Basically, I'd have the entire bitmap in memory, and would blit a 200 pixel tall section of the bitmap to the screen each frame. The benefit that I can see to this is that the background can be hand drawn or scanned for great detail. However, is this really efficient, or would it be a ridiculous way to make a scroller? Also, is it possible to load single objects at a time from an Allegro data-file (so that I could have all the backgrounds in one data-file)? Well, that's about it. Thanks for your time and help:-) Jordan Ellis P.S. Allegro plays samples for me fine under Win95, but is silent under DOS. Why?? Thanks again 8-)
