PRETTY sure this broke my WiiU.
The WiiU box reads:

It's been about five days since I first successfully ran Project M on my smash bros. I had left the SD card in the WiiU and played both BlackOps and Mario while it was still in. Mario was the last game I played before turning the system off, and for some reason it stopped displaying the video output and the Gamepad stopped working. Troubleshat with Nintendo for them to be like "lol thats weird, idk what to tell you I never heard of this" but thank GOD my parents got the 2 year warranty at Gamestop. I didn't tell them I installed project M on an SD Card but that's literally the only thing that could of went wrong.
So fair warning to WiiUsers. I'll be chatting with the Project M people later to see if they know any of this.
