Great quiz, but...
...Allow a Sony fan to set the record straight for you. The Playstation had precious little to do with Philips. Nintendo was actually working with the Sony corporation in 1988 to develop the "Nintendo Playstation." Sony offered a lot of technical assistance in the development of what was going to be a revolutionary CD Rom-based addition to the Super Nintendo.
However, in 1991, Nintendo made the mistake of stabbing Sony in the back by developing a new CD gaming system with Philips. Not ones to take this lying down, Sony decided to push forward using the original Playstation design they had created with Nintendo. Nintendo wasn't using it, after all.
In fact, if you open up an old Super Nintendo, you will notice Sony parts inside of it, such as the sound system. Nintendo should take full responsiblity for their current console failures, for turning their backs on a business partner.
Great quiz, though. Full of memories.
