Ecernosoft Posted August 20, 2022 Share Posted August 20, 2022 (edited) Hello! Now, I know about display lists. But without using DLI's to change the color, you can actually get 14 colors on screen! But how? 1. Use mono-mode to get 3 extra colors (2nd color (Mono) is same luma as Color2, but same hue as color 1, then you can get 2 more via artifacts) 2. Use Missile color = $D019 (C019 on 5200) for another color 3. Use multicolor sprites to get 2 more colors (Tri color = Color And tada, you get 15 colors! Of course you can get even more using DLI's, and only 5 colors are available on the Main (Lowres) part of your background, and the 3rd color for multicolor sprites is universal, as well as the color for all missiles. Oh I forgot- If you're lucky to have GTIA, (5200's always do I think) then you can get a whopping 32 more, using GTIA modes 9 and 11. This also can be used together to get APAC, where all 256 colors are available, making the 5200 the most colorful 8 bit. Of course, we can't forget the 7800 and it's 169 color mode. So without APAC, using DLI's to update the GTIA mode, you can get 46 colors. Unfortunately, the 7800 absolutley beats it because dispite the colors being more on 5200, with double the resolution, we get 27+ colors on 320C. (Artifacting only, using S-video and up, only 9 are present) Edited August 21, 2022 by Ecernosoft Forgot about OR features for tricolor Quote Link to comment Share on other sites More sharing options...
Ecernosoft Posted August 20, 2022 Author Share Posted August 20, 2022 (edited) I don't have demonstration of all 46, will make one soon and will use for the upcoming ICT5200! (It's Conner time 5200) I'll be using 15 color mode because GTIA modes are just too low-res to really use. (More than that because I will use DLI) Edited August 21, 2022 by Ecernosoft I forgot it's 15 Quote Link to comment Share on other sites More sharing options...
tebe Posted August 20, 2022 Share Posted August 20, 2022 use IRQ Quote Link to comment Share on other sites More sharing options...
Ecernosoft Posted August 20, 2022 Author Share Posted August 20, 2022 How do you trigger IRQ? I'm new to 2600 and even newer to 5200. Quote Link to comment Share on other sites More sharing options...
Rybags Posted August 21, 2022 Share Posted August 21, 2022 You get 23 colours in non GTIA modes using multicolour PM and mixing. Though palette is important since PM colour mixing is by ORing. Antic 4 = 5 base colours. PM on their own = 6 extra. PM multicolour with overlapped PF = 12 more The versatility of this method isn't very high in the real world but could be used to enhance a static image or with softsprites if not a lot of bigger moving objects are needed.

How do you get overlapped PF? How does this work? I'm new to 5200/8bit. (Also, I'll be saying 5200 for now on) Quote Link to comment Share on other sites More sharing options...
Ecernosoft Posted August 21, 2022 Author Share Posted August 21, 2022 I'd say, use 15 color mode for games. You get 2 multicolor sprites and a 6 color (8 on RF/Comp) playfeild, as well as another color for the missiles. It's what I'm going to use for ICT5200. people said the C64 was more colorful than the 8bit, they said "The 8bit can only do 9 while C64 can do 16" but then we showed them APAC mode and blew them away...

Ecernosoft Posted August 21, 2022 Author Share Posted August 21, 2022 BUT- I don't know how many people use S-video mods or RGB on their ataris so make it look good in 13 colors. Quote Link to comment Share on other sites More sharing options...
Rybags Posted August 21, 2022 Share Posted August 21, 2022 No overlapped PF, but with no priority bits selected you can get colour mixing with some PM/PF combinations. Quote Link to comment Share on other sites More sharing options...

Rybags Posted August 21, 2022 Share Posted August 21, 2022 I'm fairly sure I posted a picture and/or the creating program in another thread, but probably 10 years or longer ago. I'll look tomorrow to see if I can find it here or in my files. Quote Link to comment Share on other sites More sharing options...

tebe Posted August 21, 2022 Share Posted August 21, 2022 (edited) it's magic G2F does not display 'mode_plus.g2f' graphics correctly. mode_plus.7z Edited August 21, 2022 by tebe Quote Link to comment Share on other sites More sharing options...
Ecernosoft Posted August 21, 2022 Author Share Posted August 21, 2022 (edited) Why is it a .7z file?? My worst enemy..... Also, if it is a Disk file for Atari 8bit, it won't work on my emulator for some reason... Edit: How does this work?

rdefabri Posted August 23, 2022 Share Posted August 23, 2022 Correct me if I'm wrong - don't some of the GTIA modes ignore the collision registers for PM graphics? Quote Link to comment Share on other sites More sharing options...
Synthpopalooza Posted August 23, 2022 Share Posted August 23, 2022 Modes 9 and 11 do. I think mode 10 works ok, tho I am not sure. Quote Link to comment Share on other sites More sharing options...
