XP: Moving Backgrounds

http://www.youtube.com/watch?v=JutBmmtcOlY

This is an example of what I am trying to do. Look at the background behind him duing the battle. Is there any way to simulate this sort of drag effect in RMXP? A better question: Is there any way to do moving backgrounds in XP at all?? Help would be very much appreciated.

Continue to watch until about 2 minutes an thirty seconds have passed. can you see the Menu System here? How would I do that?

Moving backgrounds would need many frames and a subsystem in the update method during the battle, that changes the background all the time. Since battlebacks are not really small pics, I think this would lag a lot.
About the menu: Well, all you need is a CMS.

Hmm...So it's basically impossible to emulate the battlebacks perfectly...and the Cms thing is something I coulld look into.

About a CMS. Ask Blizzard. He has experience with those.

But he's busy with his project...should I?

He can say no if he is too busy

All right, I will PM him...when I am awake, and am able to properly explain what it is I want.
