Trip2018 Posted June 19, 2021 Share Posted June 19, 2021 I haven't been making anything in the past couple of years for the 2600 but this idea has been nagging me for a while. I'm probably blind and this has been asked many times before, but basically, would it be possible to "race the beam" turning playfield bits on/off mid drawing to "double" the playfeild resolution? Or even simpler, simulate a sub pixel offset for smoother scrolling? I'm sure there are a few drawbacks to this like with reading pf bits directly, but it's worth a try Quote Link to comment https://forums.atariage.com/topic/322026-playfield-resolution-doubling-with-dpc/ Share on other sites More sharing options...

Trip2018 Posted June 19, 2021 Author Share Posted June 19, 2021 Naw I'm talking about horizontal resolution. Could we simulate, a smaller pixel width by turning pf pixel bits on/off mid drawing. Or is the hardware too slow? Quote Link to comment https://forums.atariage.com/topic/322026-playfield-resolution-doubling-with-dpc/#findComment-4847246 Share on other sites More sharing options...

Here's a related post talking about each playfield pixel being 4 color clocks wide: atariage.com/forums/topic/169128-what-is-the-atari-2600-screen-resolution/?do=findComment&comment=2091765 Quote Link to comment https://forums.atariage.com/topic/322026-playfield-resolution-doubling-with-dpc/#findComment-4847284 Share on other sites More sharing options...
+Karl G Posted June 19, 2021 Share Posted June 19, 2021 Batari Basic handles the display routine "under the hood", so "racing the beam" isn't really an option. Even with assembly, however, there's not a way to draw a partial PF pixel in the way that you describe. They are always going to be 4 color clocks in width, starting at the same offsets. 1 Quote Link to comment https://forums.atariage.com/topic/322026-playfield-resolution-doubling-with-dpc/#findComment-4847297 Share on other sites More sharing options...
