This is not the way to catch Deoxys in Pokemon Emerald. You need an Action Replay or GameShark in order to catch Deoxys.
I think if you have all badges, and beat the elite four he should obey you. I'm sorry, but you'll have to be an excellent Pokemon hacker if you want Deoxys and Mew to obey you.
To get the rocket to launch 100 times fast in Pokemon Emerald you will need to use a cheat device or wait 100 weeks. It should be noted that nothing special will happen when the rocket launch counter reaches 100. The 100th rocket launch was a popular source of rumors along with the white rock at the station.
In Veilstone city. There should be 4 meteorites on the east side of town. If done correctly it should say Touching the meteorite balanced out the attributes of a certain Pokemon. That Pokemon is Deoxys.
You should definitely get Pokémon Emerald.
There should be a move deleter in Pokemon Emerald, try to find this person and you should be able to delete your moves.
you really should get emerald cause Pokemon ruby and Sapphire are separate and emerald is those 2 put together so instead of getting ruby and getting groudon just get emerald and you can get groudon and kyroge and newer Pokemon
You should evolve sunkern when you are in need of a strong grass type, and when you have a spare sun stone on hand. In Pokemon Ruby, Sapphire, and Emerald, you can get a sun stone in the Rocket Institution in Mossdeep City.
