Is there a fast and easy way to tell if a Pokemon Ranger game has transferred a Manaphy egg already?

Question

I might be able to get a used copy from a store but I'd want to check first that I can actually get the egg because I don't actually want the game just the two Pokemon for my collection.

Answer 1

You have to enter the password for it in "Ranger Net." If the password doesn't work it was probably already transfered. Here is the steps to get the mission for the egg including the password.
