On the bottom of the N64 there is a post thing that opens up. Did nintendo ever use this function? I've never seen any use for it
They were going to have a 64 DD drive for it. I think it was something like a bottom disc drive, almost like the one SNES was gonna use before bad business decisions made sony go their own way and make it the Playstation. I can't remember much about it, but I DO remember it was call the 64 DD.
They DID release the 64DD, but I'm not sure if it ever made its way to the states or not. This was at the time that the N64 was already doomed, and there was no more developer support for it. So I really couldnt be sure.
