The 64DD (ロクヨンディーディー Roku Yon Dī Dī) (DD being short for Disk Drive and originally Dynamic Drive) sometimes referred to as the Nintendo 64DD is a peripheral for the Nintendo 64 game console. It plugs into the N64 through the Extension Port (marked EXT) on the Nintendo 64’s underside and allows the N64 to use proprietary 64 MB magneto-optical disks for expanded data storage. Although it had been announced before the launch of the N64 the 64DD’s development was lengthy.
