What about my s-video consoles? Can I use RGB converters and SCART cords to improve these: SNES, N64, Sega Saturn, Sega Dreamcast, PSOne
SNES is RGB native, N64 can be modified for RGB, Saturn is RGB native, Dreamcast you can do either RGB or VGA (VGA is the better option) and PSOne is RGB native.
You just have to get the cables for each. A seller who sells all those cables is currently away, but I'll link them once she lists them again.
And since they're all SCART, you need a switch box, I'll see if I can find the one I have.
