Vertical scrolling was painful to implement. I've posted some of it in the Kiwi's Tale thread (the one in the blitz forum) but the gist of is:

- use the copper to split /wrap the bitmap at edges
- use clipblit twice when the Bob needs to be blitted on both sides of the divide (otherwise, regular blit is fine)

I'll think about doing a proper demo sometime
