You might not know this, but Nintendo actually hired Sony to create a new console and CD-based storage solution for them many years ago... before Ninty stabbed them in the back and partnered with Phillips at the eleventh hour. Sony then took their ideas and turned it into the original PlayStation, but there must have been some prototypes knocking around back when the two companies were working together.
Apparently one of these prototypes has now been found.
The images, which broke on Reddit (currently private to protest the firing of a popular Reddit employee) and summarily started doing the rounds, show a rough and ready console that's capable of accepting both SNES cartridge and CD-based games.
It certainly looks like a dev kit in all its angular glory, and has yellowed realistically on its lower half, though some doubt remains on whether this might be a hoax. The top half is pristine (3D printed, perhaps?), but it appears genuine enough to be worth running.
Even if it's not legitimate, it's still a fun reminder of how the two companies nearly formed an unstoppable alliance... and how Nintendo inadvertently created one of their biggest rivals!
