1st you need to trade an Arceus from pearl, diamond or platinum (or wait for an event).(you can also get arceus in i think Mt. Mortar, then continue with these steps)Once you get Arceus go to the 'Ruins of alph' and go to the scientists house.A man will run out and bump into you, he tells you about strange things that are happening in the ruins.He takes you to the ruins and you teleport to the Sinjoh ruins, then you get to decide if you want:LV1 Palkia, LV1 Dialga or LV1 Giratina.You can only get it with an Event Arceus. You go to the Ruins of Alph with Arceus following you. A man will come and will take you into the ruins, and you will disappear and reappear in Sinjoh Ruins. Cynthia will talk to you about the place and will tell you to put all your Pokemon (Except Arceus) in the PC. Then you can create either Dialga, Palkia or Giratina.you cant. heartgold and soulsilver is just a remake of the original gold and silver and giritina didnt exist then. besides, you dont need giritina to complete THAT pokedex.YES you can get giratina on soul silver and heart gold you need to go to the ruins of alph and but you need a ARCEUS to get it and you can choose giratina,palkia or dialga but they are all level 1
You cant. The item is a key item and you cant use it more than once
Once you give the doll to the copycat girl.When you come out Steven will talk to you about Latias.Use your poke'gear to find her.She will be roaming Kanto.
You can only obtain Arceus through a Nintendo hosted event. But, the event might be distributed through WiFi download so, everyone with WiFi can enjoy the best Pokemon of all time. (Once you get the event Arceus is supposed to be able to be caught in the "Hall of Origin" which appears after you download the event.
