The Nintendo Play Station was a video game console created as a collaboration between Nintendo and Sony, which was planned as a two-part release. The system was initially going to be released as a hardware add-on for the Super Nintendo Entertainment System, under the name Super NES CD-ROM System (or referred to by the shorthand SNES-CD or Super Disc), which would add a disc drive to the SNES hardware and allow the machine to support compact disc based games. The second iteration, under the name Play Station, would be custom hardware developed by Sony from the ground up that would function as a standalone hybrid console.
After several years of back and forth, the project was canned, and Nintendo decided to work alongside Sony's primary competitor, Phillips, instead- a collaboration that would eventually lead to Phillips gaining the ability to use Nintendo's franchises to create a sleight of games for its CD-i platform, such as Hotel Mario and Zelda: The Wand of Gamelon. While a large number of executives in Sony lacked interest in video game development, Nintendo's decision to drop Sony and work with Phillips instead has been referenced in the past as one of the factors that lead to Sony deciding to enter the market with the Sony Playstation.
While the console was never properly developed, approximately 200 prototype units based on Super Nintendo hardware were produced. After the negotiations fell apart, the prototypes were ordered destroyed. In 2015 however, one of those prototypes were uncovered; having apparently been left behind by former Sony Interactive Entertainment CEO Ólafur Jóhann Ólafsson. The forgotten prototype was then taken by Terry Diebold, won in a bid among other Advanta assets after their 2009 bankruptcy. The device was left in storage and forgotten about until Dan Diebold, Terry's son, discovered the unit in 2015- sharing images of the unit on Reddit, and invited Benjamin Heckendorn to do a teardown of the hardware in order to safely ensure its ability to run, a process that was eventually completed in 2016.
In July 2016, an independent team released Super Boss Gaiden, a beat-em up action game in which you play as a corporate executive enraged at the public obtaining a piece of the SNES Playstation hardware. The game remains the only publicly released Nintendo Playstation game, though a download for a SNES port to play in emulators was released as well.
