In the midst of hunting down and obtaining Ultima, and the treasures on the northern part of the Great Crystal, when you open a Zodiac Gate, will it remain opened for good? I know that you have a choice of opening either "Gate I" or "Gate II" and only one at a time.
However, if I open Tauras Gate I first, can I go back and open Gate II for Tauras and the first one will still be opened? I'm just wondering if I have to go through the whole process of opening gates EACH AND EVERY time I go into the Great Crystal?
