[Coco] Coco game engine demo

[jmlaw at iprimus.com.au]

It’s such a neat effect, and really no different to updating a single page, just you restore the last page and update the the next page instead of the same page.

Obviously a few more variables to keep track of what page you’re on and the current scroll rate, but if you doing page flipping already for a 2 pixel scroll, it’s not much more to implement 4 pages and well worth it I think.

To be able to scroll at 1,2,3,4,5,6,7,8 pixel steps etc depending on joystick position makes the scrolling and sprite animations much smoother. If you want to add this to your scrolling engine Richard, feel free. 

I’d love to see any game use this 

Steve, I think I’d seen your game mentioned in Rainbow but I’ve not played it. Was it a CoCoFest special?  If you are able to make your games available again sometime, I’d really like to see it.
