[A83] Re: something to talk about
> Crashman's routine handles more than simple scrolling. A simple shifting routine will only work for single pixel horizontal scrolling. His method handles full eight way scrolling. No matter how much you optimize a conventional routine, you cannot get decent speed out of it. Redrawing the entire screen using shift tables is the only reasonable method (that anyone has come up with). Other nice features such as animated map tiles are essentially "free".
1. I know I'm badly informed, but what do you mean by this shift table
method?
2. Is LCD handling on the 86 just as annoying as on the 83 and the like,
or it costs less time (compared to 50k cycles for a complete screen)?
