The idea of horizontal velocity is to increase (or decrease) joystick
reading rate. A bit confusing, yet!? When I move joystick right, I can
increase the number of joystick reading per scanline, and when I move
joystick left, I can decrease the number of joystick reading per scanline.

I'm not sure I understand these terms. I think 2 Sprites should be enough,
but I don't know if it should be the best choice. Any suggestions are
welcome.
