According to Jim Christy, the US and NTSC SNES have a 'DC offset', which is basically extra voltage, on the RGB lines. You can filter this out with one 220uf capacitor on each of the RGB lines (+ towards console, - towards display). PAL SNES systems do not need these caps, but may require some 47 ohm resistors in their place in order to get the video contrast down to the correct level. PAL GameCubes need the caps, NTSC GameCubes don't output RGB through this connector.

For reference, here's the pinout I use to connect all my systems to my monitors. A single common pinout means I don't need a seperate monitor cable for each system.

For info on adding RGB to some Nintendo 64 systems, see here.

To add RGB to a SNES2 (SNESjr), http://www..

Here is the pinout for the GameCube Digital AV port.

PAL Users Note:

A PAL SNES outputs +12v on pin 3, not composite sync. This is for a SCART TV to automatically detect RGB input. Thanks to Mark K. for this info.
