Super NES CD-ROM
The Super NES CD-ROM (commonly abbreviated as SNES CD) was a proposed video game platform developed in the early 1990s by Nintendo via joint ventures with Sony and Philips intended to expand the functionality of the cartridge-based Super Nintendo Entertainment System (SNES) by adding support for compact discs (CDs). The collaborations with Sony and Philips resulted in two distinct projects that would support playback of CDs, one of which was an add-on device for the Super NES developed by Philips and another was a dedicated all-in-one unit developed by Sony under the name "PlayStation".
