    I somehow got the QR machine to crash. I know nothing about exploits, or how to execute arbitrary code, but this QR code was created by hex editing a .acnl file and then uploading it to https://www.thulinma.com/acnl/ then re generating the QR code.

    could this lead to a new entry point? I left the debug info at the end of the video.

    this explains why Sable would only let you use the machine if she really trust you she knew people would find an exploit

    it might be possible to get an exploit out of this, however, just because the games crashes after scanning it, does not mean that it is an exploit. It might be, it might not be.

    If it does, make sure you release it after the update.

    It's not about crashing the game. it's about finding the exploit in the crash

    As smea once said, crashes can lead to an exploit, but that only happens in very few cases

    Hmm... Maybe a dev could look at this? It might be a big enough crash to do something amazing!

    Well he's a developer of a big NTR cheat so he would have the capability to create a big enough exploit. -.-

    Crash does not mean an exploit.

    True. But a crash does mean a look-into

    It isn't enough to crash the game, you gotta know exactly what's causing the crash. You can throw garbage data at anything and expect a crash. You need to know if there's an overflow of some kind where arbitrary code can be executed, or some other kind of vector. Also, this has been said hundreds of times before, but a QR scanner doesn't automatically imply the game is vulnerable.
