Imagine going to Atari Headquarters in 1977 to the programmers and show them this stuff
They would burn them as pagans.
***** or just jump through the window shouting : "It can't work!!!"
They'd be like "yeah, well if i had a massive 62kb EPROM to play with, i could probably do the same".
Just show a Bit at a time.

Imagine how people would have reacted to this in 1977. They would shit themselves.
Things are a little moist in 2016 I assure you...
They all ain't dead yet
Just call chuck e cheese and ask for Nolan Bushnell
Funny how warner communications bent him over so bad he don't have no Atari brand arcade units in chuck e cheese
He can also use chuck e cheese as capital to re invest in Atari and buy back some ownership of his brand
😂
And both companies can profit because they in a line of business that co benefits, Atari makes games, chuck e cheese is effectively an arcade...go figure
Just like David crane used to own Activision
He had nothing to do with call of duty...
Back when Activision used to make high quality games could be a spoken sentence
And the engineer and development teams got paid a fair percentage based of total net sales income
Not a flat rate regardless of actual profit
The better your code sold, the more you can earn
128 bytes of RAM. I'll never be able to wrap my head around that.
same
Rodney Smith The CPU can address and read from 4KB in the connected cartridge as well.
@@bangerbangerbro four kilobytes? FOUR kilobytes?! four KILOBYTES??!! *_FOUR KILOBYTES???!!!_*
I think the only thing that would impress me more is a demo on the Eniac.
@@mvl71 Yes hahaha. I think these demos probably use bankswitching and that as well so it can use more than 4 KB
Byte it instead. Im stupids. Sry.
imagine if programmers knew how to do this back in 1977 :P 1983 crash might have never happened lol
The crash would happen anyway actually. I don't think there would be a way to prevent it.
@@justinhiggins2090 yeah considering its all blamed on ET. i dont think that what happened. there was too many console doing the same thing and it killed the market.
Too many people didn't feel they were getting their money's worth. It wasn't ET. It wasn't Pac-Man. It was every game. You could spend hundreds of dollars and end up with one or two really playable games.
@@KC9UDX exactly, and hundreds of dollars in 1983 money, about 3x more expensive in today's dollars
You would do something similar but within 4 kilobytes of rom space at max in 1977 because bank switching wasn't a thing yet
Imagine going to in and showing them this demo. I'm sure they will be blown.
lol
There is an absurd amount of fuckery going on in this demo. Well done!
This is really amazing for an Atari 2600! I remember being impressed by the intro screen to California Games, back in the day. However, this demo is the most incredible thing I've ever seen on the VCS.
Now make one for the Odyssey 2.
Lol m.j o way I want ot for the originsl odyssey. I ow that would be a challenge.
That machine actually has more hardware graphical blocks. It has 4 sprites and 12 character blocks. The right guy could certainly do amazing demos with it given the time.
I tried to make a videopac g7000 demo which is the PAL version of odyssey 2. Got some effects done but wasn’t happy with the quality.
That's damn impressive considering the Atari 2600's limitations. Plus, most sprites changed color by scanline unlike those of an NES where there only seemed to be a color limit instead of a limit in where colors can be.
Technically the Atari's video hardware had even more limited colors than the NES. This is of course ignoring the fact that the Atari's video chip doesn't generate frames but lines.
@@johnrickard8512 but the 2600 could output all of its 128 colors at once on the screen! tell that to the NES´s 56 color palette
@@AloanMoreira1 so could the NES with the help of the MMC3
I wasnt aware of this consoles color capabilities, this is the most color ive ever seen in an Atari 2600!
Well, It does have 128 colours to choose from.
The crazy thing is this has more colors than the famicom
@@ssg-eggunner Yea, It is ridiculous.
@@JankPods0201too bad y'all code on pal consoles mostly when the ntsc are better
Faster, more color, and more cycles per scanline
Pal support less colors, runs slower
You must have been French and had a secam unit😂
The one thing I love the most is the fluidity of the men running in Chapter 7, especially since I know of Intellivision's "Running Man" back in 1978.
