Non scrolling backgrounds

[Dr.Eggman]

I'm wondering if there is a way that you can make a background static as you move along the scene... So as you walk through the level, the background doesn't move.
Is it even possible?

Yes. Pick either the SMB3 pipes background or the SMB2 underground background and edit it to be 800 in width and 600 in height. That way it will not scroll at all.

I tried this, but can it be made non-scrolling in both x and y directions instead of just in x.
This wouldn't have been so much a problem if the background didn't look so weird when I move down in the y axis of levels.
Any ideas for this?
