Why Your SNES Turned Yellow
If, back in the day, you ever wondered why your old Super Nintendo tended to discolor, your curiosity will now be sated. Via Ars Technica's Opposable Thumbs blog, an article on the Vintage Computing and Gaming site which explains the mysteries of plastic discoloration. From the article: "Since ... different batches of plastics had ... different aging results ... then there must have been a difference of additives between them. Perhaps in one of the production runs of plastic, they didn't get the catalyst or flame retardant mixture quite right and more residues were left over in the top half's plastic batch, thus causing it to degrade more rapidly over time. And by the time Nintendo produced the later runs of Super Nintendos, they had perfected the manufacturing process of their plastic, meaning that those later models aren't as susceptible to oxidation as the earlier models are."
Now if someone can explain why my Megadrive turned yellow?!
Spelling mistakes, grammatical errors, and stupid comments are intentional.
I guess that explains why my old monitors turned that ugly yellow... thanks.
If I've said it once, I've said it 1000 times, wash your hands after eating cheetos.
They did this too. -Fortunately- I painted mine and now it looks worse than it would have done should it have turned yellow :)
EWW!
It's turned all boxy and the buttons have turned purple too!
In Soviet Russia, plastic urinates on you!
Well my SNES is still gray. You would think this would be more prevalent. Ive got a lot of old plastic stuff, some faded, but none change colors.

You get the same with a huge number of materials; the problem is that the additives don't complement each other well: if you want flame retardant, you get something that oxidises with light more easily. If you want super-white white, then the damn thing melts if vaguely near a flame. I had to do some research on this about a year ago - it's even worse with fabrics. I think there may be more expensive materials that balance the two better - but then you add expense to the case. You can have superwhite and then top it off with a layer of something tough and clear, but then you need to bind the two materials and create extra manufacturing cost from having thinner slices and having to put them together. Or - like the current trend - you can pick a colour that's not such a pain in the ass.

If you have a "happy mac" (128/512/SE/Classic), the same thing happens to them, including the keyboard and mouse.

The SNES turning yellow was a huge technological leap for Nintendo.
My old NES just decomposed - I kept it in the attic for a couple of years, but the day i went up there to get it, there was nothing nothing left but a pile of dirt. The only thing unaffected by the decay was the golden finish on my Zelda 2 cartridge.
I'm told that the wii has nuclear decay, now that's progress.
I noticed a while back that (amongst other things) my Atari 800XL (not my photo) had yellowed badly, but that the 1050 disk drive (again, not mine), which was part of the same bundle and appeared to use the same beige plastic still looked "as new". I doubt varying exposure to daylight could account for all of this.
Interestingly, my year-old keyboard has a white plastic case and keys. However, plastics that appear identical to the naked eye, aren't always so similar when viewed with IR.

Don't eat yellow SNES.
"My snes turned a yellowish huge"
Wait, it change color and got bigger too? I don't think that's tobacco you're smoking...
This is a silly, silly, little article. What's next? Why last years' newspaper turned yellow, Why my bananas turned black or Why the copper roof turned green.
