GroovyBee Posted May 31, 2015 Share Posted May 31, 2015 Can you make a mock of what you want to achieve? You have to bend your ideas, get creative and make compromises in order to fit your ideas into the meagre resources available. Quote Link to comment Share on other sites More sharing options...
xxx Posted May 31, 2015 Author Share Posted May 31, 2015 a bit like this? http://www.randomterrain.com/atari-2600-memories-tutorial-andrew-davie-11.html kernel_11.bin Quote Link to comment Share on other sites More sharing options...

xxx Posted May 31, 2015 Author Share Posted May 31, 2015 ive seen this as a demo. http://www.atari2600homebrew.com/digital-photo-album.html Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted May 31, 2015 Share Posted May 31, 2015 So you want a parrot picture? I guess not . Post a mock of what you want for your game/demo and then its much easier for people to make better suggestions. Quote Link to comment Share on other sites More sharing options...
xxx Posted May 31, 2015 Author Share Posted May 31, 2015 (edited) any picture will do. why not that one? i want an 8 pixel line bitmap Edited May 31, 2015 by xxx Quote Link to comment Share on other sites More sharing options...
xxx Posted May 31, 2015 Author Share Posted May 31, 2015 can sprites not be wider than 8 pixels? Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted May 31, 2015 Share Posted May 31, 2015 any picture will do. why not that one? i want an 8 pixel line bitmap Actually it won't. The best results will be achieved by tailoring the solution to the image you want on the screen. If you want more than the 2600 can deliver then you have to change what you want to do. Thats a normal part of the development process on these old machines. 1 Quote Link to comment Share on other sites More sharing options...
xxx Posted May 31, 2015 Author Share Posted May 31, 2015 ok. lets use this image Quote Link to comment Share on other sites More sharing options...
+SpiceWare Posted May 31, 2015 Share Posted May 31, 2015 The demo you linked to only uses 48 pixels across, not full screen, plus it uses flicker - each scanline is Red, Green or Blue and which color appears on which scanline (as well as the pattern of pixels) changes for every frame. It's done using Andrew Davie's Chronocolour routines. Use the search feature to look for more info on chronocolour. Trying to use the 2600 to display a full-screen multicolor image is like trying to use a screwdriver to pound in a nail. Sure you might get it to do something, but the results won't be pretty and will require a lot of effort on your part. Quote Link to comment Share on other sites More sharing options...

xxx Posted May 31, 2015 Author Share Posted May 31, 2015 48 pixels wide is a start. Quote Link to comment Share on other sites More sharing options...
Omegamatrix Posted May 31, 2015 Share Posted May 31, 2015 You know, I think somebody did something with that parrot picture Yeah, it was in the programming challenge thread. Quote Link to comment Share on other sites More sharing options...
+SpiceWare Posted May 31, 2015 Share Posted May 31, 2015 A Programming CHALLENGE, posted by Andrew Davie back in 2013. Lots of discussion on how to do it and a few examples. This reply by Omegamatrix draws the best image w/out using flicker. Source is included. It features 3 unique colors per scanline, 18 quad-pixels across, Quote Link to comment Share on other sites More sharing options...
