You need a clean copy of the rest of the FFX soundtrack? Ok i'll upload it sometime in the next day or so.
Arche - There's no soundtrack available for in-game music. It's just the movie scenes. Not sure if they plan on releasing one at a later date, but as of right now, Movie scenes is it.
Rubedo - princeofdarknez has the XS1 soundtrack on his FTP you can grab the song from. Are you talking about Xenosaga Episode II - Beyond good and evil or the video game by Ubi-soft? If it's Xenosaga then yes the trailer song is a bonus song on the second disc of the Episode II soundtrack.
Erased - Kuja's theme and FFX Opening Theme. I'll get them to you in the next couple of days.
