HEOHdemo - an NES demo 

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).

Look like i want to load new effect through ACE

@@shiru8bit C? Doesn't the NES use 6502 assembly?

@@palaceswitcher source is there.

@@palaceswitcher NES has 6502 CPU. You can program it directly in 6502 assembly, or in a high level language, if a compiler is available. There is a C compiler.

Все уже знают,

Tomas Augustinovic it’s not actually 3d it’s just making you think it’s 3d/ it’s an 8-bit cutscene

@@logana4260 it's still a "3d effect"

Yeah I guess so

@@animacorenight1282 yeah you can compare it to the parallax effect (3D sense of backgound depth) commonly called pseudo 3D

But it could not be used in a game sense it used all possible sprites on screen

but why tho?

do you know of any more?

@@MaxOakland check out high hopes, it's the best one imo

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GPG6a__Q0Sg.html it's probably this

@@T1MAGEDDON It comes from this commercial I knew this was familiar "Dendy, Dendy, мы все любим Dendy" "Dendy играют все" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jyntM5lynvY.html

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.

That's easy, we just need to push it a bit harder! Jokes aside, I believe a lot more can be done, we just need some more demoscene love for the humble NES.

@@shiru8bit Are you thinking of doing the same thing with the snes

Blyast-pre-rendering

Thanks! To me that's the most important reason to do things like that - to inspire people.

A fun fact: the part with the effect is a local cultural meme - it used to be a TV company logo that jump scared many kids back in the 90s, so they're remembering it till this day.

@@shiru8bit I did not know that! Great stuff indeed!

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.

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.

As for how the rotating tower is done, please check this video; it's essentially the same effect: m.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fV9BqqU17DM.html

@@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

@@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

Battery Yes includes!

Thanks! The N is yet another spoof, it looks just like a reversed cyrillic letter. You know, Nintendo wouldn't be happy about their trademark being used, now that's a parody, so it can be claimed as fair use.

1:24 says "INSPIRED BY ИINTENDO"

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.

Not yet, the party is not over just yet, prizegiving is going on right now. Will be added soon.

Sorry about the latter. Demo greets are always a lost case to me, because no matter how hard I'm trying, I keep forgetting a lot of people, including the most obvious ones. Prolly need to make a demo that would be just a huge greets part!

@@shiru8bit Hah no worries mate, I totally understand, especially since the NES scene is pretty big (and that's not a bad thing with so many talented people) I can wait 'till the next demo ;)

Критичный к скорости код здесь всё же на ассемблере (прерывания по строке и копирование больших блоков в видеопамять), но в остальном да, более-менее можно что-то делать.

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.

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.

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.

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.

@@shiru8bitWell, if one day you do give it a go I'd love to see that. :)

I can't, as I don't have a NES and/or Flash cartridge to make it. There is a number of recordings from the actual hardware done by other guys, though, like this one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1xLVRGtgKcU.html

Так это и не 3D...

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.

@@shiru8bit Спасибо! Побаловался с этой программкой: www.dropbox.com/s/f6i2twi52pn2r9c/stalker.nes?dl=0

With the end screen being a bloody Mortal Kombat fatality audio.

One of a couple of my most hardcore followers, I suppose. It came 6 minutes after the video has been opened to the public, imagine the dedication.

Да.

No, these are programmed effects, although many of them rely on various precalculated animation techniques. FMV on the NES is totally possible, though, stay tuned.

Точно так же, как и колыхающиеся листья пальм в Contra. Да и, собственно, так же, как и обновление тайлов в любом сайдскроллере. Дондя умеет обновлять тайлы, да. Открытие!

Why, there is a Doom kinda-port for NES. It is powered with a Raspberry Pi on the cart, though. Unfortunately, a barebone NES can't run a Doom-like engine with any reasonable speed in any form of shape.

@@alkolove1 ah ok

То есть, наличие Elite на донди, где процедурный графон, ранее не впечатлило. А демка со сплошными пре-рендер анимациями - впечатлила? Странный ты....

Спасибо за отзыв. Демо не тестировалось на реальном железе, так что это был самый первый запуск, поздравляю! Проблемы в некоторых эффектах возможны, даже самые точные эмуляторы не очень соглашаются между собой. Через некоторое время планируется финальная версия с исправлениями подобных проблем.

shiru8bit они кстати прикольно смотрятся, как будто под музыку играют :) Вообщем сделал видеосравнение на железе - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mhYp-jLK5AI.html

@@Bugrim спасибо за сравнение! Очень интересный результат, появилась ещё одна запись, с AV Famicom, и там глюки другие, совпадает только дрожащий пиксель под inspired. Полос на названии нет, зато сильно глючит бегущего Марио. Но это хорошо, т.к. демку починить под железо определённо можно, а проявляющиеся сейчас глюки будут полезны авторам эмуляторов для повышения точности.

shiru8bit глючный марио появился в конце, при тестирование на денди джуниор, ну и полоски остались.

Демка вообще супер. Мне особенно начало понравилось, и внезапный ВИД с надписью END.
