Just received a new RGB SCART cable for playing SNES on my CRT.
I've only ever played with s-video but my new CRT doesn't support it so had to upgrade to RGB.
s-video is very good but RGB gives me brighter more vibrant colours.
Got it from retrogamingcables. I went for the universal one that works with NTSC and PAL in case I get an SFC in the future. My current SNES is modded for region and 50/60Hz selection.
Really nice build quality. A wee bit more expensive but you get what you pay for. The image is gorgeous. Would post a picture but my camera doesn't pick the CRT picture up very well.
