      As far as i know:
      The Supergun outputs RGB video… so there are separate lines for the red, green and blue color channel. It may be possible, that the Supergun is defective and sends an out of spec or garbage signal with to much voltage only over the red line, while the green and blue signals are fine. So in the best case the signal on the red color channel line is ignored be the OSSC or Framemeister (= blueish/greenish picture)… in the worst case some components are damaged on the OSSC or Framemeister (= blueish/greenish/no picture).

      A damaged component on the OSSC would explain the blueish/greenish picture with your Xbox after using the defective Supergun. But as ‘marqs’ said: it does not explain, why the picture with your Hyper NeoGeo 64 is perfectly fine…

        Sorry to derail the conversation for a bit, but which game is the Xbox screenshot from? It’s not a game I remember having played, yet the character looks familiar and it’s driving me crazy not figuring it out (I probably just recognize her from other screenshots of the same game.) 🤔

        Edit: I found it is from the intro FMV to Dino Crisis 3.

          Could it be that the display has issues with certain resolutions/refresh rates? That would be the only plausibly explanation I can think of on how 2 boards via Boardmaster and Xbox via component have color issues while NeoGeo 64 through the same supergun and PC via VGA display normally. It’s also worth mentioning Framemeister preserves framelock as long as source refresh rate is somewhat close to 60Hz. I’d do some investigation with different superguns & displays before replacing any parts.
