SNES CD, I don't think so.
Rival companies NEC and Sega had taken the leap to CD based gaming, and Nintendo had no intentions of being left behind. They immediately partnered up with Sony to develop their CD based system. Sony went on to develop two units.
One was a 16-bit add-on for the Super Famicom / NES that sat underneath the system and allowed CD based gaming (SNES CD), and another as a stand-alone unit. Initially the agreement allowed Sony the ability to license CD based games for the system.
Nintendo was not willing to relinquish control over software licensing. They dropped Sony from the project, and approached Phillips to develop the add-on. Ken Kutaragi, the Sony researcher who had worked on the SNES PlayStation prototype and the sound chip for the SNES (Sony SPC700), did not want to give up the hard work put into the unit. He wanted to continue working on this project and so approached then Sony President Norio Ogha to develop the stand-alone console without Nintendo. The project continued, and the new Sony Computer Entertainment Division was formed.
Sony announced the console dubbed ‘Playstation’ at the Tokyo International Electronics Show in October 1991. The original Playstation concept would be able to play SNES games, as well as educational CD software.
Nintendo would try to re-negotiate with Sony in fear that they would drop support for the SuperNES sound chip, but the joint effort between the companies never saw the light of day. Ken Kutaragi went back to develop the Playstation from scratch making it a 32-bit console that was simple yet powerful, easy to program for, and cheap.
The new Sony Computer Entertainment division (SCE, SCEA, SCEE) began to use their company connections, and financial influence to persuade 160 3rd party licensees in North America alone and over 400 worldwide to develop for the newly designed Playstation
The Playstation (a.k.a PSX) was released shortly after the Sega Saturn on December 2nd 1994. The console was an immediate success selling over 100,000 units it’s first weekend. Developers found the Playstation simpler to develop for then it’s 32-bit rival Saturn. Sony then took it’s console abroad. The Sony Playstation immediately saw success in America in on September 9th 1995 driven by a strong advertising campaign, and a price $100 cheaper then Sega Saturn.
Europe saw releases a month later.
The PSX eventually claimed the number one videogame console sales position by beating out the Saturn, and even maintaining it’s position after the eventual release of Nintendo’s 64-bit console.
Even after the release of next generation systems, Sony saw an opportunity to make even more money out of the PSX. In 1999 Sony released the PSone.
This remodeled PSX console was made to the size of a portable CD Disk player. It was also both cheaper to by, and cheaper to produce.
LCD screens, battery packs, and vehicle power outlets also made the console somewhat portable. The PSX also has one of the largest libraries of software spanning 1000+ releases, and a wide assortment of accessories. Sony entered the videogame market with a formula for success..
