There is none. In ruby and emerald, however, it is on the Jagged pass.
The Magma Base doesn't exist in Sapphire Version, but the team Aqua's Base is located outside of Lilycove City.
Er isn't a Team Magma base in Emerald. In Ruby is er one by the city with the big market, in Sapphire is there an Aqua base.
No, you cannot be a member of Team Aqua / Team Magma in Sapphire.
go to magma hide out
There is no magma amulet in ruby. The location in which team magma's hideout is actually is the place where team aqua's hideout is in sapphire and emerald (i think you confused sapphire with emerald)
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.
You do not see Groudon in Sapphire. The reason is because Team Magma is you ally and the story is about stopping the world from raining for an eternity. You can see it, however, if your friend has one and his secret base transfers to yours.
there is no underwater galactic hideout, the closest hideout you would get to underwater is the aqua/magma base in ruby and sapphire

its on rought 128 in sappire/team oqua, ruby/team magma, and not shoure what criminals in emerald
Team Magma and Team Aqua aren't even featured in Pokemon Diamond and Pearl. If you are looking for Team Galactic bases, you will find those throughout the region in Cities such as Veilstone and others. If you want Team Magma's and Team Aqua's base in Ruby and Sapphire, it is just off the beachead in Lilycove city.