How on earth was that twisting coca cola part possible?? Absolutely amazeballs!!!
Coca-cola part? I'm still stuck on the AMIGA bouncing ball mocking!
My C64 is currently sulking in the corner! ;)
IKR? I just found myself shouting "F**k off, really?" at my laptop when I saw that! I guess as the TIA is only painting every alternate scaline, you've got every other scanline to do the calc for the next one, but IDK... the resolution is too high for it to be playfield graphics...
My best guess on that is that it used the Player0 and Player1 sprite combined and shifted it's coordinates and contents on every scanline. There was a lot of black space on both sides, which is what got me to that conclusion.
My guess is it's using P1/M1/P2/M2/Ball/PF. That gives you a maximum of 19 NTSC-color-clock-width pixels, 20 four-NTSC-color-clock-width pixels per scanline, and 3 colors (I noticed some gray, seemingly for an almost anti-aliasing effect). And that's without multiplexing any of those 6 "objects". Any of the first 5 can of course be stretched horizontally, where there isn't the need for 19 NTSC-color-clock-width pixels. And the players (and their missles) can be duplicated once or twice, at different, fixed offsets from each other, but that would only be useful if there was a repeating pattern on a scanline that matched one of the fixed offsets.
The twisting effect is purely done by shifting each scanline horizontally (the image this is visible on any line of the "tube" is static), and then there's the vertical "scroll". Lastly, a table could have been used for the entire "tube", as entire tube is just over 3 screens high, and each screen is likely 96 scanlines (or near that), so it's only ~300 scanlines. It's not actually that hard to design and program, but an impressive effect nonetheless, and a cool idea, to boot! This demo as a whole blew me away!

No 1 noticed that the Atari has more colors to choose from then Windows 10?
LOL. True though. Fuck Windows 10
xd
Solar Flare [Who likes uploading SSBU replays] WHY THE HELL ARE YOU EVERYWHERE
I see someone hasn't noticed you can choose a custom RGB value yet. ;p
@@mr.knuckleschannel2924 he is a diety. That's why.
Imagine if you brought this to atari headquarters back in the day. They'd be like, "Wow, now we CAN make text unreadable!"
Jokes aside amazing demo.
I imagine this as one of those weird commercials that come on Adult Swim at 1 in the morning.
I used to use this demoscene to push the limits of various 2600 emulators (such as Stella Wii port, and 2600 emulators made in the early 2000s)
3:02 would be impressive on A SNES. It makes perfect sense this got first place.
would it? the snes actually has palette registers and dma and whatnot, and im not sure itd actually have to be very optimized anyway given the pretty high clock speed
(sidenote: i actually listened to one of your songs right before this. they are all very good)
@@mothcompute Yeah lol I don't know what I was thinking when I wrote that comment. Thanks!
Chapter 8 was especially impressive.
Indeed but Chapter 9 is the icing on the cake! ;)
Coming from a machine originally designed to play variations of Pong and Tank.
Man, I don't think there's ANY 2600 demo that even comes close to this one
It's better than any of the atari porn games, that's for sure.
Excuse me whaaaaaaaaaaaaaaaaaaat?!
my all time favorite demo. out of this world. respect
If 2600 was capable of graphics like this, why most 2600 games are a blocky mess?
Some games. And it's due to programmers without skills and not enough time. And meager production budgets.
Each single screen/segment of this demo would fill up an entire Atari 2600 cartridge from 1980. So there would be no game, just 5 seconds of something to look at.
hard to believe it's on only a 2600. commendable 6502 coding! I especially liked the animated running men.
When I hear this song it reminds me of some sort of giant factory. Like some giant creation is slowly being smacked into shape by hammers and machines, one part at a time, methodicly. Some parts sound like gears grinding, and the such.
I enjoy this!
Reminds me a bit of those crack intros on some GBA roms.
