    recompiled games without the encryption. mostly a problem for N3ds, because emuNAND goes only up to 9.5

    its for games that you had to visit the eshop to run (going into the eshop would then uninstall all unofficial cia's)
    with the cyrptofix, the games run like normal without having to enter the eshop

    I have no idea where you got that from, eShop has nothing to do with encryption does it?
    I don't know what cryptofix does, so you may be right, in that case then cryptofix is rather misleading.
    But...
    Going into eShop will only delete DLC and theme CIAs. Still pretty annoying though.

    Same here, nothing deleted. Maybe that's only if you go into the eshop while in classic mode not emunand mode.

    The eShop (or to be precise, the title information obtained via the ninja server) saves a crypto seed that is required to make parts of the decryption of some 9.6+ titles work.

    Can you be a little more precise (if you have that from your own research)? What I'm thinking is that it's nonsense that for every new eShop title from now on a "cryptofix" will need to be released; wouldn't it be easier to have a installer and just get a seed.bin with every title. If that'll work, once standardized, it will defeat the purpose.

    Main problem with that installer idea is that someone needs to find out:

    • where/how to interact with the seed db (http://3dbrew.org/wiki/Filesystem_services#SEEDDB has at least some info, but no command headers)
    • how to coerce the ssl module (probably used via http module) to use ClCertA as client certificate when accessing ninja OR if the ssl module coercion fails, a way to decrypt ClCertA
    • how to write a tool that puts all of this together

    The seed info is available on ninja independent of whether or not the title in question was purchased or not, but ninja requires ClCertA to access.

    I dunno, but when I installed the Ace Attorney: Dual Destinies DLC, it was deleted after I went into the eshop.

    That's news to me. There aren't many 9.6+ titles yet though :P

    Where did you get that nonsense? That doesn't happen ever. Well, the icon might disappear from sysnand if you try to run unofficial stuff without signature checks patched out, but nothing gets deleted. It will either come back after running a CFW and stay there, or you'll have to unwrap it every time you enter CFW (usually happens with out of region stuff, or when and emunand is used, but linked to sysnand).

    Consider yourself unlucky then, because countless others have never had that happen. I doubt you would ever want to play around at all after that, but it would be interesting to compare free space on your SD card before and after (to see if it's really deleted or just the tickets, or ??). And did it happen after you bought some legitimate stuff? I always remove things from data management and I always visit the eshop, but my stuff doesn't get deleted. The icon will go away if I try to run something straight from a cold boot, but I get to unwrap it again when I enter a CFW mode.

    I can confirm that my unsigned themes and dlcs get deleted if I visit the eshop, but not the games.

    The CIA was rebuilt to remove the 9.6 encryption for example a crypto fixed version of the binding of isaac.
