yeah I got sick of fuzzy genesis composite video quality. Then I found out that both my genesis consoles have the chip that doesn't generate s-video. And my tv doesn't have rgb. So I bought the cheapest rgb to s-video converter I could find

then I built a case for it

did a bit of fun wiring

and here's the difference

so I think I paid around 50$ for all the parts and crap needed to built this device. But the great part is I didn't have to do any internal modification to my genesis. I think it's worth the money, and I suggest it to people like me who're happy with s-video.
*edit* time for a couple of updates (I don't think anybody cares but whatever).
of course we need to see how nice this little thing makes sonic look

And I figured "....why have this thing hard wired into my genesis only when I could have it work for any system?"
so it's now been scartatized, mark II lol

so now I just buy a scart cable for whatever system I desire that doesn't internally generate s-video (master system, neo geo) And don't have to do anymore wiring. Only thing is on most systems I have to rewire the scart composite video directly into the sync pin on the console. Not that hard. Not like I'm going to miss composite video anyway.
