Take a look at Asphyxias Demo Tutotial. It has both fire and scrolling.http://www.ice-digga.com/programming/asphyxia.html
well it depends on what language you code in. if you program in c i would recomend abe's demoschool cause that has some new effects. (denthors effects are standard in sucking little mcga mode demos that never should have been released;)
