I remember reading a while back about an option in the debug room which took you to an unfamiliar area of the north crate which appeared unfinished (As soon as I can dig out the exact info I'll post it up here) unfortunatly you're stuck in a wall, but it raises the question: Is there anything there, and are there any other similar areas?
I'm wondering, that since Jenova (the editor, not the monster
) can change your in-game location, maybe it's possible toa djust it so you are not stuck in the wall and see where it leads.
Afterall, if it IS unfinished, it may help us learn about how hey are made, since a work in progress might not be as hard to pull apart
