I bought the Wii --> Scart RGB from Game last week. When I asked for it (it wasn't on show, it was upstairs) the guy asked if I wanted "the one with a plug on each end, or the one with a plug on one end, and all the phono connectors on the other ?".
Apparently they had both, I am assuming he meant the component. As my TV only has Scart, I got that. This was in Game, Wrexham.
