Nintendo confirms users’ access to Miiverse “mock menu”, now fixed

One Wii U user (and maybe more) was able to access a Miiverse debug menu of sorts on Wii U. This is something that wasn’t intended to be accessible.

In an official statement, Nintendo confirmed that the “mock menu” was indeed accessed by some users. The issue has since been fixed and can’t be accessed any longer.

“It has come to our attention that some people were able to access a mock up menu on Miiverse following the launch of Wii U in the US. Please note that this was only a mock up menu and has now been removed and is not accessible.”
