Use this on my Gamecube (PAL), Super Nintendo (PAL) and SFC. All work great. I wasn't sure whether this would work on my SNES mini which was modified for RGB, but yes! it also works too! And you can tell quality because the cable is made from custom connectors with RGC logos engraved, so you know that these are not off the shell parts or crappy 3D printed parts. The real deal!

I bought this for my PAL SNES and PAL GameCube and the results are simply awesome! Super handy having one cable for both systems (my N64 doesn't output RGB but I don't doubt that it would work on that too)

If I ever want great quality cables I always know where to look - Retro Gaming Cables is the best!
