you ned to go to www.codejunkies.com
there is none
If you have Arceus, then all you have to do is give it one of the plates that can be collected around Sinnoh, for example, the Splash Plate. Then the Arceus will change its type.
i do not think there is a code try codejunkies.com if it is not there i do not know where to find it...
No, you do not need all of the plates to catch Arceus. You can use the plates to change Arceus' type, though. Arceus is only available by event (which has long since passed). You can also use an AR (action replay) to hack the game and get an Arceus, all without plates.
You get them through out the game
You catch an Arceus with an event/ cheat code and make him hold it. The different plated changes his type.
See the following link for a complete listing of Plates and their locations: http://bulbapedia.bulbagarden.net/wiki/Plates
To put it simple, no. Any mart. Holding L & R then talk to the man in the green, he'll give it to you! :) Also, once you have Arceus, he can change colors. :) (Put different plates on him) Go here: http://www.serebii.net/diamondpearl/arceus.shtml to see all colors with plates. (Shiny and non-shiny)
No, but it helps if you do catch it. Arceus has a special ability called Multitype. When it holds a plate, it transforms into that plates preferable type. (E.g. Stone Plate = Rock Type, Zap Plate = Electric type). it is not proven when you get all of the plates arceus will appear, but what you really need the azure flute.
There is no Unknown Plate for Arceus, there are only plates for each type.
no you must have plates ex: thunder plate or sky plate
