[Stickied] UPDATE: The Equestria Gaming Arcade Still Needs Help!

Update 5/23/2017: We've decided to go with the ol' "throw the old ones through waifu2x and use the ones that actually look okay" trick. That's actually turned out surprisingly well, all things considered, but we're not quite out of the woods yet! There's still a small handful of games whose thumbnails simply couldn't be upscaled without looking like total garbage, so those are still Fonzie-fied for the time being.
If you can get a decent screencap of the games whose thumbnails are still missing, have it cropped to somewhere between 200x200 and 320x320 and send it our way, you'd be the raddest person who ever lived. Thanks, and check out the revised list below!
