Man most of these effects are truly impossible! My kudos to the coders. The 8x1 attributes are "relative" easy (just change the attributes from one line synchronized with the horizontal scan, eight times) but the borderless "amiga copper" lines and the attribute-clear scrolls blown my head.
@@RetroGod1982 Why are you the ulaplus prophets so obssesed that don't even respect the work of others? Ulaplus is absurd and works very bad. It is an expensive and hard to install hardware which offers little difference, and it has no sense because once you update a spectrum with modern hardware, there a lot better options. It's plain stupid
@@xanvision how is it disrespectful? The demo is cool and so are other developments within the community like ULAplus and interlacing. How does ULAplus work very badly? It extends the features of the original Spectrum ULA and enhances original hardware without breaking compatibility. Old and new software can use it. Existing software cannot use features found in other alternative ULA's like the Spectra interface and Spectrum Next. As it works with all Spectrum models and most clones then it obviously works very well indeed, and better than other alternatives. No its not expensive. Its £48 for a Zaxon SLAM+ board and is easy to install; or you can plug in a ZX-HD or MB03+ interface. The Next, Vega and ZX Uno also include ULAplus built-in. Its actually the most common standard for the Spectrum. SLAM+ also includes 2 additional video resolutions and 6 channel AY TurboSound. It offers a lot more than the original ULA and works within the original limitations of the Spectrum hardware so that compatibility is not affected. This is the point of ULAplus. It enables original Spectrum models to utilise an extended 256 colour palette and up to 64 simultaneous on-screen colours. It is not dependant on any particular video mode either and will work with various screen resolutions. Zaxon's SLAM+ also includes the additional Timex video modes so that even a 16K Spectrum can use 8x1 attributes at 256 x 192 or mono at 512 x 192 pixels. ULAplus also allows the user to run both resolutions in split screen mode. It makes a lot of sense but you just do not understand because you haven't even researched ULAplus. What modern hardware can be added to a Spectrum that offers better options? ZX-VGA? This will also offer ULAplus soon. It can also be combined with interlaced mode. ULAplus offers more than any other ULA replacement. You don't even need technical knowledge to add new palettes to old games. There is only the Spectrum Next that offers 256 colours in its own proprietary mode that cannot be used with existing software. Games need to be specifically written for that particular mode to take advantage of any of the features. You also need to run it on special hardware and the Next is not widely available so that mode is useless for existing Spectrum hardware and software. No other clone supports the Next video mode but many clones do support ULAplus. You really have no argument and have made no sense at all. You're misinformed about ULAplus and your reply is pointless since my comment was posted over a year ago.
Very impressive!! I'm an original speccy owner having had a 48K, 48K+ and then the 128K but have never seen anything this amazing to watch and listen to A+++++++++++++
This is outstanding!!! It looks like so much effort was put into this!! The visuals were absolutely stunning (even if a bit dated lol). This woulda blown me away if I had one of those!!
Yes... *YES* ... the colours, children, _THE COLOURS_ Those final pics are quite impressive, even if not as hypnotic as the rest of it. Though I do wonder whether the pictures might look better if they were all more line-drawn (like the first one) rather than photographic, and used an ordered dither instead of error diffusion? Some bits of the photos are just a noisy mess, but I bet the way that the mode works (essentially blending two regular 8x1 multicolour pics together) could work really well for more synthetic, pastel coloured images with more regular dither pattern. Is there a reason why they're only 176 pixels across though? Do the whole set of attributes need to be loaded in for the next line during the blank part, rather than just changing the memory location they're read from?
Oh yeah, I remember "supercolour" from one of the old spectrum mags, it wrote to the colour layer in sync with the graphics readout to get 8x1. Also it changed the border colour in sync.
i still impressing by people who's on assembly language creating such masterpieces! You're all great people! What's dialect of assembly was used for ZX-spectrum demo? And how long it takes to code such program?
Nice work. Was thinking it was 128 before I saw the subheading. The speed of the patterns is incredible. The flavor is different from C64 demos and maybe the VIC and SID are an unfair advantage.
There's even a new model that just released: ZX Spectrum Next! Unfortunately, you could only buy one during the Kickstarter, but they should be doing another one in March 2020.
This is something that I thought impossible even on a Timex Computer 2048 clone with it's improved ULA and it's special 8x1 attribute multicolor mode. HOW IN THE HELL IS A REGULAR SPECTRUM 128K PULLING THIS OFF?!
I don't get how these full screen effects work. There is not even enough CPU time to fill the entire screen, is there? Are they always possible with some hardware trick?
How did you do the mutlicolor picture at 4:17? There seem to be way too many colors even for changing the attrubutes every scanline. Does this demo run on an unmodified ZX Spectrum?
They're probably changing the colors of each 8x8 attribute every scanline, effectively making them 8x1. Then, for the photos at the end, they're rapidly switching between the two screen memory buffers, essentially giving 4 colors per every "8x1" attribute instead of 2.
You say that introspec and i inspired you but if you get hold of a ula+ spectra zx hdmi or vdac2 you really could do even more impressive feats of magic!
Cunado ejecutas la demo en un emulador las fotos finales tienen un parpadeo que no aparece en el video y no se ven con tanta calidad ni resolución. En cualquier caso, el efecto conseguido en un hardware tan limitado no deja de ser espectacular.
Tie obrazky vyuzivaju 25 Hz miesanie farieb, ktore funguje iba na poctivych 50 FPS zobrazovacich zariadeniach, idealne najlepsie na klasickom analogovom CRT televizore ktore maju dlhsi dosvit obrazovky. Na modernych pocitacoch s LCD monitormi ktore obvykle zobrazuju na 60 Hz je toto miesanie velmi nestabilne a nevyzera dobre. Je potrebne pouzit emulator ktory dokaze emulovat 50Hz zobrazovanie na CRT televizore.
In 1988, I created stereo sound output on my ZX Spectrum 128+2. AY Channel A is connected to left, channel B is connected to right and C (as center) is connected to both - left and right. I published the schematic diagram in Interlace demo and short stereo-test later in LCD demo. But todays, most of emulators can setup stereo-output from AY too - you can set panning of AY channels in stereo output as you want.
This demo is made by Gasman. It runs on standart ZX Spectrum 128kB (see description under video) so it surely does not use more than 128kB of memory :)

