I came across this effect in the main menu of Konami's Double Dribble. How this works is rather simple:
- The
plane scroll mode
is set toline scroll
(VDP register $0B) - The
hscroll table
is pre-filled with numbers that represent a sinus style offset for each line. - The plane is then moved vertically by writing an incremented value to the
vscroll table
, while the graphics are tiled across the plane's dimension.
