u cant
It's free, just go in and download it.
To get an Arceus in Soulsilver or Heartgold, you needed to download it at an event, otherwise you would have to use codes or trade from another game.
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.
Two options. One, watch Bulbanews (Google Search it) for a future Nintendo event where you can download Arceus onto your game. Two, you can get an Action Replay.
You have to go to the Pokemon event to get the flute to catch arceus. You could also download the cheats onto your R4, but that's 10 times harder then finding games that work!
A time ago was it for a week or something but you can , hack or trading with a friend . O , yes if you have a card where you can download on ds and two times a ds , you can download here something where you can get Arceus and all other Pokémon : http://www.4shared.com/file/70901372/6785f473/Pokemon_Weird_version_2.html?s=1
You can, but I don't have the codes. You can go to supercheats.com to download action replay codes so you can catch them.
you need to go to the next movie and download the azure flute and go to the spear pillar it will be at level 80
There is not an arceus trophy, and arceus was created after brawl, so arceus is not in brawl
There was a Arceus Download at Toys R Us during April which has already past and be available next year. Also on Pokemon Platinum, Pearl, and Diamond you can find near the Spear Pillars.
