Not at the moment, and I don't think it'll be possible, certainly not at
single-scanline scrolling resolution.  I'm planning to fake the scrolling,
by using enemy graphics to display "stationary" but scrolling objects,
both in and outside the river.  Like River Raid's fuel tanks and buildings
on the river banks - those give a definite sense of movement even in the
bright-green areas where the playfield doesn't move.

Also, I need the playfield where it is to cover up the edges of the
screen.  The player's bullets wrap around from side to side, and also the
kernel actually has no way to turn off enemy bullets; when a bullet
shouldn't be drawn it gets positioned at the left edge of the screen
instead.  The river banks hide all that ugliness; CTRLPF is set for the
playfield priority to be highest.
