Sledge: I hadn't even considered a scrolling game in Blitz before being intrigued by this thread. I wasn't even going to post, due to a subconciouss belief that trying the method I described would end up messier and slower than really necessary, due both to Blitz' intrinsic problems doing anything out of the ordainary with image buffers and the extra head-work needed to grok the basic method of hardware scrolling (and then applying it in software).
Still, I had to put the idea out there, even if just so someone (like you) could definitively slap it down with good reasoning ;)
