yeah, thinking the same... but it seems more likely someone will send back a cyberdyne T800 back in time

Yeah, I get a MacBook Pro just to make simple websites 😅

@@KarlOlofsson Everyone’s got to start somewhere.

Self aware

@@markm0000 yeah but it's not like spending time on a MBP making websites is going to magically transform you into a real programmer. Trust me, I've tried...

I´m not a programmer at all, rather a hardware engineer. I would say, this is probobly more about knowing tricks of the hardware then being very skilled with algorithm.. well.. .. yea, there are parts that looks like really good programming as well (like the landscape). A little hint. At 1:08 the border line change color ever so slightly, and the picture kind of shudders a bit. This was done to save memory in the previews segment. The blue border wall is a out of boundaries border wall, until that shudder, than its a text block color border-wall. I don´t know exactly how they address all 16 colors in the graphics mode (might be some mode mixing i´m unaware of) but the image in the middle of the screen is just as large as it looks like it is. So there is no problem having text on the side. I kind of think this is cooler out of a hardware than software perspective. but of cause, there is parts that looks fairly software intensive. Of cause, it might be as simple as they use hardware feature or bugs i´m unaware of. 2:45 they reintroduce the border, the flash is visible here. But they are sort of doing a classic misdirection magic trick 4:27 use a color invert function in 4 layers that where the pointer is moved. I didn´t know color inversion was possible in CGA, but its often used in EGA and VGA. 5:26 is kind of cool because there they are showing the trick

amiga? buhahhahahhaaa

I seriously love my Amiga and has until *this moment* believed it was unbeatable.... W O W !!! ... 4Mhz and less than 500kb of data. W O W again!. I actually have a hard time believing what I just have seen .... This is the *by far* the most impressive demo I have ever seen! And if someone can explain how the **** they made the music beginning at 8:38...please do. The little "funk" bit at 9:11 and onwards really was the icing on the cake for me! .... W O W ! ! !

@@SEngelsg It's possible to play digitised sound through the PC speaker, you use timed interrupts and register tricks, similar to how you'd do it on a C64.

@@rakido7388 yeah I know.. I was amazed when I first heard the sampled sound on a PC speaker with the game badcat in my youthful years. This demo is on another level though....

how many clocks are being used up and what's the strain on the system

That's because it _is_ impossible. These guys aren't mere programmers; they're wizards. So much so, Deep Magic™ is a walk in the park for them.

We’re forty years into the future and I can say for certain that I’m impressed with how much they’ve gotten out of the hardware

Please let me know if they do! I'd kill to see the tricks they're using here!

You can find a very extensive explanation of their previous demo - 8088mph. Very short answer: they manipulated the separate RGB lines on the CGA monitor output individually.

@@MarcKloos err, i don't think that's right. Mostly it's a hack where 16-color text mode characters are compressed to approximate a bitmap mode. It does rely on low level manipulation of the CGA hardware and careful scanline timing

@@penguinx42 still mind-blowing

They used clever tricks, it's not conceptionally possible using conventional methods, it's an illusion created with exceptional machine code and memory management to a high degree

Me too, but CGA clone cards and all others EGA VGA can not play this demo at all or it is glitchy.

That would be great but it won't happen. Almost nobody will be learning to optimize their stuff like yesterday's programmers did. Also, a random computer from 2020 is nothing like one of the very few early home computers that existed back then. Nobody will care. In the past, millions have used the same computer. Today, everyone has a different setup.

Because someone can utilize a 80s computer to blow our mind so there must be someone who can push 2020s computer to the same height of difference ? No. Things don't work that way.

@@mytube9182 maybe they do work that way

Not just that, think about the demos that 2062 people will be able to make with 80s computers.

@@mytube9182 It absolutely does work that way. Most programs today are horribly optimized, there's still so much that can be pushed out of a 2024 PC that we just don't know about. Think about it. A modern x86 CPU runs at several gigahertz and has multiple cores, as well as multiple gigabytes of RAM. If you were to use a very minimal OS (or none at all?) you could utilize pretty much all of that plus typically an actual graphics card. We'll definitely see something like Area 5150 but for 2020s PCs sometime in the next 30 or 40 years for sure.

Same here, I started with C64, then AMIGA, but knowing the Hardware limitations, I sure can appreciate this achievement. 😊👍 To be honest, the C64 aside, I do not think the AMIGA has been pushed this hard yet, as this poor IBM 😅

i got it ;)

It did, in fact, take months. Years, if you add up all the man-months.

IKR I saw worst ST demos

95% of the amazing work in this demo is the result of Viler and reengine, so I'll throw some love their way.

Future?

@@JimLeonard next target ?

Surprise!

We thought so :-) But it was down to the wire if we'd get it done in time for the deadline. There are rough spots, and we'll try to put out a final version sometime.

It does though. The real trick is to 'stack' frames on top of eachother with no vblank in between, so you can trick the hardware to refresh the hardware registers.

Right!? Insane seeing the progress! Keep up the incredible work! This makes me so happy to see!

Thanks! But 95% of what you see onscreen is the work of Viler and reenigne, please send some love their way too.

It's abuse of text mode in some places, yes. The CGA font cannot be changed, so no different character sets.

@@JimLeonard Very cool. I did a little reading on the 6845. I'm starting to get a vague idea of how that could be manipulated for good or evil. :)
