I hoped Glenn would see the message and give a yell, since he was the last to host The Dig (afaict), but nothing yet. His AtariAge.com PM mailbox is also full, though he's posted relatively recently. Any status update on Glenn? If he's the only fellow using mos6507 as a handle, it looks like there's a recent interest in gardening. ;^) Ruffin Bailey From sa666666 at gmail.com Tue Jul 28 06:40:56 2009 From: sa666666 at gmail.com (Stephen Anthony) Date: Tue, 28 Jul 2009 09:10:56 -0230 Subject: [stella] How to get stretched graphics in Meltdown? Message-ID: <200907280910.56400.sa666666@gmail.com> I've been reading up on this, and it seems to happen if you do two successive writes to NUSIZx with different values. First you write a 4, which sets two wide copies. Immediately afterwards, you write a 5, which sets the player to double size. I'd like to know two things: 1) Why does this work? 2) How many cycles can pass before it doesn't work? Or more specifically, if I were trying to detect this effect to properly emulate it in Stella, how might I go about doing it? Perhaps if a subsequent NUSIZx write occurs within X clocks of the last one??

He has also posted a little demo program to this list a couple years ago with some dragons in it. What's happening is basically that there are four possible copies of a player in a line. Sometime during the five pixel offset before each copy the TIA checks NUSIZ to decide on whether this copy is supposed to be drawn or not. Once this decission has been made you can change NUSIZ to something else and the copy will still be drawn. For each pixel the tia outputs it checks NUSIZ to see if it's supposed to advance the player graphics output or not. So if you change NUSIZ from quad width to single width in the middle of a quad with player pixel, you should be able to 'shrink' the pixel. IIRC we never did enough tests to find out where exactly during the five pixel offset for a player the decission to draw it is made. Also we never tested all possible combinations to find out what effects changing the pixel size has during the display of the player. And to make things worse, I think during my tests with Andrew's program I encoutered some occasional extra offsets for a copy, which even differed between the different versions of the TIA. So while it might be prety easy to get Meltown to work, finding out what's going on exactly to emulate this effect correctly would require a whole lot more testing.

Yeah, but the AA forums have too much noise for an old man like me to keep up with, and it's not like programming on Mac OS 8 & 9 are bringing in thousands of hits either. ;^) Nice to see Stella emulator updates and a good question every month or three on the list. Re: The Dig -- It was my understanding that you had taken its contents and put it into a database. Do you have an archive of the original static Dig or a backup of your db? I remember finding The Dig especially useful when I was playing around last, and would enjoy using it were I ever to dust off the cobwebs and start back up. I'd be more than happy to wade through files and get it running on my webspace, even if I'm the only schmoe using it.

It's been a while, but I'm 99.44% sure that The Dig had a number of decent demos that had been written on the list, often sort of proof of concept demos that could be used quickly by n00bs. I'm thinking of the Alpha and Beta (http://atari2600.org/pipermail/stella/2002-January/009589.html) demos that Manuel put together. The original posts that he pulled together in those demos had decent comments at times (even though Manuel says, "and don't rely on any comment!"), and were useful. Seems The Dig had a number more that weren't in Alpha and Beta. I'd missed the Mini Dig and will link there, though. The full games are a little intimidating for a beginner, but it's very useful. Thanks. (I Freudian typed "debugger" for "beginner" there; need sleep) Perhaps I should recut Andrew's "2600 Programming for newbies" (http://www.atariage.com/forums/index.php?act=Attach&type=post&id=9470) and Kirk's 2600 101 (http://www.alienbill.com/2600/101/) to pull some of the simple source out of those.

The pro-forum people always said, "Nothing's stopping you from staying on the mailing list and letting the people who don't understand email use forums". But as I expected based on my Maxim experience, there are more browser-wielding functional illiterates interested in Atari than there are people who are capable of writing an email, so it was only a matter of time before the critical mass shifted. And in another few years or decades, when Albert gets tired of running AtariAge, they'll all be on some other forum going, "Did anyone ever grab a backup of AtariAge?" Luckily, most Linux-related groups are still lists because most of us have a superiority complex, so I have plenty to read and do. But I do miss being part of the Atari community sometimes, like when I heard someone had run with Ballblazer about six months after the fact. > Re: The Dig -- It was my understanding that you had taken its contents > and put it into a database. Do you have an archive of the original > static Dig or a backup of your db? I remember finding The Dig I have a mirror of The Dig circa 2004-05-19. It's about 160MB (split evenly between www.homebrewgames.net and www.atari2600.com directories, so I assume there's a lot of redundancy) if anyone feels like hosting it. If not, I'll probably throw it on my own site once it's moved to my company's new colo, assuming my backup doesn't die before then. It's not nicely extracted or databased, so there are a lot of ZIP files with names like "index.html?action=attachment.download&attachment_id=234" and I'd probably have to write a script to mimic the behavior of the original. But hopefully it would be navigable on the web. Rob
