Replaced the FMVs' audio tracks, intro & credits, and a single tiny audio bank.
I also removed (not even relinked) everything regarding the German, French, Spanish and Italian languages, since they're massive bloat and touch to bothersome to deal with; the game probably won't boot if your PSP/Vita system language is set to one of those languages. If that bothers you too much, you can take the original ISO, replace the EN directory, and relink the regional files yourself.
