SNES - Playstation prototype found after 25 years

Okay, I wasn't completely off course, but I did read on it this morning.

Heat is a factor in the yellowing process (sunlight included) but it is more a sort of "rust" due to some of the flame retardant chemicals and poor mixing processes at the time. Explains why I never saw much of it personally, my stuff always stayed in the dark, or maybe I just happen to get the good ones.

Still say, in the end the "prototype" flag will justify almost anything though, which would make it next to impossible to prove fake.
