    Don't get too excited. It's a minor flaw in the savefile encryption. It probably isn't going to lead to anything.

    A minor flaw is the same as a major flaw if it lets you decrypt (and presumably re-encrypt) savefiles. I agree, it's probably not going to be useful by itself, but it's still a prerequisite for a lot of the things we'd like to be able to do on the 3DS. I've heard that saves aren't transferable because each save is encrypted using a system-specific key, but if we're able to decrypt them then we can make them transferable.

    Also, if you can modify savefiles you can start poking around for buffer overflows and other exploitable bugs. I really hope Nintendo has had a few words with their third-party devs (and first-party devs, for that matter) asking them to triple check that ALL buffers in savefile reading code have overflow protection given how badly they got bitten on the Wii, but devs are still fallible so it's worth checking.

    I wonder what the "slight flaw" was, anyone have any more info yet?

    That was posted on twitter 21 hours ago, which is before April 1st even here in Australia so maybe it is true.
    I wasn't aware that anyone had even found a way of extracting save files yet.

    Edit: Looking at that twitter account there's a new post about that same fail applying to games too.

    Because it is in the SAVEFILE which means it's in the save file and not in the game itself

    Where are the saves saved? Cart, Internal, or SD?

    Could this lead to an exploit? Possibly... The original wii exploit was taking advantage of a buffer overflow relating to Epona's name... The easiest way to test is to simply input a longer name than should be possible and see if the game crashes. That wouldn't be a guarantee it'd work, but it would tell us if there is any possible way to exploit it, or if the game would simply truncate the nick to fit.
