    Is it what it says on the tin?
    The save file is written directly to the 3DS NAND? Does this mean people sharing retails carts won't have access to other's game saves?

    Why would this make it so much harder to play on the console as a ROM file now we have emuNAND?

    From what I know, NAND save games do not have a separate save chip. Instead, the save file is written to the chip that the game ROM is stored on. So you can't just redirect all accesses to the save chip to some .sav file, you need to do it a bit differently and they're still working on that.

    You can look at it like this:

    Most normal games (eg. FE:A) have two "sections" of the gamechip - the game itself and the save partition, which stores the .sav file.

    Gateway works with these because it can just tell the game that the .sav is on the SD.

    NAND games, however, have only one chip - the save is stored on the same partition as the game. Therefore, Gateway cannot emulate them.
