Hidden Secrets of Sonic 3's Special Stage Revealed

[@tarotcard0371]

That Red Star trick has to be one of the most clever use of Pallets I've ever seen.

[@tensevo]

Its good but pallet swapping to save memory seems to be used all over the place on 2D 8-bit and 16-bit games. Waterfalls are the most impressive to me, but the chequered ball is also good too.

[@alieneko_nyo]

indeed!

[@Gna-rn7zx]

*palette Yes!

[@GothAlice]

@@tensevo Water, fire… many of the things we'd use particle engines for today are more efficiently implemented using palette tricks in the old days. (Water sparkles, twinkling starfields, fades of sky from daytime to nighttime, …) Writing my own video codec (which was *essentially* a stream of PNG frames using 1-bit transparency to exclude areas from update in the given frame) I also allowed each frame to define a new palette, if needed. As a result, some components of any given encoded animation are encoded purely as palette changes, given sufficient availability in the palette.

[@richardcranium4830]

The Amiga makes great use of cyclic palette for animation in loads of games and demos.

You could implement the source code of an SPC playback engine into your modern game. I suppose it's a different story for remastered/remixed tracks though.

[@BlueSatoshi]

There's also a yellow sphere, that launches you a few spheres ahead. Stealth made a proof of concept Blue Sphere 2 that added a green and pink sphere. Green spheres turn blue when run through, so you gotta clear them twice, while pink spheres randomly(?) teleport you to another pink sphere. I think it may have been implemented in Sonic Mania, but I'm not sure.

[@giovannidotgen]

The yellow sphere was used nowhere in Sonic 3.

[@everardogarcia6047]

[@pacsonic9000]

You should check out the Sega Genesis game Red Zone. It haves a lot of effects including FMV in the way you did the SEGA logo and the Game Over screen in Sonic 3D Blast.

[@jasonblalock4429]

Not to mention that most of the main gameplay uses a pseudo-3D effect a lot like the tricks he used to make the backgrounds in Toy Story's platformer levels.

[@arciks11]

From same Developer there's also Adventure of Batman and Robin on Genesis. And it has some crazy effects in spots. Especially in Mad Hatter levels.

[@heroicdog2824]

I was guessing that they would of used pallet swapping for all of them. Pretty crazy the bounds people had to go through to store memory back then.

[@Nuthouse01]

Modern ones get less respect because they are crude - the use straight forward codecs for audio and video. They treat memory very reckless, where game take up GYGABITES of memory. Game engines are pre-made, things are whole lot simpler. Their coding is sloppy, because the engine has allot of fool-proof securities that forgive allot of things to coders.

[@TorutheRedFox]

@@digimaks don't generalize things there still are games made from scratch on engines made in-house, sometimes specifically for the game, like in the case of literally every single game that Media Molecule has ever made

Damn, working around these types of memory limitations really brought out some genius programming tricks. That's what's so fun about dealing with older hardware, figuring out how to get it to do what you want. There's usually a way, you've just got to be clever in order to implement it. Nowadays games just release with massive files sizes. Like excuse me... 100gb for a single game? That's like an entire hard drive if you're playing on a computer from only a couple of years ago.

[@OKeijiDragon]

Holy smokes, I was just thinking last night about how Sonic 3's special stages were made after watching your Sonic 2 special stages video. And now here we are.

Your explanation here was pretty much spot on. I've known this stuff for a while, but your explanation of it is pretty easy to understand, and I suspect that someone else who hadn't gone through all this code before would probably find this a very useful resource.

[@scramblesthedeathdealer]

I dreamed of designing video games as a kid. Then I realized how difficult it was, and promptly gave up on that dream 😆

[@QuickTimeVelocity]

I didn't. Just last year I started a class in coding, and am currently learning web development, and I know soon enough I'll work my way up to knowing what it takes to code a game myself, because I have a soul filled with DETERMINATION.

[@TorutheRedFox]

I also dreamed of designing games as a kid but the fact that it's difficult didn't stop me, and for a while I just overanalyzed my favourite games to get an educated guess on how it works, and later when I actually learned how to program started to implement those ideas to see if they work or not, and am now working towards starting a full project using my skills you shouldn't give up

[@scramblesthedeathdealer]

[@gc8972b]

@@scramblesthedeathdealer and what about graphic design / 3d modeling and not the programming itself, did you consider that back then?

[@RazorFoxDV]

Woohoo! I requested this one in an earlier video and it happened! Based on previous videos I'd seen, I figured it was either something along the lines of the palette swapping used for the Sonic 3D "SEGA" logo or the animated ground used for Mickey Mouse being chased by the moose. In my limited knowledge, I figured that either of those could conceivably work, but the floor's rotation was what kept making me hit a wall. Thanks so much for breaking it down!

