Making a screen scroll up or down as an effect?

I’m currently tweaking the screen shake code to scroll a screen upwards to give a “take off” effect. It’s not ideal, as I can’t start my graphics below the bottom screen barrier or have the scroll end above the top screen barrier. But it does the job.

however, having it scroll (or roll) downwards is a bit glitchier. It sort of jumps backwards a couple of lines before continuing to scroll to the bottom.

anyone know a good way to do this?

(For use in a cutscene where something falls, or something flys upward)
