It isn't *that* hard to avoid... Think of it as an extra > twist to the puzzle ;-) I'm not sure what you mean by "block" - could that be char (position) - I think - or ??? As one cpu clock cycle equals 8 pixels on the vertical beam position - it is quite imposiible to time a store instruction within the 8 sub pixels that a block/char consists of... And when the whole point with the demo is to shift the colors to make vertical color splits on the screen - I see no workaround... :-) You can see screenshot examples here (no self-promotion intended) https://csdb.dk/release/?id=9232 https://csdb.dk/release/?id=26184 /Uffe /Uffe -- Sent from: http://cbm-hackers.2304266.n4.nabble.com/Received on 2021-01-08 02:00:03
