Odd questions: Does anyone know how vertical scroll on a hardware level is implemented? For horizontal scrolling there's just is just a delay register. For vertical scrolling however, the only two ways I can think off are either having an adder (slow) or a separate counter (rather thank using the timing chin) to keep track of the vertical line. I couldn't relaly find anything in the documentation so any info wlecome! SG Posted By Superglob on 2021-11-14 00:00:35  Re: Vertical scroll Never mind. It looks like hte VIC2 implementation have a separate vertical counter that gets reset whenever the counter matches the vscroll register or if there's a bad-line. So That does away with an added although it comes at a cost of an addition counter. Back to top Reply to this topic Copyright © Plus/4 World Team, 2001-2024. Support Plus/4 World on Patreon
