wrong again my little friend. Do you have a 64. did you look on the bottom, dolphin goes there with its full isdn internet support and a whole new engine (which i dont know exactly what it is but its more powerful than dc and psx2.) its supporting the 64 but yes it comes as its own system and can be played alone but is meant for attaching to the 64 so people wont throw it out or nothing.
The dolphin is a completely different system. The port on the bottom of the n64 is for the n64DD that never made it to north america. It is a gazillion times more powerful than an n64 even more powerful than the psx2, not by a lot though. You probably could attach the two together but why. the same port is on the original nes. Are you gonna hook all 3 together man your dumb.
Okay for starters Dolphin isn't the name of new next generation console from Nintendo. Dolphin is a code name for the project. The Dolphin will be a totally new system. It is sort of like an answer to the Dreamcast and PSX2. It will use DVD technology. It has nothing to do with the N64. It also wil not play N64 games because it is not using cartridges, it is using DVDs. So to get it strait the Dolphin is an entirely new system from Nintendo.
