Nintendo teamed up with Sony to develop a CD-ROM add-on to the SNES in the early ’90s. The add-on never came to fruition and Sony eventually ended up releasing the PlayStation, which used the then-new CD-ROM technology. Little was known about the details behind the SNES CD-ROM add-on, until now. Steve Lin recently posted images of Nintendo’s internal documents on his Twitter which showcase the details of what the add-on was supposed to be like. The documents illustrate various details, including how the add-on would have worked with the SNES, and its technical specifications. Hit the jump to see some of the documents!
