Nope, no PAL console came with RGB scart (well French NES did), but SNES, N64, Gamecube and Wii have those for sale separate.
SNES cable was 3rd party only, but the other 3 have official ones as well.
And yes US composite cables work with PAL consoles aswell, but I think irvgotti452 wants RGB-scart, which the composite cables are not.
