Any backstory on this? Was SEGA planning a VMU for Saturn or is this just a concept prototype for DC?

I always wondered why the cord detaches from the 3D pad.

It's probably an early Dreamcast prototype by the looks of it. But it's not out of the realm of possibility that it was originally meant for the Saturn and ended up being delayed until the Dreamcast. I feel a lot of hardware & software development lingers on for years before it actually makes it out to the market. Sometimes products never make it out of Research & Development at all.

I think that this is the early Dreamcast controller.

That's probably an early Dreamcast controller, but the Saturn 3d pad did have a detachable cord (with an actually pretty hefty connector that had a PCB in it), and they did have patents on adding expansions into the controller. I think one was a gyroscope?

Don't forget that early Dreamcast devkits worked using Saturn controllers. So yeah, there's a lot of peripheral R&D originally meant for one console that ends up going to its successor (the steering wheel was originally meant for Mega Drive but ended up coming out for Saturn, the Wiimote was originally being made for the GameCube, etc.)

Kinda what I thought but still wonder why the cord disconnects from the 3D pad. I forgot I had this picture and as mentioned. It seems so a DC prototype.

And Saturn devkits first used 6-button Megadrive pads with a cutout for an extra microswitch peg in the upper left for the L button.

They were meant to be expandable with extra hardware. They had a patent on it with some extra pictures for intended upgrades.

Jenovi on you tube has a pretty good recent video on this. I believe he said there were plans for essentially a vmu memory card, rumble pack, a trackball adapter, and actually a bunch of different kinds of adapters for that detachable cord. The vmu and rumble pack ideas at least were then passed on to the dreamcast.
