Yep, does anyone know how I can change the starting position of a background or make it not repeat vertically?
I'm having trouble sometimes with the BG's repeating, there is a mountain in half of the level then it just gets cut

I have not been able to get a background to be truly static so that it doesn't repeat...Late for work here, but look in the backgrounds posts and there is an explanation of scroll speeds. You can slow the scroll so that it won't repeat as soon.

Some backgrounds are taller than others as well. Look at the original you are editing first.

I don't know if you can change background starting position. But I have been able to start them differently by putting them higher or lower in the 512x512 background grid. I think entrance height within view does the start position of the background as well. Try making a view and then using camera scroll stop sprites if needed.

LOL, why didn't I look here http://nsmbhd.net/thread.php?id=31 ooops
