I'm thinking about it but I really need a few more colours than this allows.

I've tried this and the speed is not to bad at all. The main problem with this
though is that the floor moves much to fast. Is there a way that I could
smooth it out a bit? Is it possible to blit in fractions of pixels like when
displayscrolling or is there another way. At the moment the first line moves
at a rate of one pixel the second at two pixels and so on, but like I have said this
is much to fast. Any ideas?
Best wishes,
Jason.
