    64 colors is just what the color RAM (a portion of the VRAM) can hold at any one time. It doesn't mean that's all it can display on screen at any one time.
    Sonic 2, for example, displays 75 colors on screen in the Aquatic Ruin Zone. It does this using a mid-frame palette swap technique, which allows it to exceed the 64-color limit in the same frame.
    The Sega Mega Drive also has a shadow & highlight effect that triples the colors, up to 192 colors on screen. A number of games use this effect, like Vectorman and Toy Story. Sega used a similar effect in its 16-bit arcade systems (for example, extending the Sega OutRun system from 4096 to 12,288 colors on screen).
    If you combine the shadow & highlight mode with the mid-frame palette swap technique, you can get up to 225 colors on screen on the Mega Drive. But no Mega Drive games actually do this, since it would cause significant slowdown.
    Hackers have also unlocked a hidden lo-res, 160x224 resolution, direct-color mode, where it can display 512 colors on screen (i.e. extending the color RAM by sacrificing half the resolution). The only known Mega Drive game to use this mode is a fan-made port of Wolfenstein 3D, which displays 256 colors on screen (like the PC original).
    And finally, if you enable shadow & highlight with direct-color mode, you can display 1536 colors on screen. You can't use it for any actual games though, and the only Mega Drive ROM that does this is a simple color test ROM with a static image.

      Hello ! Can you give links for these demos. Except the hidden low-res, all other possibilities are tricks to me to render special effect. I'm still wondering for some of theses how they can do more than 512 colors, as the RGB definition is coded 3:3:3. Maybe displaying two colors rapidly on the same pixel, so the human eye appy a mix or see some kind of transparency. But there are always counter-parts to this.

      @Manveru31 yes, and we must say that this is done with 4 pals, it is another restriction. but I've read that there's a "hidden low-res" that allow to go up to 512 colors (see info about titan 2 demo)

    Has anyone ever pulled up the COLOR TEST on California Games for the Mega Drive / Genesis? It shows a grid of 224 colors on the screen. That's all the proof I ever needed that this system can use tricks to put more than 64 colors on the screen at once.

  • @SegaFanatic5188
    @SegaFanatic5188 12 лет назад +24

    What Sonic does is a mid-frame Palette Swap. Basically you send a Horizontal Interrupt telling it to change the palettes being used beyond a certain point of the frame while it's drawing. If you want to go for pure color counts it's possible to display 512 colors using this effect. There is also Shadow and Highlight which can change the intensity of a color without costing a palette entry. This can triple on screen color counts. So combining the two it's possible to display 1532 colors.

    Toy Story and Vectorman are up there. It's really hard to say, depends on what you think is impressive. Virtua Racing certainly pushes way more polygons than StarFox and at a much higher framerate. Red Zone has super smooth, full screen FMV, Ristar pushes insane color. My picks though would be Thunderforce 4, Phantasy Star 4, Shining Force 2, and Streets of Rage 2.

    Just like the Genesis, the Super Nintendo also had a more limited color palette during gameplay and could display a higher number of colors on still images. As standard, Super Nintendo games were at a lower resolution with higher number of colors while the Sega Genesis standard was higher resolution with less colors. However, both consoles could increase or decrease resolutions with lower or higher number of colors accordingly.

    There had to be SO much beam racing in Vectorman and Toy Story. I'm impressed Vectorman pulled that off, and at 60fps on the hardware too! Toy story they *really* had some highly optimized palettes for most of the game and then on the cutscenes they spared no cycle on putting as many colors on screen as they could.

  • @poa9s
    @poa9s  12 лет назад +9

    Wasn't really the CPU, just the way it was designed. SNES actually had a slower CPU, but could display more colors. Which is why many SNES games (especially early ones) tended to have quite a bit of slow-down. I believe the graphics chip used in the Genesis was an upgraded version of the one used in the older Master System, I think.

