- By hardware-tricks most people mean calling/reffering to absolute adresses
- in the rom. If the rom is changed or the locations of the rom-routines are
- shuffled around, things will stop working. Therefore hardware-coding can
- hardly be called legal.
-
- By the way, turning off the C64's border re-drawing, wich is a few bytes of
- code, can hardly be called forcing the machine to do things it shouldn't.
- Making the Amiga sound like it has more than four voices, or fast moving HAM-
- games are much more of that theme.
