A group of guys have released a video showing modded tracks and other neat tricks, here is a quote from the video description:

This work is based on the recently released browser exploit, and some additional code that Chadderz wrote to get arbitrary kernel reading and writing, to allow the browser to edit Mario Kart 8′s memory on-the-fly.

All of this may not look impressive, but it’s merely because we don’t even know where to start; we can do anything now, anything at all! Custom tracks, custom songs, you name it. We just have to decipher the RAM and work out how.

I hope you enjoy this quick look into what we’ve been up to recently, and hopefully more to come soon!

Here is a complete list of what they have accomplished:

  • Making Moo Moo Meadows play its final lap music immediately
  • Making the final lap play no music at all
  • Making the lap 1/2 song into the opening camera fanfare
  • Renaming Moo Moo Meadows to “Hello!”
  • Renaming it again to “Shitty luck course!”
  • Renaming Toad’s Turnpike to Deathpike…
  • Corrupting a font
  • Crashing the Wii U
  • Altering the Wii U menu fonts

And here is the video:


Crediar confirmed today that the browser exploit that we have yet to really see anything about has been crushed by Nintendo with todays 5.0.0 update:


Do not update this update seems to fix a certain exploit in the browser.

In a quick update Marionumber1 has now stated:

People need to calm the hell down. Nintendo did not block the bug in the browser, they simply changes around some addresses. The exploit has not been blocked, I doubt Nintendo even knows one exists. You know what might cause them to know, however? This mass hysteria.

Whilst this is not the first Wii U game to be dumped, the group that dumped it, claim it is the first true dump, here is a quote from the NFO:
