Nintendo 64 Disk Drive (partially found unreleased video games for Nintendo 64 add-on; late 1990s-early 2000s)
The Nintendo 64DD is a failed add-on for the Nintendo 64. There are multiple games planned for the 64DD that were cancelled.
Cabbage was a codename of an unfinished game that was being developed by Shigesato Itoi, Tsunekazu Ishihara, and Shigeru Miyamoto. The game would have been similar to the at-the-time popular Tamagotchi, where the player would take care of an unspecified creature, even using the N64DD's internal clock to keep the in-game world running even when the system was turned off, meaning the creature could have changed in the player's absence. The creature was also planned to be transferable to a Game Boy to take care of it when not home, and be shared with friends. Cabbabge was meant to be revealed and playable at Space World 2000, but this wasn't the case, and it was eventually cancelled.