    Fascinating video. I can't say it really surprised me much, as there were certain tricks to make Genesis display a little more than 64 colors, I think mostly by using lighter or darker shades of the same color or something. It just a shame the Genesis couldn't show more, considering the older PC-Engine (TurboGrafx-16) could display even more colors at once than the SNES. Even though its palette was the same as the Gen.
    The most colorful games I remember were the Sonic series and Gunstar Heroes

  • @dmac7128
    @dmac7128 7 лет назад +26

    One technique programmers used was dithering It involved taking advantage of a quirk (banding artifacts) of composite NTSC signals. When 2 or more colors are interlaced together, they give the illusion of more colors. Examples of this can be found in Super Hang On, Space Harrier II, Outrun and Afterburner II . You end up with games that appear to show more colors that what is actually rendered.

      The closest I could get was enabling VSync, 50% scanlines, TV Mode (CVBS), and brighten. Any other render plugin is trying to make the pixels look finer or less angular in higher res.
      In MAME, one of the shaders tries to add a small bloom effect which is what you should be looking for as brighter pixels emit more light which in turn bleed their color on adjacent pixels including vertically over and on top of the scanline as the light bounces in the glass layer. This is what gives a slight anti-aliasing effect around contrasted sprites which then add themselves to the next image frame as the persistance of vision effect fades.

  • @DrunkencoderPayk

    sure it can. as with many 2d consoles, there is a h-blank interrupt. when the display ray reaches the right end of your tv, there is a short amount of time where you could swap palettes. so you could easily display 64 colors on the upper half on the screen and 64 completly different colors on the lower half (for instance). you could actually use this trick on after every scanline

    Even when it goes below the 61 color limit (keep in mind 3 colors are transparent so they don't count), Toy Story looks really nice for a 16-bit game. Have you ever measured Ranger-X's color output? That was supposed to produce 128 colors using a hold and modify technique similar to what was used on the Amiga.

    Honestly, you look at these games (especially Vectorman & Eternal Champions) & both games still prove they could kick SNES's butt even with so many less colors available on screen at once (64 colors vs. SNES's 256 colors). Ultimately it comes down to how you use the colors; not how many you have. Tons of Genesis titles proved that.

      Right, pre-rendered graphics. Doesn't make it more colorful. Personally I think Sonic 3 is a FAR more colorful game and takes advantage of its color way better than Donkey Kong Country did.
      Donkey Kong Country is revolutionary and looks great for 16-bit nevertheless. What they did was a super cool idea and it worked amazingly; I have nothing against the game.
      However, Sonic 3 took advantage of its style and did it better than almost any other game around the time. It's just way more colorful than Donkey Kong Country, tbh.

    Color count is not so important on this context because is possible port a 256 (or more) colors image to 64 colours without loss of detail using palette optimization. That is, the image will look as the same even when is using less colours. The trick is that each tile don't goes beyond than 16 colours, color depth was the same on video game machines back on time.

    It's not the case that the Megadrive can't show more than 64 colors: It's that it can't (realistically) achieve more than 64 AT ONCE. By rewriting the palette on the fly you can show more colors, but the maximum at any time is effectively 64.

      The CPU often has less to do with the theoretical capabilities of the system than the video display circuitry.
      It's that, rather than 2mhz CPU speed difference that marks the true difference between a Megadrive/Genesis & Sega's System 16 arcade board.

    • @TheTurnipKing
      @TheTurnipKing 9 лет назад

      In this case you're better to compare like to like: There are a whole tonne of other systems based around the Motorola 68000 which show what effect the processor clock speed actually has on the output.
      The Neo Geo and the Amiga/Atari ST are excellent points of reference.

    • @TheTurnipKing
      @TheTurnipKing 9 лет назад

      My point is that the Neo Geo's resolution isn't substantially different from that of Megadrive. It's advantages are access to a ludicrous amount of memory space and a much nicer video display processing setup. The extra 4mhz of clockspeed is undoubtedly nice, but what it's used to do is shuttle some of extra data around the display, resulting in very fluid animations.
      The Amiga (500/+) and ST are also quite resentative of this because the two machines are near as dammit identical in terms of the broad hardware specs, but the Amiga is generally considered to be a slightly more powerful machine because: yes, video hardware output.
      You could have the nicest, fastest processor in the world, but if your VDP only lets you draw 32 colors on screen, your game is still gonna look a little crap.

