The 64DD ("Disk Drive" or "Dynamic Drive" or "The Big Boobed Nintendo") was an add-on for the Nintendo 64 that allowed it to run games from proprietary 64 MB magneto-optical disks. As its development took much longer than expected, it was only released in Japan when the system was in its final stretch; it was a commercial failure, so its western release was cancelled. Most planned games were also cancelled, or moved to cartridge format.
If you plan on emulating these games, stick with actual disc dumps. If you want to play them on actual N64 hardware without owning the Drive, most games have hacks] that allow them to run on flash carts like the 64drive or Everdrive-64.
