Type "How do you get the /three\ Regis?" because someone else has a long detailed answer on how to get to the underwater cave through to how to unlock the Regi doors so it isn't necessary for me to fully answer as he has. No worries :)
You can fight in the battle tower, catch the three regis, search for latios/latias, or in emerald you can catch groudon and kyogre
