    So I backed up my Project Miria cart through my Gateway and instead of giving me a single .3ds file... It gave me two files. A .3D0 file and .3D1 file and both are around 2 gigs each. This is new to me. Can someone explain why?

    because that is how they do it with big carts.

    the person didn't ask what to do with the files, he just asked why gateway does it like that.

    And once they know why the backup utility does that, the next question they'll ask is what they should do with it.

    Maybe. It's possible that they know how to put the files back together but was just curious about why gateway does it that way. Personally, I was hoping they wanted to know how to fix the rom so they can use it, and I was hoping to drag the process out as long as I can since they didn't just ask that to begin with. But now they have all the answers and probably won't post here again...

    Now now everybody. I'll play devils advocate.

    Do I even need to combine them back to 1 large file or can I just put both files onto the root of the sd card?

    You can play them in that format, but if you want to edit the header or make it into a .cia, you'll need to put it back. Not sure if that game has online or not.

    I'm just messing and yes you can put them on the root of your card. I have always combined them myself.

    Gotcha.

    So to join into 1 file, it is...

    copy /b mirai.3d0 + mirai.3d1 mirai.3dz

    Exactly like that... spaces, plus and all? Also... Does it have to be a .3dz or can it be a .3ds?

    yep, exactly like that. you can have it 3ds. 3dz means it can go online if it's an online game. 3ds files won't go online. some extra protection in case nintendo was banning people. Since it's your cart, it has your original header in it and if it's able to go online, you could go online without fear of being banned.

    A few last questions.

    Th sd card I backed the game on was formatted to Fat32. Is that why the game split because of its limitations? If I format to exFat will it back it up as a single file?

    The 3ds only support fat32 cards anyway.

    Thanks for all the help everyone.
