I'd agree with Prophecy's first post, this is a lazy remix.
All that has been done is loop a theme FF9 and looped a drum beat in the back, with the odd sound.
There is no change in the bass (wait, can I even hear a bass?!?!), there is no change in the main melody, there is the odd electronic fill in the drums.
The artist obviously does not have much of a knowledge of music, as there is many, many moments in the main theme that just scream for a chord change, yet nothing happens.
