Platform: 64DD

The Nintendo 64DD is a disc drive add-on for the Nintendo 64 that was announced on the Shoshinkai game show (Space World Today) in Japan, talked about by Shigeru Miyamoto and released in Japan in 1999. It was never available outside of Japan.

There was a game by the name of Cabbage which was to be developed and released for the Nintendo 64DD, an expansion peripheral for the Nintendo 64. The project began development in 1992 and was helmed by Shigesato Itoi, creator of the Mother series, with other big name developers like Tsunekazu Ishihara, Shigeru Miyamoto, and Satoru Iwata eventually being added on to help finish the project. Even with this help, it would never see the light of day. It was said by Miyamoto that, "the conversations and design techniques that popped up when we were making Cabbage are, of course, connected to Nintendogs and other things that we're doing now." Those "other things" most likely refer to the Animal Crossing series, as it used many of the base elements said to have been made for Cabbage including the internal clock feature of the N64DD. To this day there are no known screenshots, videos, or demos of this cancelled game.

Nintendo planned to release the 64DD in North America and even manufactured test units with fully translated BIOSes and functional region locking. However, the idea was ultimately dropped due to the add-on's low sales in Japan. Concrete proof of these plans wouldn't become public until 2016, when YouTuber Jason Lindsey (a.k.a. MetalJesusRocks) found a surviving test unit and verified its legitimacy with former Nintendo of America employee Mark DeLoura.
