"Secret graphic" request?

There is one out of two things I need:

You know there is a "secret graphics" for NES; which is another palette which is darker version of the original palette, which the ONLY ROM that use it
is PALTEST by Loopy? Well, here's what I need:

1: Would anyone please, are you able to make me the palette for GIMP, which the top one is the perfected NES original palette, like the one from Wiki, AND the bottom one is the "secret" dark colored palette that you can only see it by colormap?

or

2: Can anyone tell me how do I get that? Do I put the pure-colored-NES-palette, snapshot, and others in the FCEUX or how?

Are you referring to the colors made by the emphasis bits, as shown in blargg's 432 color demo? ?

@_@......No, that one is TOO complicated, and I feel SNES would be better off to be used instead of that...

I mean the link I gave.

There is two pallete, the original and "secret".

As of the Wikipedia, the Wiki has the most accurate, if not the perfect colors. And I am asking if someone could able to give me a GIMP palette with that perfect palette AND the secret palette that it "relative" to the "WIkipedia" palette that is somehow ripped from emulator.

Why don't you just have GIMP generate the palette you want from that image, or whatever image of the palette you want?

The palette you want is the last one in blargg's demo. Just run it in an emulator that uses a palette you like and get a screenshot, so you can build the GIMP palette yourself.

BTW, there's nothing "secret" about that palette... those are the colors you get when you enable all 3 color emphasis bits.

Hmm..Offtopic, but "An expansion chip that enables 3 color emphasis bit" + video game = how it would sell so quick because of advanced graphics at the old times...beautiful."

So, by the last one in BLLLAAAARRRRRGGG!! (Sorry.) demo, you mean the last row in the first snapshot of the demo? The bottom palette?

There is no special chip.

The only thing I can think of that might connect picture tinting/emphasis (bits 7-5 of $2001) to a "special chip" is the use of an interval timer on the Game Pak (like the MMC3's scanline counter or the FME-7's cycle counter) to assert /IRQ when it's time to turn emphasis on or off.

You don't need expansion chips, a normal NES alone can enable/disable those 3 color emphasis bits at any time.


The use of color emphasis bits doesn't make graphics look particularly advanced, because you can't mix the emphasized colors with the regular ones... when you manipulate the emphasis bits, the whole palette changes, so you're still limited to a total of 54 colors to choose from. Raster effects (i.e. changing the emphasis bits mid-frame) might increase the overall number of colors in a single frame, but you still can't freely mix all 432 colors.


Yes. That's what you get when all 3 emphasis bits are on, a slightly darker version of the regular palette.

EDIT: From top to bottom, the emphasis in blargg's demo are as follows:

1- No emphasis (normal);
2- Red;
3- Green;
4- Green + Red (yellow);
5- Blue;
6- Blue + Red (magenta);
7- Blue + Green (cyan);
8- Blue + Green + Red (dark);

Is there an emulator that is compatible for this? FECUX 21.5 isn't right for me. =w=

(Although this one looks useful to use for scene...)

I know that older FCEUX versions didn't handle a lot of mid-screen PPU changes correctly. I'm not sure that changed much in the newer versions, but you should definitely grab a newer version. Nestopia handles that demo without problems, and I'm pretty sure Nintendulator does too.

Oh! @.@;; That feels like different program rather others! (I kind of wish I know which is the BEST emulator to play games...)

Now, I got the snapshot...which one is the "perfected-palette" like the one in the Wiki, but darker?

EEEEEEEDIIIIIIIIIIIIIIIIT:

1- No emphasis (normal); < Is this the PERFECT NES palette, like the one from WIKI?!
2- Red;
3- Green;
4- Green + Red (yellow);
5- Blue;
6- Blue + Red (magenta);
7- Blue + Green (cyan);
8- Blue + Green + Red (dark); < SO.......this is the one? :3

The demo has no control over how "perfect" the palette is, that depends on the emulator (since the emulator is the one converting NES colors to RGB). This is why I told you to use an emulator that uses a palette of your liking (or one that allows you to tweak the palette to your liking).

But what about the "perfect" palette that is shown in Wikipedia? http://en.wikipedia.org/wiki/File:NES_palette.png and it's "dark" version?

There's no reason to call that one perfect. I especially dislike its mismatched luminance.

Accurate?

Officially, NTSC is the National Television System Committee; unofficially, it's Never The Same Color. Different TVs decode the NES's composite signal in different ways, and TVs offer dials to change how the signal is decoded. So a palette can only be as accurate as the TV you view your NES on.

That said, Bisqwit's generator with saturation set to 1.2 and gamma set to 2.0 should look reasonably close to actual TVs.

Why do you think it's accurate, caramelpuffpuff?

Bisqwit sure makes a lot of cool stuff. That's a neat link, tepples.

...Good question...I guess there is multiple color palette that has the same color as that...

and I don't know if it's true, but in viewtopic.php?f=12&t=10756
if what Shiru said that Wikipedia SNES palette = SNES system palette correctly, I assume that NES from Wikipedia is accurate like SNES.

The Super NES PPU outputs an RGB signal with 32 levels per channel that a separate encoder converts to composite. The Famicom Titler operates similarly. Converting RGB to RGB is fairly simple.

But the standard Famicom and NES PPU, on the other hand, operates in a polar YUV color space, which behaves closer to HSL, directly generating a composite signal by treating the lightness as the level of the signal's center and the hue as the phase of the color subcarrier. The NTSC standard states (in general terms) how to decode this composite signal back to RGB, but TVs deviate greatly from the standard to provide picture "enhancement" "features" that the user may or may not be able to disable from the front panel.

...I see. @n@ ...

I think I understand a little.

On the Bisqwit's NES Palette generator: Can I ask what is the settings set for the (at least closest to) wiki palette http://en.wikipedia.org/wiki/File:NES_palette.png ? The Hue, Saturation, Contrast, Brightness, and Gamma?

(Sowwy for being so picky. ^^; )

You can tell if it looks "accurate" if the colors look evenly spaced, with every color in a row being equally light or dark, and each color in a column having the same hue.
