vertically scrolling the playfield
|

==================================
|
|

|
Vertically scrolling the playfield is the easiest thing to do on the amiga ;-)
|
|
|
|
Just offset the bitplane pointer addresses by the number of lines you want to scroll, and make sure you have enough bitplane data.
|
|
|
|
Set the scroll speed by changing ```SCROLL_SPEED``` in [constants.i](constants.i)
|
