Great Hierophant Posted February 29, 2004 Share Posted February 29, 2004 Certain Atari games use the artifaced mode of the C/GTIA, but I am not sure what the proper colors should be. On the Atari800Win emulator, the primary colors seem to be Purple and Green, but it also has other options. I read somewhere that the colors may be dependent on the system, not necessarily the graphics co-processor. Quote Link to comment Share on other sites More sharing options...
Goochman Posted February 29, 2004 Share Posted February 29, 2004 The 800 series was brown/blue and the XL/XE series was more blue/green, however the XL series had the artifacting reveresed where on the 800 the combination would yield blue on the XL it would yield brown/green. Some games asked which OS to compensate. Quote Link to comment Share on other sites More sharing options...
ZylonBane Posted March 1, 2004 Share Posted March 1, 2004 Certain Atari games use the artifaced mode of the C/GTIA There's no such thing as the artifacting mode. The colors you get in Graphics 0 and 8 are an accidental side-effect. Hence the name, "artifact". Quote Link to comment Share on other sites More sharing options...
Nukey Shay Posted March 1, 2004 Share Posted March 1, 2004 By clever placement of pixels, it's also possible to get a couple other colors...like yellow and a pinkish-white or bluish-white...I think by odd+even+gap+even and even+odd+gap+odd. Something like that. Quote Link to comment Share on other sites More sharing options...

Something like that. Yeah - Im not sure how these were affected by the OS change though. I think I was able to get 5 colors in gr 8 once - white, blue, brown, yellow and purple Quote Link to comment Share on other sites More sharing options...
Nukey Shay Posted March 1, 2004 Share Posted March 1, 2004 Uh huh...that has the advantage over multicolor modes by allowing more highly-detailed images when using strings of at least 3 horizontal pixels. Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted March 1, 2004 Share Posted March 1, 2004 another method i am working on is transparency paper put on the monitor to gain 16,7 mio colours.... but at the moment i am stucked with static pictures only and i am missing a good painting tool for that method... sad that this is not working for moving gfx but grafic adventures definitly benefit from that... i call that "real mode" just kidding....

Hmmmmmm - So why does the XL os present the artifcating effect differently than the 800 os? The XL series shifts the video which changes the offset I thought.
