One way is to trade with another emerald or you could trade your latias (or latios) to another emerald then restart the game and choose the opsite then catch it and trade back.
you go fly in the air and catch him with a net
You can fight in the battle tower, catch the three regis, search for latios/latias, or in emerald you can catch groudon and kyogre

all i know is how to get the regis and latios or latias.
