Can I try? A GC game (Paper Mario): A Wii game (Club Penguin): A random PC game (Nintendo Nightmare): Are they compressed well? Can I improve them with something? What do you guys think?

Just add PNGs and we'll compare.

Didn't notice this topic until now, so my comment is a little late, but: I noticed a major difference in the GC 007 game screenshot, in the more compressed jpeg the overall clarity is down a lot, and I can hardly see the crosshair, it was almost blended away entirely in the compression. I could not see any such major problems with the other screenshots, but I did notice an overall blurring in all of them, some less than others.

I'm wondering if the optimizer is blurring the images for better compression. When you compress more with JPEG you don't usually get more blurriness, you just get more visible artifacts. Blurring the image a bit before compressing can allow more compression with less artifacts, but only works with photographs, not drawings or pixel art / older computer graphics.

All the pics in the OP were before the proper method was figured out, and can be skipped down to http://tasvideos.org/forum/viewtopic.php?p=397166#397166
