I have noticed on certain games that, especially letters and certain types of sprites (bullets), have what looks like scan lines running through them. This can give certain items on screen a fuzzy/blurred look. I play 99% shmups on my ps2 and it can have a big impact on certain games. I can't make a screen cap of my ps2 to show unfortunately. The effect is easily noticeable when regional warnings display at the start of games too eg. DoDonPachi. Btw I'm playing mostly NTSC games via SM/cogswap. Any ideas?
