How do I change to special dresspheres in FFX-2?

romanticdeath is right.. you need to change into every dressphere programmed on that character’s grid during battle, then the R1 option will come up. but unlike what they said.. in order to get the “Good Ending,” you need to get above 70% (so I’ve heard) and need to press X while on the Farplane in the final scenes. then you’ll get a common ending with a good ending after the credits. a perfect ending is finishing with a 100%, pressing X on the farplane in the final scenes, and you get a common ending then credits, then the good ending and finally the perfect ending. I just beat it with a 94% but cheated and looked up the perfect ending online… it’s all worth getting! :)

Dude, that one’s easy. It doesn’t give enough detail on the game for to tell, and you only want to do it in harder battles so that you can leve all your other Dress Spheres up, but you’ve got to switch the EVERY Dress Sphere on the Sphere Grid. If that doesn’t work, try doing it with all the characters. I haven’t played in over a year, so I don’t remember the exact details. (To get the good ending you have to learn every skill on every Dress Sphere and complete the game at 100%)
