I have Pokemon Ruby and Pokemon Pearl, and I decided to migrate Pokemon from Ruby to Pearl again. I've done it once already, but that was a long time ago.
So, I put Ruby in the GB Game Pak slot, and the "Migrate From Ruby" thing came up in the menu. It asked me if I wanted to migrate Pokemon from Ruby, and told me to make the DS clock match the game's, and then it said "Pokemon cannot be made to migrate for 24 hours" but didn't show me the menu to choose my Pokemon to migrate.
Discuss.
