Reddit reviews Cinpel S-Video Cable for Nintendo 64 N64

Then buy one of these, because an S-video cable for SNES/N64/GC is almost impossible to find in stores without the standard yellow plug also attached, and when they have the yellow plug attached they are more than likely to be connected wrong.

People have already correctly advised you to get an analog to VGA converter box, but I'd like to chime in and suggest you get a Nintendo S-Video cable as well. S video looks much better than composite, and the better signal you feed into the VGA box, the better the output will be.

here is the cable i used. works fine and has indistinguishable picture quality from my official one.

These generics don't have the yellow either:

Will the ebay one you sent be better?

This cable is just as good or better than any Monster brand S-Video cable.

But honestly, if you paid the dough for an XRGB-Mini Framemeister you should really RGB mod your N64. It's not a lot extra to put out, and it's a huge difference. The colors on S-Video are still very dull and blurred together compared to RGB. My main N64 is an RGB-modded console plugged into a Framemeister, and comparing it with S-Video is a joke.
