    just a question here, we can make custom GBA GBC GB games to run like VC...
    what if we extrct the save file of these VC via savedatafiler,

    will the save file produced by VBA and other GBA GBC GB emulator compatible to VC?
    For example:
    i have 2 save data...
    1st save data is from VBA
    2nd save data is dumped on 3ds using savedatafiler

    can i replace the save data dumped on 3ds using svedatafiler with the one on VBA?

    It worked for me with a save from VBA-M. Just export your VC save with SaveDataFiler and replace the sav.bin (that's what the file is called IIRC) with your emulator's save file, then re-import the save file.

    You can't extract saves via savedatafiler, at least i couldn't. So no public way to extract/inject saves to VC games afaik.

    I stand corrected then. I tried several times, but savedatafiler failed. I only tried GBA games though.

    How? SDF says that the save is broken. Therefore I'm unable to import it.

    Are you trying to import it or export it?

    @reprep GBA games could be different, I don't have any of those

    Hm, are you trying a GB(C) or a GBA game? Are you using a CFW or Gateway? Also, are you using a legit VC from the eShop or a custom one?

    So, is there any way to do this without having to have a gateway or other hacking things? As I don't have any of those things and I just want my save for Kirbys amazing mirror from the original cartridge (I have the save already exported to my pc)to work on the 3DS ambassadors version.

    Edit: I have a New 3DS and an Old3DS, but all my data is on the new one

    GB and GBC work flawlessly for me, I'm using Gateway though, maybe there's a difference

    You can do it easily with ninjhax/tubehax/ironhax+save data manager.
    Just be sure your using the exact same SRAM format (endianness and size) and that your VC has not an automatic restore point created (you can delete it by entering the game and powering off the console).

    My first save injection with save data manager was with my retail Kirby's Star Stacker cartridge SRAM (extracted with X-Changer), and worked perfectly.

    I now have the tubehax and save data manager, but the only thing there is the system settings.. when I choose that there is an error and I have to press x to close and return to tubehax. What am I doing wrong? I only have legitimate games on my system.

    Thanks that helped :) I guess I'm now officially stupid xD
    Another question; When I choose my desired game (Kirby and the amazing mirror) the top screen is black and the bottom screen is red and nothing happens :/ What should I do now?

    Thanks anyway, will try another game to see if it does the same thing.

    edit:
    Tried pokemon rumble world and it works perfectly, I even gave me some diamond :)
    Why it doesn't work with kirbys amazing mirror, I don't know, but I will keep on trying (wanted my savegame since the ambassador games came out xD)

    Can't remember the filename, but it could be that one.
    Just be sure it's exactly the same size as the SRAM (most of GB games were 8kb, a very few were 32kb).