Crack graphic apps have some crossover with the demoscene.
Andrew - I think the crack intros inspired the demoscene. Correct me if I'm wrong, but didn't coders start wanting to make those without tying themselves to piracy?
Well, they are in related scenes.
The ones on GBA roms are a homage to the old 8/16-bit cracktros (C64, Amstrad, Amiga, Atari ST, etc.)
Always wondered how come they made a comeback with the GBA. That's the only non-computer platform I've seen those on (DS roms had them too I think.)
@@PhirePhlame Yeah, the demoscene is an offshoot of the cracktros used by warez groups to brag about their superiority to their peers. While some demo groups have no warez involvement, other warez groups like Fairlight and Razor1911 do participate in demos.
Finally got around to running this on my 2600 (was waiting for a free weekend!). Top effort - totally solid tunes and great routines. Wish I could have been there to see it live!! Hope to see some more in the future :-)
debuglive can you show me a video
And the system doesn’t have enough ram to fit a 5th of a vid so I wanna see
Really good usage of the CPU and GPU of the Atari 2600. Wonder what this would look like on 7800
The 2600 doesn't have a GPU. It's that TIA chip straining itself to do all the work.
Quinn The Quartz It would look the exact same.
Vara Mepresia The TIA is the GPU. It does graphics.
..and sound, and input.
The TIA can barely be described as a GPU. More accurately, the MOS 6507 CPU abusing the crap out of the TIA to crank out far more sound channels and exceptionally superior graphics to what that chip was ever designed to produce. Indeed, programmers of the time figured out that you HAD to abuse the TIA with the CPU in order to get much of anything done with this console.
Tfw a console that came out 13-14 years prior to the SNES can produce a Mode 7-like effect that looks smoother than most SNES games.
Cuz
1 This is a demo not a game
2 This is modern while the SNES games are old
Look up the SNES demoscene sometime. There is stuff on there that makes you wonder if they briefly snuck in footage from a Playstation.
Man every game console deserves one of these.
All this is, of course, utterly impossible on that hardware. Which is what makes it so great!
As someone that used to code Atari 800 games and it’s sound chip back in the 80’s, does anyone know where there was often this stray sprite line or chunk of data going down the screen, often on the left hand side? 🤔
I want a new video recorded with a real 2600!
And cartridge 👍
Mission possible :) amazing demo
Im suprised nobody's ever made custom demos using the pitfall II custom dpc chip, add bankswitching with ram, would provide a noticeable difference
Oh look now someone can one up "Xanax" at the next demo competition to get 1st
That one time the auto incorrect actually became kinda funny...
It's always amazing what people can do with modern development tools and optimization on these old machines. Sadly most of these techniques take every bit of power the machine has so they wouldn't be that useful in actual games.
It's fascinating to look at how a specific team of people created certain solutions out of necessity, then built on them as they realised the weird and interesting consequences of their original weird fixes.
Jay miner and his team did some amazing things.
But consider how they got there;
1. Atari VCS; Built to a budget when RAM was insanely expensive. Solution? dump any pretense of a framebuffer, and have the CPU update the graphics registers every single line.
2. Atari 400/800 - we need to compete with systems that have proper graphics memory. We could build an entirely new chip just like everyone else, but let's take the VCS's design, upgrade it... Then Add a second chip to take over most of the work that the CPU was doing.
As a neat side effect, our graphics modes are defined on a line by line basis, and we have easy ways to sync effects to specific scanlines even when we need the main CPU involved, and we can program an entire sequence of graphics mode changes in advance using a highly simplified list of instructions specific to our graphics chip.
3. Amiga - you know all those crazy graphical effects we could do on our 8 bit atari design? How about we take that a step further and build a chip that can write to a bunch of graphics and sound registers at regular intervals? Now we can do things at scales smaller than a single scanline, and the nature of what we can automate without CPU intervention also became more flexible.
