    What is their purpose?
    Usually, about half the time I download a new homebrew, I am treated with the regular .nds and then either a .gba.nds or a .sc.nds
    Do I need to have these other files on my SD card, and if so, what purpose do they serve?
    Thanks, Dwight

    you only need the standard .nds file
    sc.nds is for supercard?
    and gba.nds is for.....other flash carts[

    .gba.nds is for slot 2 cards that can boot slot1
    .sc.nds is for old supercards

    Just wondering,do new supercards(DS one v3) run .sc.nds files?

    I'd check myself but I can't be bothered.

    There's no such thing as a *.gba.nds file, at least not in any release I've seen. There are however *.ds.gba files.

    It all boils down to a small header file that's a couple hundred bytes long. Regular *.nds files do not have this header. *.ds.gba files do have this header, which allows them to be flashed to old-school NOR-based flash carts and executed that way. *.sc.nds files are the exact same as *.ds.gba files but are renamed so that the slot-2 Supercard products will launch them in DS mode. The slot-2 Supercard used to need that header to launch correctly, but after a certain firmware update this has become less necessary.

    Basically, if you've got a slot-1 device, use the regular *.nds file.
