I'm forced to play Pre-PS3 games on my PS3 (for some God Mistaken reason, I didn't know you could play pre-PS3 games on a PS3) as my PS2 isn't working, and have been playing FFVII in order to write my walkthrough, and I've noticed that some of the sound effects have changed, the music is the same though. Has this happened to anyone else?

I'll give examples if you want, though only the sound effects, I dunno if I can describe sounds.
