HEOHdemo - an NES demo

[@TheMaskarad]

this demo proves that making demos is 1% coding and 99% making it look like its done in realtime : D

[@shiru8bit]

Yeah, kind of agree, this one is all about making an impression. Coding isn't strongest part here for sure, it is done 90% in C, after all. Technical part was mostly about finding out tricks that would work well with the platform specifics, finding ways to create/prepare/convert/precalculate content, handling all tiny details (20% of work in 80% of time).

[@ExcitingOnion]

I'm working on one right now. Actually, it's more true 3d than here, more like the original Wolfenstein with free roaming. But not much texture mapping yet of course.

[@MaxOakland]

This looks awesome. I want a video on how each thing was done

[@HaroldoPinheiro-OK]

At the spinning cartridge part, if you look carefully, you can see it's not perspective correct, that is, the part of the cartridge that would be closer to the viewer isn't getting larger, and the part that would be farther from the viewer isn't getting smaller. Basically, that part is only stretching and squashing parts of the background in a way that kinda looks like rotation, but isn't. They are probably using line interrupts to change the Y scroll register between one line of the screen and another. By skipping the drawing of a few lines, that can be used to vertically squash some parts of the background.

[@HaroldoPinheiro-OK]

The maze part, on the other hand, looks like a full screen animation, similar to how the mazes in Phantasy Star for the Sega Master System are done.

[@HaroldoPinheiro-OK]

As for how the rotating tower is done, please check this video; it's essentially the same effect: m.kzbin.info/www/bejne/nIecc6SnipZqeq8

[@MaxOakland]

@@HaroldoPinheiro-OK That’s really cool. Apparently, Y scrolling interrupts weren’t able to be used that way in early NES dev and there’s some fancy trick to get it to work that people figured out fairly recently. I wonder what the trick is

[@MaxOakland]

@@HaroldoPinheiro-OK I’m curious about the specific details. Like how did they manage to do fullscreen animation on a NES? I haven’t seen that before anywhere else

Actually, there is no such thing as a standard NES palette. Every and each emulator uses a different one, sometimes very different. The same happens on different TV sets and NES/clone versions. The video uses the default FCEUX palette.

1:19 .....HOOOOW!?!?!?!?.....HOW THE FUCK IS THAT EVEN POSSIBLE!?!?!?!? How can you even do that on the 6502 without each frame being like...2 seconds long!?!?!? I am genuinely impressed. The only explanation is that it's pre-rendered.

[@shiru8bit]

Yep, it is pre-rendered, in the classic demoscene fashion - if you can't do it for real, fake it. Now, even faking it wasn't a breeze, because you can't update much on the screen and because the CHR ROM is used, and it is quite limited in size. As for true rendering, it would require CHR RAM and some expanded WRAM, and I think that updating it actually would take about as long as rendering a frame. A rough guess it would run at ~4 FPS then.

[@NuclearBoi2nd]

Nice, but I want an explanation for the beginning of the video?

[@shiru8bit]

The whole demo is basically a cascade of jokes and local culture references, mostly from '90s. 'Based on true effects' implying that those you'll see aren't true, just based on some 'real' ones. Then Dendy comes up, and Novaya Realnost intro tune plays for a short while. Dendy is the name of the most popular Famiclone that basically brought video games to the public in Russia back in '93, it's logo is an elephant kid. Novaya Realnost was a TV show that helped to establish popularity of Dendy back in the day, dearly remembered to this day. Then demo 'glitches out', and AON intro starts to play, scaring Dendy away. AON is a kind of smartphone for landlines of early 90s, I did a demo for this piece of hardware last year (see in my videos), and it turned into a kind of scene meme by now.

[@VADemon]

incroyable!

[@BlulesBlue]

ok i actually want to know, the n64 logo spinning is some sort of amazing trick or is it just a bunch of images?

[@shiru8bit]

It is a bunch of images, of course. The trick is to store them in reasonable amount of memory and display at this speed. More details on each effect is in the making of article, link in the description.

А вот мне стало интересно: какой максимальной сложности статичную картинку можно вывести на Денди/Famicom? Можно ведь для этого провернуть что-то типа спектрумовского гигаскрина с помощью аппаратного скроллинга.

[@shiru8bit]

Расширить палитру можно только гигаскрином, а увеличить цветовое разрешение со штатного размера атрибутов 16x16 можно аналогично мультиколору, от простых практических 16x8 (программный трюк) до теоретически предельных 8x1 (потребуется хитрое железо на картридже). Нечто подобное уже делали, конвертер называется NES Image Converter 2 (от thefox, автора High Hopes). К сожалению, старые ссылки уже не действуют, там были примеры картинок.

[@inceptional]

Have you done stuff for the SNES that shows off just how far you can push it to do amazing effects?

[@shiru8bit]

Not yet. It is more difficult to make something impressive for the SNES, as its capabilities were well explored in commercial games, and the architecture of the console is good for a certain set of cool effects, but not so much for anything else. So I think it would be more about clever design of scenes than actually pushing the hardware. Still considering it.
