NeoGAF member Trike managed to accidentally "hack" Miiverse yesterday while dicking around with his Wii U GamePad, stumbling onto a weird little debug menu and temporarily going drunk with power before losing his golden touch. 

"I can even access something with the name 'prototype' that seems to be the actual prototype Miiverse in Japanese," he wrote. "Apparently John Lennon is still alive and is posting on the Japanese Miiverse. Most buttons that I tried don't work (Acid_Test?) so I thought, hey, maybe GAF could have fun with this or translate it. That is when I found the admin list.

"At first it asked me to sign in, because my login information didn't match. Then I pressed a button and it sent me to a list of admins anyway. They had buttons in the same row as the names, and I could 'regenerate password' or 'Delete Admin' or something along those lines. I didn't do it it because I didn't want to risk getting my god damn Wii U banned on day 1."

As he dug around, Trike discovered some test forums, including listings for a number of unannounced Wii U releases -- including Resident Evil 6, Dragon Quest 10, Metal Gear Solid, and Final Fantasy 3. Most interesting is a game listed as Yoshi's Land Wii U.
