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 PAL GameCubes do. 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), see here.

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.
