This JavaScript code will crash the wii u internet browser on firmware 5.1.2U. This was taken from crashmybrowser.com Navigate here with the wii u browser, then select "Heap death of the blogoverse". I was so looking forward to modding Mario Kart 8 with the original browser exploit, but I carlessly updated my wii u to 5.1.2. 
Maybe some of the more expert hackers can turn this JS code into a way of running C code and eventually game hacking!