    • @TheTurnipKing
      @TheTurnipKing 9 лет назад

      You're not wrong in the sense that a faster processor should give better results, but it's not clearly equated to an increase in visual fidelity because at some point you have to take those 1's and 0's in RAM and turn them into a display signal.
      What arcade hardware has is dedicated hardware exactly for that job. To again use the Amiga chipset as an example, it has a single custom co-processor designed specifically for the job of making block copies of memory, which is ideal for getting data onto the screen. And that's from a commercial computer hardware design from 1985. An arcade manufacturer can afford to spend a whole lot more on it's dedicated boards.
      Also, I'm not sure how I'd go about comparing the superior number of enemies in the Sega CD port of Final Fight to the Sega CD version ;)
      I will say though, that the Sega CD version of Final Fight does have a noticably diminished number of onscreen colors versus the arcade version. Well dithered, to hide the reduction, but still noticable.

      On the other hand, most Sega Mega Drive games used the 320x224 mode as default, running at a higher resolution than most SNES games. In addition, the Mega Drive's resolution could be increased to 320x448 without any reduction at all in the performance, colors, or other features, like in Sonic 2's two-player mode.
      The Mega Drive had the clear resolution advantage.

      InfinityCraft THe sound isn't better actually, it depends on your "design specification". Back in those days Memory was an expensive thing to have, and Sample based would take up far more than an FM based solution. Also if you choose your coefficients right, you can make some very realistic instruments on the FM chip of the Megadrive, and some really non realistic but awesome sounding ones as well ;). It could do a great distortion effect for instance ;).And if you really wanted to sample, there were software engines out there that could split the PCM channel up into 4 voices, granted it would be a bit of a stretch to use that though, especially since you had better options. As even Square waves (something FM chips often have problems with ) are taken care of via the inclusion of Legacy Master System hardware :). And if you REALLY REALLY REAAAAAALLY wanted more sound capabilities (which for it's time was a bit silly as good programmers could make the Megadrive sing ;))... there is a sound line going through the cart that was never used (Okay the SVP chip adds 2 PWM channels I think) which allows for mixing another signal into it ;).Face it sound wise Meg was very well designed :).Basically an Arcade system ;).

    No single game really comes to mind. A number of games did show off some pretty impressive stuff, especially when it comes to sprite count. Like Batman & Robin, Gunstar Heroes, Vectorman and Ranger-X. I can't think of any single game for the Genesis, like Yoshi's Island 2 was for the SNES (although that did use an FX chip), that really shows the Genesis at it's max potential. Maybe someone who knows of one will reply.

    The Genesis could utilize a trick known as 'hold and modify' to increase color limits, but was restricted to backgrounds only if I recall, thus the reason the Toy Story cutscenes had more colors than the actual gameplay.

    I believe the genesis could only address up to 32mb (megabit), but if using bank switching or some mapper (I can't remember), it has a theoretical limit of either 128 or 256mb. That fan made Pier Solar for instance is 64mb.

  • @RuntTyson
    @RuntTyson 9 лет назад +2

    Oops I just saw your ranger x video. It barely went beyond the threshold the actual threshold was supposed to be 61 but ranger x used a lot of well done dithering which gave many the thought that it went far beyond the 61 limit. Also back then the scanlines in. CRTs further blended this well done dithering between color values

    • @poa9s
      @poa9s  9 лет назад +5

      +HotNavyStud Oh yeah totally. Not only did they blend, but if you arranged pixels in such a way it'd cause interference when displayed on a CRT (using composite cables). When watching tv/movies you'ld want to avoid these kind of errors, cause it usually made the image look bad. But it could be taken advantage of in games to create new effects/colors.
      For instance, in Sonic 2 the glass pipes you would travel thru were just simple vertical/striped pixels since the genesis couldn't do transparency. If looked at in an emulator or rgb output (such as this example), it looks like this www.chrismcovell.com/gotRGB/screenshots/Son2CRGB.jpg . But when viewed on a CRT with normal composite cables, it looks like this www.chrismcovell.com/gotRGB/screenshots/Son2CComp.jpg . Pixels get blurred together to create a transparency effect, but you also get interference errors which actually create new colors over the glass tube. It's really quite amazing.

