The world’s only known "Nintendo PlayStation" has sold at auction today for $300,000.

The prototype console was teh result of a failed partnership between Nintendo and Sony in the early '90s. Only 200 prototypes were manufactured of the system, which is basically a Super NES with a CD drive.

The specific device is actually playable, with the auction description saying a few rounds of Mortal Kombat were played on it.

As the only known version of this hardware in existence, the prototype is the gaming world's rarest console, if not the rarest item altogether. There's also the added romance of it representing the final collaboration between Nintendo and Sony before their plans for a Super Nintendo CD-ROM system fell apart over licensing deals.

Pre-bidding closed prior to the live auction today at $280,000—plus a 20% buyer's premium that made it $336,000 in total—though, it had previously hit $350,000 in February. The winning bidder technically paid roughly $380,000 for the winning bid, owing to an additional "buyer's premium" fee attached to the auction.

One of the early bidders was apparently Palmer Luckey, the cofounder of Facebook's virtual reality company Oculus, saying on Twitter in February that he is "on a quest to digitize and preserve the history of physical video games" and that "VR will ensure the original experience lives on forever, but we need to keep these things alive and functional in the meanwhile."

Update: It seems that it wasn't the much-publicized cofounder of Oculus VR Palmer Luckey who walked away with the console, it was entrepreneur and avid video game collector Greg McLemore.

Speaking to Forbes, McLemore, an LA-native, real estate and tech entrepreneur, said:

"I'm looking to not have this machine just buried in a closet somewhere," adding he wants to take his collection—which he estimates includes over 800 coin-operated machines and countless other smaller games, trade magazines and original art—and build out a permanent museum.
