[...] Anyway I apologize if I'm not considering artifacts when I show my graphic examples. No apologies needed. I don't expect everybody to hobby the same way I do, and ignoring composite artifacting is a perfectly valid thing to do. On your topic of a post-composite world, my own view is a display that's incapable of composite artifacting is deficient for retro consoles. Tower Toppler and Rikki+Vikki use composite artifacting for color. I used composite artifacting in the Petscii Instruction screens for a splash of color. Even when composite artifacting is accidental and ugly, I still want it displayed that way on my screen, because that's how it truly would have been seen back in the day. For me, bypassing artifacting feels like an artificial enhancement, along the same lines as using a pixel art scaling algorithm in an emulator. 3 Quote Link to comment https://forums.atariage.com/topic/349547-320-mode-colours-question/page/5/#findComment-5310820 Share on other sites More sharing options...

Okay, thank you, that clears up a misconception I had nicely.

To be clearer, I was not referring to games for which the developers have voluntarily chosen to use artifacts, obviously these games should be played with artifacts if conditions allow it. I was referring to today's scenario, since today we have the ability to view the 7800 via S-Video, component, RGB, VGA, HDMI, emulation and even RF + excellent comb filter, so today a developer can decide which result and/or public prefers to privilege. As I was saying before, back in the day some Atari 8-bit (and the C64) were equipped with S-Video and the 7800 PAL had some sort of RGB (and also the Sega Master System) so when I draw graphics in 320 mode without considering artifacts I don't feel like I'm getting an artificial result, but that's just my opinion. I like to imagine an alternative scenario, where the 7800 achieved sales success and then got a hardware upgrade with S-Video. I am enthusiastic about every new software and hardware resource, for example every new bankswitching scheme, and in the same way I don't consider a 7800 with S-Video to be an artificial system, but again that's just my opinion.

I had thought that pixel pairs were only defined based on 160 pixel coordinates. For 320 and composite artifacting, no. There are color restrictions on 320 color modes that do get impacted by the 160 mode grid. (easier to think of it as 320 mode pixel pairs) 320A does have a pixel pair quirk, but it manifests with transparent pixels paired with lit pixels showing up as background color instead of transparent. It's usually a very subtle effect, though you can amplify it if you try hard. (e.g. use a bright background register color, and paint background tiles dark) 4 Quote Link to comment https://forums.atariage.com/topic/349547-320-mode-colours-question/page/5/#findComment-5310958 Share on other sites More sharing options...
RevEng Posted September 7, 2023 Share Posted September 7, 2023 The other thing about composite artifacting, is it happens in the 160 resolution too, just less strongly. From the 7800 color documentation wiki entry, here's an example of artifacting colors from two different composite displays... ...from left to right, the first two colors are produced by alternating light and dark pixels. The second (striped) set of colors are produced by alternating pairs of light and dark pixels. (i.e. 160 resolution). This is part of the reason why graphics seem a bit more sterile when displayed on an emulator with lcd vs console with composite device. 3 Quote Link to comment https://forums.atariage.com/topic/349547-320-mode-colours-question/page/5/#findComment-5310977 Share on other sites More sharing options...
+saxmeister Posted March 9 Share Posted March 9 One of the things that I have found helps me is using GIMP and configuring the grid in a 2x1 configuration. That way I can always view the pairs of pixels and assign the colors. First, show the grid. The, configure the grid. Then, set the grid size to be Horizontal: 2, Vertical: 1 3 Quote Link to comment https://forums.atariage.com/topic/349547-320-mode-colours-question/page/5/#findComment-5426235 Share on other sites More sharing options...
