If only Nintendo came out with disc drive attachment for the N64, maybe call it the N64DD?
WH-WHATTTT?!?! It actually exists?

They put it out in Japan and released 10 games for it. It flopped, hard. It was supposed to come state-side but they pulled the plug on it in the last minute due to poor sales.
In fact, Legend of Zelda: Ocarina of Time was originally developed as an N64DD title, and they had to cut a lot of the content because the game would not fit on a regular N64 cartridge.
I know, not totally the same as supporting CD roms from the get-go, but Nintendo did actually pursue this, and it didn't go too well.
