Nintendo 64DD

The 64DD, more commonly known as the Nintendo 64DD, was a peripheral for the Nintendo 64 released in Japan on December 1st, 1999. The add-on allowed the console to read 64 MB magnetic disks instead of cartridges, as well as, when coupled with the Nintendo 64 Modem, provided access to the internet through a proprietary online service known as Randnet. The peripheral was deemed both a critical and financial failure, being discontinued February 28nd, 2001 and never given an international release.

While only 8 games were released for the 64DD, at least 60 others were announced or planned for release before the add-on's discontinuation, including an expanded re-release of Super Mario 64, and a sequel to Super Mario 64 tentatively known as Super Mario 64 2.
