Might as well ask here. I have a US SNES that's hooked up with composite. My PAL SNES is hooked up with RGB obviously, but from what I know the US SNES doesn't support this, but it does support S-video. My TV only supports RGB and has no S-video input. I tried an old SCART adapter that also has S-video input, and I do get a sharp image, but no color. Is there any way to get color or am I stuck having to buy a new TV?
The US SNES does support RGB through SCART. You'll need a different SCART cable though. One that is made for PAL Gamecubes will work with NTSC SNES units.
As for the S-Video->SCART adapter, are you sure you don't have an extra channel on your TV for S-Video signals? On my Trinitron I don't have an S-video input, but I can use a scart adapter and set the channel to AV2s rather than just AV2 to get color with S-video. This only works with one of the scart inputs on the TV though.
