If you're looking for a place to host those tutorials, let me know. Every
now and again someone threatens to create a series of Atari 2600 tutorials,
but to date they haven't materialized. I know many people would greatly
appreciate them! :)

> Hiya...
> I was looking at Ruffin Bailey's Disassembly of missile.bin, trying
> to tweak some things and learn what's going on. One thing I don't
> understand...a couple times it has
> LDA # ;some postitive value
> STA HMM0;
>
> (once with Y instead of the Accumulator)
> when I replace that number with #00 , the missile is still moving to
> the right, seemingly at the same speed. What am I missing here?
> (a lot I imagine..."I assume the HMM0 commands are self-explanatory"
> my right big toenail! ;-)

> Eventually I'd like to make a series of tutorial demos of
> increasing complexity...one thing about "how to draw a playfield"
> is that I think most newbies are more anxious to get players and
> missiles going than the backdrops. So I'd try to start with a
> very clean moving missile, then maybe moving player, or moving
> a missle with the joystick, and maybe one or two up from there.
> Ultimately, it might be cool to work it up on a kiddy version of

> own game ideas, which are generally as simple or simpler than that.
