    Hey, why don't we just simply rework the payload into a Download Play app?

    It does not work like that.

    If we can do it within the browser, we can most likely do it through Download Play.

    I don't think using too many objects or polys in MK7 will make an exploit possible, however, MK7 tracks have yaz0 and sarc compressed. If MK7 doesn't check for the decompressed size of the file, then a buffer overflow exploit may be possible. For some reason, MK7 programmers decided to send tracks from the main cxi instead of putting them into the dlp cia, but that may also mean they had put extra effort into preventing silly exploits.

    As mentioned before, any executable data has to be signed in order to be executed, sending a payload will only make the client 3ds to prompt an error.

    You actually make a good point. But since MK7 is actually an early 3DS game Nintendo probably didn't do anything to prevent exploits since *hax didn't exist yet. How could we inject desync code...?

    Off Topic, but...

    Hey guys... I may look like a total noob right now, and I get it: you can't download play unsigned games... but... what about sighax (please don't flame me if I get this wrong just explain it simply...) since we could sign our own cias and cfw and whatnot using sighax, couldnt we sign some kind of data that we made to downgrade then send it over through downloadplay? The target 3ds would recgonize it as a legit piece of software and accept it right? Just my two cents, although probably wrong.

    Sighax only works with bootroms :P
    Also, the same downgrade problem is applied here. You can't install older versions of the titles already installed.
