If you mean the Atari 2600, you can make your own Atari 2600 games using batari Basic:

Do you have any previous programming experience?

You can write games for the Atari 2600 in either batari basic or assembly language.

There is a good tutorial for assembly language here to help you get started:

What kind of games are you interested in writing?

I'm running the board mobile skin here, but there should be a code box that you can enter the code in so it doesn't lose its formatting.

Have a look at Nick Bensemas "How To Draw a Playfield" document. That should help you out.

Updating sprite copies is very machine-cycle dependant. The cycle count for the scanline needs to be exact (based on sprite positioning) as each storing instruction ends. I'd suggest looking at a 6-sprite display kernel demo for starters, since your above example contains some pretty fundamental errors (like how lda Score4,Y is immediately overwritten by lda Score5,Y before it had a chance to be stored anywhere).

And please post examples as file attachments instead of text pasted to the post.

No foul, actually. It's just a suggestion, since a downloadable attachment makes it easier to get feedback on...and add comments regarding exactly where a routine is going awry.

Not to mention, make the thread easier to read followup posts and deal with the current issue(s) ;)


Anyway...based on your initial sprite position of 50, it would go something like this example. I also altered the positioning subroutine to work with any sprite (instead of using seperate ones), and included a commented-out example for using digits that can change (instead of the hard-coded "012345" always being displayed).
