ed's right, the changes are minor. They do stuff like this in Japan all the time. Games get re-released with like a new ending FMV and the stuff that got added to the American version, which isn't enough to make a new game out of. They do this mainly for hardcore fans who'll buy any and every thing with FF stamped on it multiple times, and the dorks who wine about how America gets all the cool stuff. It's like the difference between an original release of a movie, and a director's cut (actually, they did this with Resident Evil: Director's Cut too).
