I am looking for a high quality VGA to scart cable to connect a V9990 to the scart port of a OSSC.

Thank you!

What makes the cable high quality?
I made one a few months ago and could make another one easily since I bought spare connectors and enough cable. Only thing is that the connectors are your regular units. No gold pins or flashy/fancy logos. The video output is great from v9990 to lcd. So yeah, if you want one, you can get one, but I don't have € 25,- connectors

Thank you for the reply and offer. I will maybe take you up on that :-)

First, I have decided to try to build one my self in the weekend. I have a lot of old VGA and scart cables lying around.

Did you use a special "recipe" for the cable? I am a bit unsure if I should use 100 ohm resistors in the cable?

Thank you!

I don't have any resistor in my cable.
Here's the cable:

VGA connector	SCART connector

1		5 and 9 (make a wire bridge there)
2 		13
3		15
4		11
5		7
6		16
7		20

Not really rocket science

I have also build one my self. I used an old VGA cable, cut of one plug and soldered a SCART connector on it.
I used a VGA cable for 3 reasons:

Cable Quality and shielding is better then a SCART cable.
It's easier to get a SCART plug then a VGA plug
Also a SCART plug is easier to solder then a VGA plug.

Wait a second... All this time, even while typing it myself, I completely overlooked this VGA thing while I was revering to a DB9 connector. That's the connector on a Sunrise gfx9000.
If you got something else with another pinout/connector, forget everything I said

I somehow doubt resistors are necessary... surely the V9990 outputs a proper RGB signal already?

Still looking for a good VGA to scart cable for connecting my Tecnobytes PowerGraph Lite:

http://www.tecnobytes.com.br/p/v9990-powergraph-light.html

Been using a cable ment for the MINT from Lotharek: https://lotharek.pl/productdetail.php?id=171 but that gives me massive problems with noise when I use a Scart switcher before my OSSC. I have tried two different scart switches (both a Hydra Mini and a Hama S100 but the problem is the same so the problem is with the cable - somehow.

Thank you :-)
