In the late 1980s through the early '90s, Nintendo and Sony, now two of our biggest video game rivals, worked together on a potential console that would've changed gaming history forever.
The prototype looks like a Super Nintendo with an attached CD-ROM drive, and would have played both standard cartridge games as well as CDs. But did you know that they had a huge crossover back then before even Sony launched its very first Playstation?
When Mr Olaffson left Advanta he left the prototype behind, and it was later acquired by former Advatna worker Terry Diebold when the company went bankrupt.
There doesn't seem to be any question of whether the console is the real thing, as Diebold and his son have been touring it around fan events in the United States for a while now, where it can be seen to run both SNES cartridges and CD-ROMs. It is a Super Nintendo device that can be played with standard Super Famicom cartridge games that can also run games using its built-in CD-ROM device.

Videos shared on social media purport to show bloodied protesters running and hiding in the university's restrooms and library. Several students were injured in police action during a protest last week by students of Jamia Millia Islamia in New Delhi .
'At one point this dual-branded prototype's existence was mere myth, ' Heritage Auctions says on its website.
The auction will be conducted by Heritage auctions, which is the same company that sold the extremely rare special Super Mario Bros. And we're not trying to start any intra-family feuds here, but how exactly does the son lay claim to half of the money?
The "Play Station", as it was dubbed by Sony, is expected to fetch a pretty penny when it goes on sale February 27. It's the ultimate prize for collectors, as prototype consoles from that era are truly rare and can usually be counted on a hand that has been fed through a woodchipper machine.
Heritage Auctions has recently sold a lot of expensive NES games though, including sealed copies of The Legend Of Zelda for £15,000, a sealed Donkey Kong 3 for £33,000, and a copy of the original Mega Man for an eye-watering £57,000.
Mr Diebold has had the SNES PlayStation in his possession ever since, and has toured it across the world at vintage game conventions before finally deciding to put it up for sale.
'In the case of this particular item, since it's never been sold at public auction before, there's really no way to tell'.
