    Hi,

    I understand there is a 2 Gb SD card coming with 3DS, used for internal storage.
    Has anyone managed to fiddle with it ?
    Is it readable on your PC ?
    What's the filesystem, what's the directory structure ?
    If you shoot a photo, does a .MPO file appear there ?
    Can you identify any other file formats (not necessarily by extension, maybe by opening it in a hex editor) ? Or are all files encrypted ?
    What's the format of the video coming with the first firmware update of 3DS ?
    Is the firmware update file itself stored there ?

    Maybe someone could just dump the contents of this SD card (preferrably after the first firmware update), ZIP them and upload somewhere for people to start hacking in ?

    Thanks.

    Yea, .mpos appear.
    Only system files like game and saves would be encrypted.
    The update would not be stored on an sd since it's downloaded and ran within memory.
    Jesus on a fucking motorcycle.

    Nintendo doesn't have their own brand of SD cards... It's probably just an empty SD. Nothing special.

    They don't have their own brand = Using others.

    Nintendo doesn't own Toshiba.

    You're sure or you're just guessing ?
    What about the video clip that comes with the first firmware update, is it stored on the SD card ? Is it encrypted ? What's the size of this file ? Does it use any standard video container / video codec ?
    Are you sure savegames are stored on the SD card, not on the game cart like in the case of DS ?
    Can you even use the 3DS when the SD slot is empty ?

    Perhaps they got a good deal from Toshiba since they were already using one of their chips inside the 3DS.

    Kingston is not an actual manufacturer, they re-brand other cards and sell them.

    Who cares if it's Kingston, Sandisk, Toshiba or any other brand ?
    3DS is not a DSLR nor a video camera - doesn't require extreme transfer speeds.

    Going back to the main subject, no one would even include a directory listing of his/her SD card ? Just the folders + filenames ?

    They have had a deal with toshiba since gamecube so it wouldn't make sense to start with a new company.

    It's a totally standard and changeable SD card. There's just no way it's used for vital file storage.

    Let's not derp.

    It's just an SD card. The only thing special about it is that it's supplied with the console.

    I had to say this...

    You mad.

    It's probably going to be used for all the downloadable content - e.g. additional costumes for DoA. This means that it might be possible to exploit these (like savegames) to cause buffer overflows and execute custom code.

    Another important thing are video clips. If anyone can determine the format 3DS is using for videos, we could be able to encode & watch pirated XviDs.

    And who knows, maybe firmware updates are first downloaded to the SD card, verified for integrity and only then copied to NAND. If anyone could interfere with this process, it might lead to opening a door for custom firmwares (I know crypt keys for signing firmware updates would still be needed, but anyway).
