Just thinking a bit more about #ENLBufferPwn for #WiiU, and I actually just went back to wondering why the Mario Kart 8 exploit video was privated, and this could be possibly #Nintendo having no plans to patch it?
The authors seem like nice people (I've had a few conversations with one of the authors), and I could see them removing it because Nintendo has no plans to patch it, and to protect users who play these games.
Purely nothing factual rn, but it would make sense.
