CastleMania Games has just received stock of the HD15-2-SCART adapter. This device has two modes: The RGBs mode is designed to prevent higher voltage sync from dsub connectors for passing through to SCART devices. This mode is perfect for things like MiSTer I/O and Direct Video, or Analogue DAC to SCART. The second mode uses an XNOR passive sync combiner to convert RGBHV signals to RGBs – Perfect for feeding a “VGA” signal like the Dreamcast’s into something like a RetroTINK 5x.

Think of the HD15-2-SCART as both a sync combiner and connector adapter: It routes the RGB signal from an HD-15 (VGA-style) connector and a 3.5mm audio jack to a SCART head, with a choice of sync passthrough or combining. The RGB signals are completely untouched, therefore no lag could possibly be added. Check the video below for more explanation and use cases.
