Argh! Thanks for pointing out that open can of worms...
Using the Battlezone routine I had my assymetric playfield running with 2
sprites positioned where I wanted them and then this...
When I tried using the horizontal positioning routine to move the sprites in
accordance with joystick movement, the sprites jump approximately 1/4 of the
screen width (seemingly) with each frame... I am not certain if this is an
error in my (badly patched together) code or the natural result of not doing
the positioning during the kernel. I tried replacing the Battlezone hor-pos
routine with the Air Sea Battle method and got the same result...
I haven't worked on it too much yet, but I did try moving the sprites by
writing a value to HMPx and HMOVE in the joystick routine and got the sprite
to move smoothly... I might have to get my hands dirty if I want to move 3
enemy sprites and missiles this way... ;)
