Does anyone know of a website that shows you how to wire a vga output to a scart tv input (European standard)? This would allow me to use my tv instead of an arcade minitor using ArcadeOS and no additional hardware.

The VGA pinouts are here:

The Scart pinouts are here:

Be careful to output at 15kHz before you switch your TV on tho...

Take a look at http://www.tvtool.de (choose the English version if you don't understand German.
The TVtool utility looks to be pretty awesome by itself, with hotkeys for TV-OUT and back to VGA.
If you have an nVidia card w. the common TV chip (I forgot the name), then there is a detailed diagram of how to get pure RGB directly from your video card to SCART. The forum looks OK too, if a bit sparsely populated.
I just found the site yesterday, so I haven't tried any of it yet, but RGB directly to SCART has GOT to be nice! ;D

that website is rather good, very helpful. You must have a Chrontel tv-chip on your card for it to work tho, which is the actually crappiest of the tv-chips. Now just got to try and find a cheap geforce :)
I'm surprised no-ones posted this before, its very useful for an arcade machine, basically the same as an ArcadeVGA card.

Four people have posted about the TV-Tool hack these past copule of months alone. I posted about it like 6 months ago (and someone else brought it up long before that, but the Chrontel write-up wasn't up then). Problem is that no-one wants to try it, since you need to solder directly to surface mount components, and that's quite hard.
It is not even close to being as good as the ArcadeVGA. The TV out chipset only outputs at one resolution (512x288 if I remember right) and just scales other resolutions to fit, versus the ArcadeVGA that runs at multiple resolutions, as close to arcade as possible. If you're thinking about cost savings, remember to factor in that you need to register TV-Tool to use it more than breifly.
One more thing, you can do this mod to most TV-out chipsets that TV-Tool supports, it's just that the Chrontel chipset has a full writeup on how to do it.
