I just finished Pokeom Colosseum, and wanted to trade Pokemon to my LeafGreen game, and then to Pokemon Pearl.
However, when I try to trade, I get this message: "The GBA POKEMON Game Pak's trading system is not ready. You need to progress further in your GBA POKEMON Game."
So exactly how far do I need to progress? I've done the Elite Four and I've gotten the National Dex from Prof. Oak. What more do I need to do?
Been searching for the answer all over the 'net, but have found it nowhere. Please help?
