    Unless they can provide distinct proof of that they installed these without cfw. It sounds like they are bullshitting you with it.

    They must be Eur consoles. There's no Link Between Worlds legit cia so you must be mistaken there. You can install legit cia with no CFW by having arm11 kernel access.

    Then they are lying. OOT was never pre-installed, so a legit .CIA does not exist. Period. The only way to install any unsigned .CIA is with arm9 access which cannot be achieved through userland homebrew. Only between 11-11.3 did we have arm11 access to install legit cias without CFW; and OOT wasn't one of them Lol.

    You may be getting mixed up. You need arm9 access to install non-legit cias, and arm11 kernel access to install legit cias. This is how we were able to downgrade to 9.2 for a while - we had arm11 kernel access (system titles are legit cias). I think that got patched around 10.7 or something.

    It occurs to me that they may have just grabbed them through the eshop, but I would still require proof if I wers to purchase something like that.

    I am trying to decrypt some of my CIAs so I can attempt to convert them to either CCI or 3DS for use in an emulator to expirement with, but nothing I do seems to decrypt them, Decrypt9wip says it could not find the seed and godmode9 just says it failed. If my 3DS is on the latest firmware shoulden't it have all the encryption keys it needs?

    The titlekey comes from the ticket (which is always included in a cia, but may be bad/fake depending on the source)
    The seed is never included in the cia, that's the whole point of having this extra key -- get an updated seeddb from the titlekey site

    Since the release of B9S, the bootrom [keys] were dumped, and you can also decrypt games directly on PC

    Run FBI via CFW (installed then removed, or ran directly from ntrboot) or via soundhax if on supported version, install cia, profit

    I am curious on why did it fail to get the keys out of my NAND though.

    Wait, you can? I was pulling my hair out the other day trying to figure out how so I could avoid having to worry about doing it on my 3DS itself, how?

    Maybe you never installed the seed? = do you have the game installed and working on the 3DS?


    "The trinity" aka 3dstool, ctrtool, and makerom - actually only the latter 2 in this case
    ctrtool can (apart from other features) extract the NCCHs (CXI and CFAs) from a .cia (or .cci = .3ds)
    makerom can reassemble them into a cia or cci

    HackingToolkit is an imperfect (but passable, at least for regular games as opposed to system titles) user interface wrapper for the above, although I'm not sure if it can do this conversion

    Ah, I was trying those. Issue is though, that the official GitHub for ctrtool and makerom is very out of date for the compiled versions, the last release being Janurary of 2016, where those versions of the tools lack the ability to decrypt CIA files, despite the fact that in source some of them were updated as little as 20 days ago. I wasn't able to find a more recent version anywhere, and don't know how to compile code, pretty much all my attempts to compile them failed.

    I actually posted Windows x64 builds some months ago (which happen to include the 20 day old change) somewhere on the 3DS romhacking section, don't ask me which topic though! :) (I think the word "static" was used a few posts before)

    Found them, but it's still not working :(

    ctrtool gives me the usual screen full of information while doing nothing, except it's not giving me that "unable to find common key" or something like that error it used to give
    makerom tries for a while, but then gives up stating "Failed to decrypt CIA content"

    Am I missing anything else I need in addition to the executable files for makerom and ctrtool to work?

    EDIT: Oddly, I also noticed that the first time I attempt to convert a CIA, it takes a while before it fails, but every time after I attempt that same CIA it fails instantly.
