    I was wondering if its possible to build an app for the 3DS to read, store the data, and Restore the data of the amiibo from an SD Card?

    well it must have nfc hardware. but i would assume it's not the full hardware that lets us write to nfc tags, but, is that confirmed?

    If games can write to amiibo, why wouldn't the 3DS be able to?

    It would depend on how well the 3DS would emulate it and if the 3DS can emulate NFC hardware.

    The OP asked about reading and restoring data. It shouldn't require the 3DS "emulating" NFC hardware.

    I think that with the newly found common key that is now possible.

    yeah, the n3ds HAS nfc, so why did you say it is "not possible"? you made it sound like you knew what you were talking about ;)

    And I guess this could also work with O3DS using the NFC Reader / Writer right?

    i don't know. i don't know if they n3ds is 'physically able' to write nfc. maybe the hardware can do only reads, i have no idea.
    but if it can do writes, then sure why not? with hacks it should be possible, but, someone would have to put in the time to do it.

    I guess that would depend on if there is some existing API we can hook into or if we would have to write code for the IR communication.

    Nintendo does call the O3DS device "NFC Reader/Writer", so I'm guessing it can probably write.

    Smash Bros, Animal Crossing etc let you write to amiibo (/cards) in-game. And there's even a smashbroshax if exheader permissions are needed.

    If they were read only they wouldn't be able to hold your Smash fighter info, for example.

    It's possible, but that's the only area we actually want to write on anyways.

    Yeah, technically there are areas not writable. Some are pages set by the factory, most are locked pages, dynamic and permanent. For example the regular lock bits can be set, but once a bit is set to 1 it can't be set to 0.

    Most of the Amiibo NFC is actually writable. There are several areas that aren't: all of the pages that deal with standard NTAG configuration are locked, and the portion of user data that stores the character id. Most of the remaining sections are encrypted though. I'm working on an android app that would do essentially exactly what you described.

    Right, pages 4-10, 16-17, and blocks 16-31 (the latter two defined by the dynamic lock bytes).
