It seems the background doesn't scroll smoothly. Perhaps it's like scroll 1 frame, then pause 1 frame, scroll 1 frame, pause 1 frame etc. The quick level oveview scrolls nicely but ingame when running the background seems jumpy.
Is the original hardware like that too? - if not perhaps the scrollling could be smooth here too?
