I've looked everywhere, and I keep getting the basic arranged version. Does anybody have the Piano Collections? The MP3, long version?
I really want the sheet music ):

trying gamingforce.org/forums - i think it's been posted there a while ago. did you search ichigo's forum?

So I'm guessing the one from eterniaforever.cjb.net is the basic arranged version?
I think that Sodasheetmusic.com has it under "extra sheet music." You can get the whole piano collections there.

All is on ffdream.com \o/
