I want to know the answer to the following question:
Which companies did Nintendo try to get to make a CD add-on for the SNES?
All the background I'm provided with is that "During the SNES's life, Nintendo contracted with two different companies to develop a CD-ROM-based peripheral for the console to compete with Sega's CD-ROM based addon, Mega-CD.". Is that enough to answer the question?
Answer: no
