Step 12: To get your Manaphy egg from Pokemon Ranger to Pokemon Diamond or Pearl you’ll need two DS systems. This will only work if the DS systems are set on the same language AND if both Pokemon Ranger and Pokemon Diamond or Pearl are the same version (meaning they have to be from the same region or country for the transfer to work!)
Step 13: Put Pokemon Ranger in DS system 1. Put Pokemon Diamond or Pearl in DS system 2.
Step 14: Turn on DS system 1 with Pokemon Ranger. Go to the “Check Egg” screen and click on it to go to your Manaphy Egg and touch it so you see a “Send” button. Touch the “Send” button.
Step 15: Turn on DS system 2 with Pokemon Diamond or Pearl. Press “Start” on the title screen and the game will tell you you’re picking up the signal from DS system 1. Then follow the on-screen instructions the game gives you.
Step 16: Eventually you’ll have to hit a “Transfer” button on Pokemon Ranger and the Manaphy Egg will be sent to Pokemon Diamond or Pearl.
Step 17: Now that you’re finished with the transfer, start Pokemon Diamond or Pearl game.
Step 18: Make sure you have an open slot (five or less Pokemon) in your party.
Step 19: Go into any PokeMart and talk to a man wearning green. He’ll then give you the Manaphy Egg!
