Can you trade between LeafGreen and Colo. even w/out the National Dex? Because Colo came before FRLG, it makes sense that they may not have thought of this when programming Colosseum.
Actually, I just tried it. On the TV screen, it said that the trading machine on the other side is undergoing adjustments or something like that. Which sux. I need to trade a Clefairy over to Emerald, the ONLY Pokemon my Emerald version currently has no acsess to *traded away last Clefable before completing dex*
Really? That's odd, I could have sworn Colosseum could trade with FR/LG (EDIT: before obtaining the National Dex, I mean)...maybe it was Colosseum and Emerald.
