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?

my formating didnt work it was fine when I pastedit in :-(

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.

[Nukey Shay]

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.

[babz]

thx fo r the help!! still lots to learnsorry for the copypasted code ill attach files nxt time!! promise!!!! ;-D

k'thanx!!!!

[Nukey Shay]

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).
