• Scroller_XUnlimited is based on an article which long time ago appeared on the German Mag "Amiga Special". I don't recall the name of the author but I think his initials were M. L.

• All the other algorithms were invented by myself with some help of a program which allows searching bitmaps in CHIP RAM to check for example out how the bitmap of games like Turrican look like in memory.

• Many thanks go to Alexander Weber for helping with the documentation.
