Trying to get the best video quality with my consoles (and other problems)

[ApolloBoy]

Looking up more about SCART, it looks like it would cost a lot and probably isn't worth the trouble. S-Video seems like the way to go. Is S-Video the second best unmodded video for the PS1/Saturn/Genesis/SNES/Master System?

You can get S-video unmodded out of the SNES, PS1 and Saturn, but you need to mod your Genesis and SMS for S-video. Getting SCART cables might be a little pricey but the picture quality through RGB is absolutely incredible. I use RGB for a lot of my systems and I haven't regretted it one bit. It is definitely worth the trouble.
