The unreleased Nintendo 64 Secret Screen! The controller was the brainchild of Dane Galden, inventor of the Game Handler, a 3rd-party motion NES controller. The Secret Screen was publicly revealed in a 1997 issue of Electronic Gaming Monthly, but drama ensued when months later, Sega revealed their Dreamcast and VMU. Thanks to Shane Battye for sending this to us and doing a TON of research!
