So it's basically what it sounds like, an SNES with a Sony CD unit attached. Interesting that you need that cart plugged in to us the CD functions. That might have been just a proto-type thing, though.

This was still interesting, even though it's just a SNES with some added RAM via a cartridge. If this was anywhere near the final design, I'm glad this never came to fruition. It really wasn't anything special but it would have been better than CDi. It would have collided with Nintendo's Ultra 64, and make a really muddy generation for Nintendo.

Can't wait for next week's repair. Maybe Metal Jesus will look into getting his 64 DD blue cartridge looked at.

I think that's very similar to how the N64 

DD ended up working, at least with F-Zero X, so perhaps not. That might've been intentional as a piracy measure. 

Can't see video in the OP but did you mean Ben Heck from the Ben Heck show?

Also just so people know, this is the only prototype that's ever been publicly seem for the Nintendo PlayStation.

Thx. Part 1 was very interesting.
