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.

[@johnrickard8512]

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.

[@RetroMarkyRM]

My C64 is currently sulking in the corner! ;)

[@shalroth]

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...

[@sprybug]

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.

[@RetroDawn]

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!

[@earthacademy]

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? 🤔

[@KuraIthys]

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...

Quinn The Quartz It would look the exact same.

[@bangerbangerbro]

Vara Mepresia The TIA is the GPU. It does graphics.

[@Horzuhammer]

..and sound, and input.

[@johnrickard8512]

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.

[@RETROGAMESeurope]

Bellissimo, vedere programmare in questo modo Atari 2600 !

[@StormsparkPegasus]

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.

[@Andrew-xl3gr]

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?

[@Nikku4211]

Well, they are in related scenes.

[@Horzuhammer]

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.)

[@blakegriplingph]

@@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.

[@s2ms10ik5]

@@Horzuhammer I guess the GBA is a machine somewhat similar to the Amiga. I've heard that their computation powers and architectures are roughly equivalent. Indeed, there exists many GBA ports of games from the Amiga era. Even the sound of GBA is reminiscent of the iconic sound of Amiga modules. If this is really the case, then cracktros in GBA shouldn't be much surprising.

[@Clancydaenlightened]

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.

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.

[@vuurniacsquarewave5091]

+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.

[@Longuncattr]

+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.

[@vuurniacsquarewave5091]

+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.

[@Longuncattr]

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.
