Nintendo is playing down reports of a Wii U owner accidentally hacking into Miiverse's debug interface, the company saying he only accessed a prototype. Nintendo released a statement to GamesIndustry International which says what the user found was "a mock up menu," and that it is now removed and inaccessible.
NeoGAF user Trike claimed to accidentally hack into a debug menu for Miiverse, simply by hitting X over the network's exit button. The user gained access to what Nintendo claims are mock-ups of the system's back-end. Among the things Trike stumbled upon were administrator lists and forum posts from developers. However, the info within his photos does resemble that of a mock menu, with repeated email addresses and messages.
Nintendo's official statement reads: "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."
Interestingly, one of the user's photos shows a list of game-based subforums, with 'Yoshi's Land Wii U' and 'metal gear solid' among them. Of course, if the subforums are part of a prototype menu - one of them is for 'resident evils' - we can't draw anything from it.
