The 64DD is one of those infamous little failures that lives in a special hall of shame among Nintendo fans. This N64 peripheral launched, after many delays, at the tail end of the console's life, received just a handful of games, and was discontinued barely a year after its debut. Still, Nintendo's desire to see the 64DD succeed seemingly had the publisher coming down hard on the studios it had contracted to make games for the device.
Released exclusively in Japan on December 11, 1999, the 64DD was a disk drive for the Nintendo 64, adding support for rewritable storage disks on the console alongside a real-time clock and internet connectivity options. As it suffered years worth of delays, many games planned for the accessory – notably Pokemon Stadium and the Zelda spin-off that would become Majora's Mask – were eventually converted to pure, traditional cartridge releases.