One thing leading to another, creating ever more flexible and interesting ways of manipulating a display.
As an aside, the SNES design looks suspiciously like someone reverse engineered an Atari 800 and an Amiga then added their own ideas to it and put it all together in a different form.
HDMA essentially takes a list of instructions that say to write value X to register Y on scanline Z...
Which is very similar to a display list on the Atari, but with flexibility in what you manipulate closer to the Amiga. (Really, it's very similar to the amiga approach except your timing is restricted to whole scanlines, where the Amiga can do things mid-scanline as well...)
And all of this... Because Atari didn't want to give their game console enough RAM to do graphics in a more conventional manner...
2:29 When you find a clue in swordquest: earthworld
6:48 What is that thing over here?
Awesome ! Can't believe my eyes !!
Stunning. You made those 128 Bytes rock.
awesome for a console with 128 bytes of ram, and no video memory at all.
You demo guys realize you are making poor ol' Jay Miner roll in his grave? "This was not supposed to do this! This was not supposed to do this!" xD
Technically speaking the Atari VCS was only ever intended to play Pong and Tank. Just another Pong console. Little did Atari know at the time that if programmed properly even a lone stripped down MOS 6502 can command hardware to do things it was never meant to do.
Would this work on a flash cart? I'd love to see this on real hardware...
Wow, it starts with Édith Piaf... Non rien de rien, non je ne regrette rien.
Is it the real VCS 2600?
Is everything in sync with the clock?
This is all running on an Atari 2600? Damm.
holy shit
Sometimes it sounds like fax machines.
A QR CODE WITH A 70'S CONSOLE!!!! AND THE MUSIC SOME OF IT BEING IN TUNE!!
Brilliant chiptune!
that ending tho haha NSFW
@Rocket-Powered Suitcase
Just FYI, the running man is a reference to the character from the game Impossible Mission, which was probably most known as a C64 game.
wish didn't do that at the end. kinda made it nsfw and can't post it as many places.
james42519 exactly, i really want to show this to my dad (since he grew up with the atari) but the end prevents me from doing so...
shoopdahoop22 Same here. Really irritating. Completely unnecessary and not even impressive.
Your dads are afraid of QR-Codes?
are you guys serious? o___O
youre afraid of the 8 pixels of artistic nipples?
@@shoopdahoop2221 Just show it to him and tell him not to pay attention to that
Ending ruined it... :/
I have a PAL VCS that would probably break this (timing differences)
That Raumpatrouille reference.
Bellissimo, vedere programmare in questo modo Atari 2600 !
SvOlli muß a) steinalt sein und b) eine verdammt coole Sau.
Remarkable coder!!!
the beep at the start is the same tone and pitch of my alarm clock, it gave me a shudder
99 bytes free
Even on a C64 this demo is amazing. On a VCS2600 it is unbelieveble.
7:30 well seems like a good hardware test if you change the 6507 for a 6502 or 65c02, or a 6502C "sally"
Even possibly a 65816 if you really want some ram and io space and 16bit support
Even intellivision in 1979 used a 16bit cpu
Only thing is dumping the ROM and patching it since you can store the entire thing in ram now, 128k is what I design my 2600 clone around
Plenty for a full framebuffer and plenty left for all the code and graphics along with ROM, and now you have better sound and full Dma graphics with interrupt support. And my antic chip does memory operations in its display list
There some blitter for ya
With it own uart, timer, eeprom, flash, ram, io, clock, interrupt, and cpu core with instruction pipelining, ADC and analog interfaces.. one cmos chip
Looks awesome! Really pushing the Atari to it's limits. Loved the music as well.
If only Jay Miner could see this. He'd probably not believe it anyway.
Great work guys. Man, SvOlli gave me the bug again. Gotta finish my demos!
Bloody hell..... want to know what the some of the old dev from back in the day think of this.
YOU TELLIN ME THE ATARI HAD TEXTURE SCALING?
