I guess I'll be the ass. You realize you're playing a PS2 game, right? Its far lower resolution than you probably remember and those sharp pixels are only going to be even worse if you're playing it stretched to fit a wide screen.
Here are pics of my actual PS2 running on an HD CRT thru Component video. Aside from your stretched screen, your emulation looks pretty authentic.
So the sharper you make it, the more jagged those pixels on Sora are going to be. If you want it to look
better different, you can find some video filter settings/plugins.

and the step labeled "Setting up the graphics" seems to help a bit in certain games.
