-
- My current scroll system allows any colours, (no Dual Playfield),
- Bobs to be anywhere, icons to be displayed OVER bobs, background
- icons to be animated (redrawing them each frame), scrolling in any
- direction.

- No.

- Well, basically I'll have to use two screens, both double buffered I
- believe and will use up far too much memory!