      The jail bars of rainbow color you see over the glass tubes are actually present in repeating patterns over the entire screen, they're just more noticeable on solid colors and bright colors. The rainbow jail bars is actually a hardware problem with the video encoder chip on many Model 1 Genesis / Megadrive system versions.

    On side note, I really would like to see Sega make one last Sega Genesis game using todays tech and development tools. Really go out on it, use maximum ROM size and maybe an extra chip or two to help with processing. And release it as an official genesis cart (same style case and instruction booklet). It'd surely be a money-loss for Sega, so there's no way they'd do it. But it'd be interesting to see...

    @markpenrice6253 7 лет назад

    What, there was a question over it? It's a paletted system that can alter its palettes midscreen. Of course it can show more than the static-palette max. I think you can do it just casually using shadow-and-highlight mode anyway. Certainly there was a bit of that going on with at least some of both the over-64 and sub-64 scenes shown in this video.
    Thing is, shoving new colours into the palette registers takes bus and CPU time, so if you've got something that's already extremely processor intensive like Virtua Racing, of course it's not really going to bother increasing the colour count if it doesn't need to...
    Still, as both systems show, it's not necessarily how many colours you can display at once, but what you do with them that counts...

  • @markpenrice6253
    @markpenrice6253 7 лет назад

    NB, did I miss something? Actual playback, Toy Story (outside of the cutscenes) peaks at 66 colours (which may be an unintentional glitch, even - a palette change that was supposed to happen between frames but happened midframe by accident, maybe with a temporary half frame showing messed up colours) ... but at the end, the countdown says 105? Where did the other 39 come from?

  • @RichardCraig
    @RichardCraig 12 лет назад +1

    I do have one question. Did you run the color analysis on a compressed video? Any compression artifacts will introduce colors that weren't there. I've seen many articles looking into this, and most of the false reports of over 64 colors are only due to image or video compression. The Genesis could use an overlay color, like underwater in Sonic, that does potentially introduce more than the standard 64 colors, but that's kinda cheating since it can't be used but on a portion of the screen.

  • @Oerg866
    @Oerg866 13 лет назад

    Problem is, that the amount of colors per frame is irrelevant. You can change color palettes from one frame to another or even mid-frame and introduce a flickering effect, which the human eye will not notice because it is too slow to realize this, hence you actually see more.
    There is a theoretical thing: Every Horiz. INT you get enough cycles to change 3 CRAM words. This would mean that you can display 61 + 3 * 232 colors in total, if I'm correct (THEORETICALLY)

    3 use shadow licht.
    4 rely on rf or composite video signal.
    that way, you can virtualy view up to 256 colors onscreen.

    I have never heard the claim that blast processing was a trick to display colours but even that is true it was used for marketing since the ads were clearly implying that blast processing made the system faster. The ad with a TV displaying a Genesis game on a race car and a TV displaying Super Mario Kart on the back of a slow moving van like veachile was clearly not advertising that the Genesis can display more than 64 colours, In fact that ad never even mentioned the term colour. Also an add for Sonic 2 mentioning that blast processing made him faster than ever clearly shows what direction Sega was going since the term colour was not mentioned there either.

    It could brute force the effect in a sense, through good software programming.
    To me though mode 7 looks like shit. I'm more impressed with effects like you see in games like Dynamite Heady or Thunderforce where tons of layers of parallax or sprites are used to create and illusion of 3D.
    Toy Story's cart racing section not only has a mode 7 esque floor, but scales sprites all at a smooth framerate. It makes me wonder if some carts actually overclocked the CPU to 13Mhz or something.

So one example you gave, the Genesis absolutely mogs the SNES and the other example is extremely cut down on the SNES. Flashback intro video for the Genesis is running at a higher frame rate, as it outpaces the snes once you get to the part where he jumps on the hoverbike.

    Every game shown demonstrates a ton of dithering, which is an effective a form of pointillism designed to simulate the appearance of different colors than the Genesis would normally be capable of displaying. While people using emulators will of course be left out in the cold, anyone using a real CRT TV will notice that the patterns blur together, thus giving the illusion of more colors.
