Nintendo rechazó que PlayStation fuera un complemento de SNES
Back in the 80’s and early 90’s, Nintendo literally owned the console gaming market with its NES and SNES. At that time, Sony designed the original PlayStation as a simple peripheral for SNES but its partnership negotiations with Nintendo failed.
The SNES PlayStation was a simple add-on which allowed SNES to play CD media. Sony and Nintendo failed to reach an agreement to work on the peripheral together, so Sony decided to expand it into the full-fledged PlayStation console which ended up dethroning Nintendo.
Sony built a limited number of SNES PlayStation units and it was though that none of them has survived until an Assembler forum member named Dnldbld has shared a video showcasing one. Apparently, he acquired it from his father “who knew someone at Nintendo.”