How the hell did they manage to show all those rich colors! Respect
Was that last one a homage to the Atari porn games?
Amazing demo, especially the music. Just blown away.
No illegal op codes were used in this comment.
this shit is like Crack
1:46 why the f do i love this
Was the atari 2600 not supposed to only view 4 colors atonce, either way, these tunes were awesome and the color demo part blew me away.
+johneygd I think it only has a color limit based on scanlines (a horizontal row of pixels)
I think it's 2 colors per scanline but I could be wrong. The point is, there is no problem switching the selected on screen colors as the screen is being refreshed.
It's like you ask a painter to paint a portrait of you. He draws left to right in thin lines, and you decide he should use different colors midway through. The part of the painting that's already finished will stay the way it was, but the rest will be done according to your new command. That's the idea.
+za909returns The canonical limit per scanline is 4 colors, corresponding to the two players and their missiles, the playfield and its ball, and the background; the colors are set using the 4 TIA registers COLUP0, COLUP1, COLUPF, and COLUBK. The rainbow matrix here was done by changing the background color as fast as possible.
+Sorrig Bowman Now that's something the NES could never do... it only has 4 shades of every color, though there is also a color emphasis mode (for any combination of red, green and blue) and maybe 30Hz color flickering could be ok for producing more intermediate colors.
za909returns
I've read in a text document somewhere that it may be possible to make the NES produce somewhere around 512 colors in a frame by reprogramming the PPU in a similar on-the-fly way. I say "around" 512 since the 6-bit palette has nine duplicate entries and one that doesn't fit in the NTSC color space. I've never actually seen it, though, and I doubt any emulators could accurately reproduce it, though I could be surprised.
there are some code tricks to show even all 128 colors at one one screen. i saw this in "stella lives" demo
UNBELIEVEABLE! This is so amazing!
Oh... Well so much for sharing this. Why did this need nudity at the end :/
Really pushing the limits
HOW IS THIS POSSIBLE?!
I like when it's the comodore 64 boo screen they needed some cpu time apart by adding black like , and when it's the rotating thing there's a black window :D
Wow! That was impressive!
i didnt even think a lynx could do that
The Lynx could do stuff like scaling though, so this is like a cakewalk to that.
How smooth some of it looks though.
Really amazing! I love the music. This would have blown my mind back in 83. Nice work!
Brilliant. insert wb 1.3 lol
This shows how software is king
I have the complete collection of games now on PC platform and all the original sounds work.. I use to programme to my midi keyboards gd stuff
BANG 4:22
rom link?
Fantastic.
Does not look like the Atari 2600 I knew in the 1980, a really really cool demo!
The lack of interrupt lines on the CPU is what always drives me away from getting into 2600 programming... it's just way too restrictive even for me. But amazing demo nonetheless!
sta wsync is all you need
Lawrence Candilas Yeah I have to say I don't know much about the other hardware compontents in the 2600, but I suppose it makes sense, I don't know if the video hardware has a flag you can check to know if the drawing phase is active or the VBlank phase. At least that's how it is on the NES. You can choose to keep checking bit 7 of the $2001 register or have it issue the NMI interrupt automatically.
za909returns It doesn't have a flag, you have to program 200 lines into TIA, then enable Vblank for 3 lines, and some overscan lines, then set INTIM and finish your Vblank stuff before the next frame starts, testing against INTIM before it reaches 0. If you go over your screen flips.
Wait, thats illegal
what is up with chapter 9?!
imagine if we showed this to a caveman and we get our heads impaled with a rock
Nice Demo , very simple I think . Nice Music !!! Our Hobby Tronic Demo 92 wurde sehr zerstört, leider . Weil unser Programmierer nicht den Original Text mit reinnehmen wollte .
Amazing how demo creaters use a system tp it's full capacity
This was recommended, expect a surge of viewers.
Bit like human league stuff 70s travelogue Lp
very hypnotic
Great! Bravo! Super! Incrível! Amazing! Congratulations!
