team magmas hideout is where you go down from the cable car, east of lavaridge. aqua is a surf north away from lilycove or mossdeep, i forgot sorry.
There is a master ball in the Team Magma's hideout in Pokémon Ruby Sapphire, and Emerald. Look in the Hoenn region for the Team Magma's base of operations.
In Emerald, an old lady in Mt. Pyre will give you Magma Emblem. After you got it, go to Judged Pass. If you bring the Magma Emblem, the Magma Hideout will appear in Judged Pass.
