An 8k demo for the Atari 2600.

Code and graphics by JAC!, sound by Jakub Husak.

This is my second Atari 2600 demo and it was a tough journey. Anybody who thinks retro coding is simple should give this machine a try.

I wanted to create a demo which is different from existing "typical VCS" demos which tend to use full screen effects at low resolutions without transitions but with HMOVE artifacts on the left side of the screen. I wanted to establish the classical logo/playfield/credits screen layout from the good old days of the cracktros and Amiga intros. Ironically, on VCS this is much harder than full screen effects :-) I wanted to create smooth effects which appear to be in multicolor hires resolution on a machine with 21 bits of screen RAM and 8+8+1+1+1 movable pixels. I also wanted as many effects as possible in 8k with a fast pace and proper transitions. The complete lack of interrupts makes the last one especially hard and expensive in terms of RAM and ROM usage.

I'm fucking proud of the result and I hope you like it a bit, too. See the .nfo for the technical details of the effects

- ISO Logo
- Floating and Falling Text Tiles
- Ribbon
- Plasma
- Twist
- Twirl
- Scroll


Thanks to:
- Grey/MSB for organizing Sillyventure and being so crazy as to start a VCS demo compo
... and for stretching the deadline
- Jakub Husak for the great tune
... and the player additions .. and keeping the deadline ... eventually :-)
- d-wilson for finding the article on "Why 2:16 minutes" again
... though the demo now takes 3:31 in the end. I had too many effecs :-)

Greetings and respect to:
Noice (cool ideas), Trilobit (cool stories), Tjoppen (cool execution) and all people at Sillyventure - one day I'll be there, too.

The download contains the 8k ROM together with Stella32/64 ready to run. Here's also a video but I recommend emulator or the real machine with Harmony card. it simply looks best there to due the low resolution and high FPS.

I dislike the "introduction - effect - introduction - effect"-structure, but the content is excellent.

Absolutely amazing! I do not have a slightest idea how many times you were scratching your head JAC!, but your stuff were applauded many times during the compo!!!

If you wanna go to SV next year, we must support Grey! He did SUCH A GREAT job ALONE(yes!!) that I dare to say I have never ever seen such a dedicated and motivated dude working ALONE...

But it is not the place to talk about it.
Once again, a worthy winner of first ever in the Polish scene history Atari2600 competition!!!

Not a big fan of the demo's pacing, but the fx are outstanding.
rulez added on the 2011-11-14 17:39:16 by すすれ すすれ
very very successful!!! adding a shadow to the twister is a really great idea. after reading the paragraph above starting with "I wanted to create ..." and watching the demo, I can easily say that you've done what you wanted to do really well. :)
rulez added on the 2011-11-14 17:54:20 by Skate Skate
Very nice.
The pacing could have been a little better. I like the way the text is done and using the ball to give the twister a shadow. The music is also pretty good. My plasma remains undefeated though :)
A worthy winner overall (haven't seen the compo results yet - I'm taking sim's word)

In the future please don't use AUDCx=4 and AUDFx=0 for silence. This creates an annoying high-frequency beep around 15 kHz in both MESS and Stella. I'm not sure what happens on real hardware yet, but I suspect the same.

For the folks lacking emulators:
YouTube via JAC!'s channel
YouTube via my channel - better audio (I hope you don't mind)

As you say, it's probably hard to code on this compy... But you bring us this brilliant demo, moreover with very good design. I especially like the falling fonts' blocks, the twister and the screx.
Well done! :)

congrats Jac! ! It was a real pleasure to watch this demo on SV. Other demos were amazing as well, but not so long and complex . It makes me wanna buy Harmony cart and 2600 and start coding on this machine. Thanx

Perfectly right, fixed in V1.1 and all linked downloads (bin/src/video) now. Check the end of the ROM to see which version you have.

I was baffled when I found out here that I cannot hear anything beyond 14 KHz anymore. 39 years - too old or just too many demo loud parties? I can only hope that Jukub does not complain that I ruined the roughness of his tune now :-)

>Atari 2600? Isnt that the crappy console?
C'mon - a wooden box with 128 bytes of RAM is not crappy - At least is was not in 1977 :-) I've created a label and am planning to create some real carts with this so people can put it into the real thing or shelve it. So if you are interested, just drop me a mail. Maybe we can get some discount from AtariAge then.

I got multiple requests from people who'd like to run the demo in a loop on presentation hardware. Hence I freed some more bytes and made it restart 10 seconds after the end.

I will order another bunch of real labeled cartridges for this. If you are interested in a cartridge, just send a mail.
