Yep, this is a giant (and fully playable) Famicom controller. It was on display at Game Party 2016 over the weekend in Japan, and people could co-op play Super Mario Bros. For more pics, check out Gigazine.
Live near Tokyo? Like video games? Oh goodie. Later this month, the Tokaigi Game Party Japan kicks off at Chiba’s Makuhari Messe. There will be loads of games to play as well as an enormous 2-meter-across controller with which you can play Super Mario Bros. Sounds neat!
