You have to obtain it in a mystery event
use the mystery box if you have it and then you'll have the ticket
I think you can't catch Ho-oh in Pokemon Emerald. But, you can find it in Nintendo event, or use GameShark...
Genesect is an Event pokemon. You have to get it via Mystery Gift
after completing everything possible and getting all the stars on you trainer card go to mossdeep and fly to the moon. There you will find Deoxys and Jirachi.
You cannot find a deoxys normally(during game play). but you can get it during an event. first you have to get a mystery gift. if you do not have the mystery gift, it is explained on the Pokemon website. there is no deoxys event currently going on.
It is an event-only Pokemon so you need to wait for a Mystery Gift event or you could use the Action Replay.
you get mystery gift it automatically after you get the pokedex in the game. try going to serebii.net to find out what pokemon event is going on through mystery gift.
Ask someone else not me!
You find it on Naval Rock, which you can only access through an event.
It's possible if you have a gameshark or there's a Nintendo event only
I'm not all that sure about how you get it.(problabe an event)But if you get to the island you climb a hill and belive it or not YOU WILL FIND A MEW IN EMERALD!!!!
