Hello.
 I am creating a arcade game now. I was wondering if there was any
simple and efficient algorithm for graphics to make the WHOLE screen
scroll, sans your character. Sorta like super Mario Bros. I was
thinkng of XORing the background, then redrawing it at the new pos..
but jeez. I can only imagine how slow that will be. Ideas? I am
using Turbo Pascal.
							Thanks.
