I have an early version of the Oystron kernel with vertical scrolling.
I added it easiliy with a trick... a varying number of empty lines at the
beginning and the end of the picture:

frame n:

14 lines

picture (8 groups of 16 lines)

2 lines

frame n+1:

13 lines

picture (8x16 lines)

3 lines

But then there there's the problem of the objects that are half-in and
half-out of the screen...
