    My question is... how? Or even, is it possible?

    I have a retail copy of Senran Kagura 2, and dumped that using the cart dump feature on gateway. I also dumped the save data using that same method. I then put the backed up save file into the root of my SD card where all the other saves are stored, and named it accordingly. (00040000000FB100.sav)

    The problem comes that now that I boot up the .3dz it forces a format of the save data. I've tried using savedatafiler but it just reads the game as broken. I'm running gateway 3.1 on US N3DSXL 9.0 sysnand, 9.5 emunand.

    Any help with this one? :(

    Size of your save ? If 128kb no way, only 512kb are supported with gateway...

    ;)

    My save file is 512kb.

    I'm still trying it in the same ways, and it still goes and formats the save whenever I start up the game. :unsure:

    Sounds like that game is using the newer 6.x save crypto, in which case the save will only be readable in classic mode or on sysNAND as GW mode reverts it to the 2.x save keys.
    There's currently no way to decrypt such saves that I know of.

    Yep. Hopefully either Gateway will release some fix (some sort of encryption toggle for advanced users, maybe?), or KARL3DS will be a stepping stone for a new tool to extract newer-encrypted saves
