    well, there are many games going to eShop,
    and we can get download link via PC.
    it means we can get a encrypted rom.
    of cource, this encrypted rom is same to every console.
    I think the 3DS console download game by these steps:
    1.download encrypt game
    2.decrypt with a common key
    3.extract files
    4.encrypt with console private key

    to extract rom, the problem is how step 2 running.
    I guess there are 3 possible ways:
    a) common key is stored in console. when rom file downloaded, eShop application decrypt it with that key, and do steps after.
    b) a random key(one game one key, different game different key) with rom file. like a game save, eShop find the key from downloaded rom file, then decrypt and do steps after.
    c) a key only stored on server. eShop download a rom file, then request key from server via http, and do steps after.

    maybe the way a) is the most we want. the worst is c), we have to know what eShop sends and gets via http.
    is it really working in one of these ways? or other else?

    and sorry for my poor English..... wish it is easy to understand.

    Agreed.

    If you think that no hacker has thought of that, you're wrong. If it was that easy, the 3DS would've been hacked today.

    sometimes it is just a young person who had an idea. for whatever reason they did not think to research the idea before posting about it. go easy on this person, let them know a bit about the current state of 3ds hacking, and then let it be.

    thx for replies first.
    I searched on google but nothing about how eShop processing a downloaded rom file
    (maybe I used wrong keywords)
    of course hackers have much more ideas than me
    sorry I really don't know the state of 3ds hacking now except chip decapping

    Well it's not as simple as that. From what I gathered from your post, I'm guessing you want to play eShop games without paying for them. You'd need the common key, a way to obtain a ticket for the eShop game, your 3DS's per console key, and a way to get around the DRM built into the 3DS. Read here:

    thank you for the explain. well seems that it's nearly impossible to get contents from sd card, in current state.
    and, in fact, I just want to get some resource from eShop roms. sounds or pictures. need not to wait cart dump, and officially.^_^
    so I think that the official rom is just encrypted by common key, maybe not so hard to get decrypted contents.

    Well if you actually want to decrypt the eShop ROMs(also they aren't called ROMs, only the game card images are called ROMs), so you can get game sounds/graphics, you should just forget it. The game isn't encrypted with the common key, the game's ticket requires the common key, so from that you can decrypt the eShop layer of encryption. Now you have the executable, but that is also encrypted, and no one knows how to generate the key required to decrypt retail CXI.

    It seems he isnt trying to troll, and had a legit question. However, he probably should have gone through the STICKIES... Don't ban, just lock the thread please.

    I think that's just a file,that's supposed to be a regular file stored on the SD card,cereal guy.I'm sure Nintendo's no fool,and that is not a ROM.
