Does composite to vga adapter have a crappier pic than s-video to vga?

Ok so here is what I'm wondering I have seen lots of vga boxes for ps2, but what I want to know if what signal goes into the box affects what goes out to the monitor on the other end? So if I use one box taht feeds a s-video signal into the vga box will the image on the pc look anybetter than a vga box that feeds a composite signal into the vga box??

Yes, definately.  The weakest link in TV style video systems is whatever the worst format used in the system is.

You do know that you can get RGB out of a PS2, right?  It'll be interlaced (15kHz) and won't display on most PC monitors, but arcade monitors and european TVs with RGB SCART inputs will display it just fine.  That'll look better than just about anything else.

Yeah in your case a box is a bad idea.  If I'm not mistaken you can get a set of cables for this sort of thing and hack it to your arcade monitor.

If you can't get RGBS to sync on the monitor in question, then you may want to try component (YPbPr) and a component to VGA transcoder "box".  It is a little better than the s-video type but probably not as good as a line doubler.  I am using this solution for my consoles until I learn to make centering adjustments on my RGBs circuits, and they look almost the same on my CRT; RGBS being a little sharper

only problem with that box from lik sang is that only progressive scan games will work with it....... or so I have read? Will scart image to a auto multisync 27" billabs monitor show a full screen or will there be overscan of any kind? thanks for any info

Arcade monitors almost always have adjustable geometry, so you can over or underscan them as much as you want.  If the Lik-Sang box only works with progressive PS2 games (of where there are sadly very few), then it's nothing more than some wires and a sync separator (you can buy an LM/EL1881 for $cheap and build it yourself, in other words).  You can get ncie sync off the composite video output in standard res, but not progressive mode.  Getting RGB in progressive mode out of the PS2 is a bit harder since its sync on green is fubar'd (as in there appears to be no real sync at all, but there's often enough info for a monitor to reconstruct everything from the blanking pulses).

The way I did it was to chop the end of a SCART cable and use that.  I would have used a SCART socket, but those are remarkably hard to buy in the USA.  The quality is equal to that of a real arcade output (in fact, some arcades these days are nothing more than console hardware thrown in a box).
