Thanks to everyone for the replies. Here I learn a lot of beautiful things. I did not know that one could use sprites in text mode. Anyway what I was looking for I seem to have found it in the examples in gr. 7 mentioned above. I admit those examples are very advanced, I will try to understand them.

Hi Jac! Thank you very much indeed. I thought that showing a picture in assembly was more difficult however is quite easy. As soon as possible I will try GRAFX2 program.

Hello to everybody. To move hardware sprite is very easy but you can use a single color for the sprite. I'm looking for routines to move software sprite with pre-calculated data (possibly in gr. 15). I could write the routines by myself but I am a beginner and I'm sure I would do not-optimized code. Probably many people have faced the problem with good results; could someone pass me the routines? I suppose you use double buffering. Is it a good idea to use software sprite on an Atari 8 bit machine or performance on it are disappointing? Thank you.

Thank you very much. Your example was just what I needed. Are there programs for Windows to edit the image in the example?

Hello to everybody. In my programs written in assembly I would like to import images. Are there tools to facilitate this topic? Are there examples that show how to configure in assembly the color palette to show an image file included in the sources? Is there a standard for the file format of the images on atari 8 bit? Thank you.

Could you post some videos on youtube for those who haven't dragoncart. Thank you.

:-(

A very exciting project! It would be very nice to see the architecture ip65 running in Atari 8-bit Graphical User Interface program. I encourage the author of this post to complete the work that is not within everyone's reach. Is there an emulator that emulates a dragoncart to try ip65? Thank you.

Thank you very much. The code snippet is very interesting. I did not understand what is the function _Ciov documentation for these? jmp (vdslst) jmp (vvblki) jmp (vimirq)

Hi to everybody. How can I use the 16kb of ram under the rom os in a 64k machine? Are there examples? Thank you

Thank you very much.

To show an image when the program is not yet fully loaded I need to combine 2 executables? The Atari works as a first executable shows the image while the second executable is loading. What I do not know is how to combine the two programs into one.

Hello. how do I show a picture while the program is loading? Yoomp shows a bouncing ball while the program is loading; is it complicated to do such thing? Thanks

hi, DLI is probably the easiest method to show more than 4 colors on the screen but I have always a maximum of 4 colors for each scan line. There are games that show more than 4 colors for each scan line, in this case what technique do they use ? What is a "display kernel"? Is there documentation about it? I found this Teaser Trailer on youtube: is it a joke or really a standard XL / XE machine can show so many colors?

Hello to everybody. I am a beginner and I'd like to learn how to program the Atari 8-bit. Is there anyone so kind that can explain how to show more than 4 colors in graphics 15 (160X192) in assembly language? Thank you.
