The Nintendo 64DD (with DD short for Disk Drive) was an add-on to the Nintendo 64, released only in Japan after years of speculation and broken release dates. It had very little to no support from Nintendo, combined with its late release. Only 15,000 units were sold and only nine games were made for it, making it a commercial failure.
The whole purpose of the 64DD is to play online games, which the original N64 didn't utilize. The 64DD is plugged into the underside of the N64, where the EXTension port is.
