Ecernosoft Posted August 26, 2022 Share Posted August 26, 2022 (edited) Hello! I wanted to say that I’ve gone on a tangent. A tangent about Atari 7800 artifactjng, a way to get lots of colors in 320 modes! I’ve made some tests below for you to see.

Ecernosoft Posted August 26, 2022 Author Share Posted August 26, 2022 I want to make more versions of ICT on other platforms. A comparison between 6502 platforms, and when I learn Z80, those as well. 1 Quote Link to comment Share on other sites More sharing options...
Ecernosoft Posted August 26, 2022 Author Share Posted August 26, 2022 I'm going to make a test with grayscale to see the colors resulting from the test. If it's useful enough, I'll use it for CDL/ICT2. 1 Quote Link to comment Share on other sites More sharing options...

Ecernosoft Posted August 26, 2022 Author Share Posted August 26, 2022 (edited) So yes, you can get a full 16 colors using 320B. BUT it's better- There are 2 palletes, so you really get 32 colors. SMS quality, but at 320*224. Nice. (AND with a master pallete of 65,535 colors!!! Why? There's 256*256 colors, so with artifacts, you get 65.5 K unique colors! It's less because colors of the same hue don't artifact if they are too close luma-wise.) Edit for muddyfunster: This only demonstrates 4 because of the fact that one color alone isn't that interesting- You get a red version, and a green version, a pair of pixel-alternating version *Not very useful unless you have a line at least 5 pixels long with one blank in the middle, best for bricks) and the real color (2 pixels next to eachother) Edited August 26, 2022 by Ecernosoft 1 Quote Link to comment Share on other sites More sharing options...
Ecernosoft Posted August 26, 2022 Author Share Posted August 26, 2022 (edited) Again but with 11 colors. I noticed there are only 12 colors for some reason. (There should be 14, but 2 are invisible due to the 320B glitch) Here is the intended look: And here is the "Real look" Using my 2007 HDTV.

Ecernosoft Posted August 27, 2022 Author Share Posted August 27, 2022 (edited) Also a question: how many people have an s-video, or rub Atari 7800? Edited August 27, 2022 by Ecernosoft 1 Quote Link to comment Share on other sites More sharing options...
