Nope.

No.
the is now way without using action replay or gameshark to get arceus because the Nintendo event for arceus hasn't even been released in japan!
no you cant
Official events are the only way to catch Arceus.
You can only get Arceus through Nintendo events if you don't want to use cheating devices.
you cannot catch him without events unless u use GTS ...Ok first off, you have to use events.... by CHEATING WITHOUT AR! To do so, look up the date of the time the had arceus up. Enter that date into your clock, then just Go back to mount coronet, Use Arzure Flute, and RUN UP TEH STAIRS! PAAAAAAAAAAAAAAAM! ARCEUS! try this at any DOWNLOAD STATION.
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.
it's a place to catch darkrai, shaymin and arceus
you need the azure flute i think you get it from mystery gift then go to a Nintendo event
you need to go to the Nintendo event and use the ranger for manaphy egg and the three:Shaymin, Arceus, Darkrai needs a Nintendo event and the others you have to catch or get from the gts.