[@KalokesMysteries]

As usual, an amazing take teaching us what many tricks were used to create crazy effects back then! And I think this is the first time a Coding Secrets video took a clip from another video in the series to further explain a trick. It's awesome.

[@Anthony-pz3hg]

These videos are great... all of these techniques need to be documented, programmers these days don't have these challenges... they have unlimited resources and just make games 60gb without a care in the world. This style of game making will become a lost art... a bit like how no one knows how they built the pyramids haha

[@friendlylaser]

You can't do much tricks to compress 50mb 8-layers HD textures besides general compression. Modern games do use a lot of optimization tricks and push hardware to the limit while rendering, even one modern game can fill up entire book describing techniques. But you cannot compress HD assets further. If you have hours of dialogues you can remove some audio channels, but you can't compress them too much.

[@Wryyyong]

@@friendlylaser Pretty much, gamers tend to not realise just how much space highly detailed maps, textures and 3D models can use up, even with aggressive compression.

[@jonweinraub]

When he revealed the animation by switching palettes my jaw dropped. I don’t think I have the intelligence to thought of such a clever technique. In English. Never mind actually coding it.

[@satibel]

@@jonweinraub it was a fairly well known technique at the time, you'd palette swap a lot because it's an easy way to add content sometimes sacrificing only a few colours for a totally new image.

[@Sinn0100]

I know the Genesis does not have built in sprite scaling...it can scale sprites through software. There are a few games with this technique without any specialized hardware add-ons. For example, there is an amazing fan translation of Wolfenstein 3d that runs on a stock Genesis and it's amazing. EA made a helicopter game that ran scaling not as a trick like a boss fight but throughout the entirety of the game...I think it was called Red Zone.

Good old color cycling :). Half the fun back then was finding smart ways to do effects with limited resources.

[@DukeDudeston]

I think the reason they didnt wanna dip into the pallet swap is because they knew they will have to change the colours of the checkerboard sphere at some point, and this would have possibly caused problems later on? There were 7 special stages and I think each one used a different colour sphere, so having the rotations using different colours for animation could have messed with this, as you said it would have reduced the amount of pallet swaps and in the 90s games NEEDED pallet swaps.

[@aceoyame2619]

I remember suggesting the s3 special stage for a coding secrets video. Thank you for making it happen! I can't wait to see what's next

[@werewolfdev]

Excellent video as always! To answer your last point, I think it's important to remember that "Sonic 3" and "Sonic & Knuckles" were originally intended to be one game. Of course, we got 2 different games, but regardless there's 14 special stages: 7 chaos emeralds, and 7 super(?) chaos emeralds. So, I'm guessing they opted for a wider color palette to ensure there's enough variety.

[@KiyokaMakibi]

After you did that video explaining the SEGA logo from 3D Blast, I was playing sonic 3's bonus level one day and I thought to myself: I wonder if this is using the same method.

[@tearlach47]

You could've shown off how the game stores the map layout of any given special stage. It's a false sphere, only an illusion of course. As you can tell from a globe with latitude/longitude lines, you can't exactly tile squares on a sphere perfectly all the way around. The layouts are all just squares; when you reach one edge, you go to the opposite edge of the square like a game of Asteroids.

[@KuraIthys]

Yeah, that's pretty typical for games, owing to the fact that it's really easy to code. Ironically, you can in fact map that onto 3d geometry, it just doesn't look like a sphere.. If you wrap a 2d area the way games frequently do in one axis only, you've created a world that's cylindrical. The worlds that allow traversal across both axes are actually mapping onto a toroid (donut) shaped world in 3d... So, every time you see a game do this, what you're actually witnessing is something taking place on the surface of a donut. xD

[@lauson1ex]

Make a video on the boundary flood-fill algorithm used to check if blue spheres are completely surrounded by red spheres. Or a video on how the 3D positions within the special stage are stored.

[@cst1229]

For the storing the special stage thing, if you mean how the stages are stored in the ROM, it could literally just be a 2D grid which denotes what sphere is on an area.

[@RetroSegaDev]

Very neat! Great to understand how this was pulled off!

[@kapparomeo]

I've just bought Sonic Mania (three years late!!!) and been struggling with the Get Blue Spheres special zones (gosh, these are much harder than I remember 25 years ago...) so this was very timely. The palette swapping to simulate animation is quite ingenious. The star bumper being just a recoloured red sphere was something I never knew before.

[@sweetpeachnectar]

for me it depends on what version of mania you have. i first bought the ps3 version in which I felt the special stages were unplayable because of a slight delay when you turned. and you can believe me if i say I played these stages to death in 1994 (hint: just watch my videos. hint, hint. xD). on switch they fixed this issue, where I could get all the emeralds properly. still don't know what exactly they messed up, but there's surely something off on ps3.
