VRAM command object exiting Y = 0 how to do it?

So I have a problem. My engine scrolls up and down but the VRAM coordinates stay as they are so when a softsprite crosses the Y=0 boundary on screen the sprite gets copied on screen until Y=255 and then continues into the next page.

Logically this happens but are there any easy and fast solutions to make the command continue into Y = 0?
