Japan NTSC Sega Saturn
Saturn RGB SCART cable
SCART converter box
component cables (from amazon)
Sony 27" WEGA CRT NTSC
I have an adapter that allows me to output composite from the Saturn SCART cable. When I connect this way, orange looks very orange, so I know that the Saturn as well as the RGB cable are putting out a proper orange color in the signal. So that means that the converter box may not be putting out the proper colors. Or I'm seeing what I'm supposed to see.
Since I don't know much about RGB, my question is this: does RBG output a differnt color palette than what I see through composite or S-video etc.? Or should I be seeing a solid orange color through RGB just as I would with composite?
Japan and Europe both use the same SCART connector for RGB, but they are not completely pin compatible. It is possible that you are using a cable/device that is designed with EU SCART in mind with a Saturn that needs Japan RGB 21 connector. It has been years since I've looked at the wiring but perhaps that drives your issue.