There are colours here im sure I've never seen on a spectrum!
You can now use a 256 colour palette with the spectrum using ULAplus

This is no ULA+, this is original ULA with interlacing the two buffers of the 128k Speccy.

That tune (3:51) is brilliant!! I've listened to it loads. Does it have a name? :-)
I think that is called arpeggio effect, but I'm not sure.
Beautiful. Regarding the girl that watches herself in the water, it's expressionism for the Speccy! Bravo.

What's dialect of assembly was used for ZX-spectrum demo? And how long it takes to code such program?
Wow can’t believe it was possible on zx
Nice work. Was thinking it was 128 before I saw the subheading. The speed of the patterns is incredible. The flavor is different from C64 demos and maybe the VIC and SID are an unfair advantage.
First primo - great demo, stunning fx, jaw dropping (!)
Second primo - bardzo very fajnie. but where is Jessica Ha... eee.... Yerzmyey?
This is...beyond words. I would love to read the commented (hopefully) assembly for this.
Impressive. Awesome job! The speccy is still alive and healthy.
There's even a new model that just released: ZX Spectrum Next! Unfortunately, you could only buy one during the Kickstarter, but they should be doing another one in March 2020.
I would love a video walking through how each effect was generated and how the hardware limitations were resolved.
You should write to Gasman the author of demo.

Так этот видеорежим в России применяется с 2004 года (Hexagonal Filler, MCX Viewer). Просто англичане его для себя только что открыли :)
This is gorgeous work, Gasman deserves a knighthood!
finally some decent color on the spectrum
Wow! Runs on a bog standard speccy :-o
Though I’m convinced the sound track is dual AY chip / stereo!

No, only software tricks are used. Demo works on standart ZX Spectrum 128 as is.

Ah I see that you explained it: interlacing the two buffers of the 128k Speccy. Nice!
Nice!
я представляю eblo дядюшки Синклера если бы ему показали эту демку году так в 1983
HOW were they able to make the spectrum produce extra colours? And with no attribute clash either?
They're probably changing the colors of each 8x8 attribute every scanline, effectively making them 8x1. Then, for the photos at the end, they're rapidly switching between the two screen memory buffers, essentially giving 4 colors per every "8x1" attribute instead of 2.
imagine if I saw this demo in 1986 lol. I would think it was magic. (well even in 2024 I think its magic)
i'm glad my 8 year old self didn't own this game back in the day. My parents would of found me twitching/convulsing uncontrollably on the floor.

The sound synthesis sounds like a SID. Is it a factory Spectrum?
Of course. The demo runs on original ZX Spectrum 128k / +2.

Well, it's more taking advantage of how a lot of modern flatscreens deinterlace using a simple flat blend...
