Finding Ultima Weapon and Bahamut

On the southwest corner of the world map there is some hidden ruins that has a place to land the Ragnarok. (This is where Bahamut can be found). The trick to get Bahamut is simple. Once inside the ruins walk the the center where the computer is. (Every step you walk is a random battle). Once there you'll hear Bahamut growl and you'll get two options, so answer the first one. You'll fight a red dragon. After that you'll be given another two options and answer the first one again. The second one will transport you outside the dungeon. You'll fight another dragon and after that you'll be given two more options and a hidden 3rd option. (Note: Sound familiar? The Shinra Mansion letter when finding Vincent in FF7?). Of course answer the third and you will fight Bahamut.
