Format emunand" because that will wipe MH4U and my saves off the sysnand. All I want is to have an emunand that I can use for everything else, while preserving my current sysnand and MH4U cia install / save data.

    From what I can gather this seems like an almost impossibility for some absurd reason. The thing I was going to try is just booting in to gateway mode and performing a system update there, hoping that it performs the update in some emulated environment (even though I never chose format emunand) while leaving my sysnand intact.

    Please advise, until I can figure out a way to preserve my sysnand / progress its back to Sky :shy:

    Yes, this will update your sysnand if you update without formatting emunand.

    You could also format emunand on an empty sd card and then extract the emunand from the sd card and inject it to the one you are using for your 3ds.

    Are you certain this will work? How does the Gateway card determine which nand folder to load from off the SD card if two exist, how does it know which is emunand?
    If I try your suggestion, is their any way to extract my MH4U save from my sysnand.bin backup and inject it in to the emunand?
