      OK, despite all the praise, for the longest time I was apprehensive about getting a RetroTINK 5X because of its lack of a VGA input. I know 480p SCART cables exist for Dreamcast, but the ones I’ve been able to test all produce an image that is noticeably darker than a straight VGA signal. Plus I understand that a small number of games don’t support RGB, only composite and S-video. That’s why I’ve always used the official Sega VGA box.

      Anyways, recently I found found a website called Retro Upgrades. I had never heard of it, apparently they sell the GBS scalers. But they had another product that appealed exactly to what I was looking for. They have a transcoder called the VGA2SCART Sync Converter.

      The product description says: “Accurate picture – does not produce a dim image like some other VGA to SCART devices.”

      Mine arrived today. And I can confirm that there’s no brightness loss. 😀

        Those are very useful not only for RetroTINK but also OSSC for any source where you’d get 240p or 480i out via a d-sub15 cable.

        I wonder if the Dreamcast SCART cables are wired such a way because it’s supposed to have some brightness loss, as with Megadrive/Genesis 2 SCART cables (to save money, components were not placed inside the console). Have you verified using a test pattern that the VGA picture is, in fact, not over bright?

          I have no means of loading the 240p Test Suite on my Dreamcast. But I took screenshots of my recordings and measured the RGB levels in PhotoShop. I did not find any appreciable difference in brightness. In any case, on the 480p SCART cables that I’ve used with the Dreamcast, you can tell the brightness has been significantly diminished just by eyeballing it. As I demonstrated in the other thread: https://videogameperfection.com/forums/topic/retrotink-5x-or-ossc-pro-buy-now-or-wait/#post-48399

            Sorry didn’t notice this, you can run 240p test suite on an unmodified Dreamcast simply by burning it to a CD.
