i had this version of final fantasy X
http://www.covergalaxy.com/ps2/Final%20Fantasy%20X%20International%20JAP%20COVER.jpg
it had bonus boss fights, Penance Boss fight (hardest boss ever, EVER!!) , Bonus Yuna's Story cutscenes (Ala before FFX-2) , and also have the option to select the "International" Sphere Grid, which is a different more harder but more rewarding sphere grid
among those there was the option to select english or japanese subs (i don't remember about dubs though)
Square enix have been making international versions since VII (when they re-released it on PC)
