You could use an Action Replay (advised) or GameShark.
Do yourself a favor, use an Actiona Replay.
You could in the past get them on mystery gift, I don't think you can get them anymore.
the mystery gift works if you contact someone who has something like the old sea map or the aurora ticket. if you mix records with them, you also get the aurora ticket or whatever they have.
From what I have been told there isn't one. I could be wrong.
The only place I know you can get an aurora ticket is leaf/green and fire/red but I never fount anything about one in diamond and pearl so i say no even though i wish i could say yes but...................no sorry
you could travel to the country that is doing the event but it will be in a different language.
you really can not get deoxys in Pokemon ruby but you could get a gameshark and hack and i think you need aurora ticket
u can use the gameshark or you could have participated in the mystery gift event i can use the gameshark then what is the code?
You can find him on an island called Naval Rock, however you need to have the item Mystery Ticket which could only be obtained through an event that has already passed. The only way to get a Mystery Ticket now is to get one from someone else who happens to have one and is willing to part with it. That will be hard though. Not many people still have a Mystery Ticket and those that do may not want to part with it so easily.
the only way to get it is to trade it from Pokemon firered/leafgreen or u could go to the Nintendo event get from through mystery gift.
There might be but don't get your hopes up. No Information on this has been released in Japan or America.
No, ya can't get the Eon Ticket without an action replay(gameboy version) or hack, but their are some events you can find at Toys 'R' Us! You could go to Woolworth's but to bad the credit crunch shut it down.=Hope I helped! :)=
You Need Either A game shark or action replay, Or you could go to a Nintendo event if they even have them around anymore.
