NES Custom Palette Preferences?

@used2berx Nah, the palette closest to my tv is the sony-cxa2025as-us one.

Oh... My mistake. I didn't even try that one. He doesn't even mention it on his page, so I figured it was something he just abandoned. Those colors do look nice for the SMB title screen, at least on my PC monitor. I'm going to test those out and add them to the compare list for everyone for the games I tested. Thanks for pointing that out. :)

@lilbud Well.... now that's very strange.

I used Sony CXA in MednafenX and got a very different color scheme than yours. (See edited OP above). I don't like the way my Snapshot of Sony CXA looks at all compared to yours. It's pretty much exactly like the PVM Style D93 (FBX) palette looked for me.

Which emulator were you using to get that screenshot?

Anybody know why different emulators might give differing output with the same palette?

Whoops... Nevermind. I had "Autogenerate NTSC Pallete: " set to Yes. So it was using a default Tint value of 56 and Hue value of 72 on top of the palettes. It seems as though whenever you load a new palette for a game that this field automatically gets set to "Yes" for some reason. (I'll have to mention that to the guy in charge).

I'm going to re-take all of them and re-up them in the OP.

Please stand by. :)

@lilbud All sorted out bud. I do believe my output is exactly the same as yours was now.

This is great. Not only do you say that Sony CXA is the best match to your CRT Television, but I happen to think that it is the best looking palette by a wide margin. :)

Looks like the "bug" that forced that auto-palette correction wasn't intentional and even known until now. Developer is going to look into it. Thanks for inadvertently being a part of catching a "problem" that has been a part of the code for well over a decade that nobody noticed before. :)

It's amazing how drastically these palettes can differ. I use sony-cxa2025as-us as well.

[Used2BeRX]

@mediamogul Yeah man. I can't believe in all of my time working with emulation that I've never really paid any attention to this fairly crucial aspect of it.

I don't see the Sony CXA on that picture though. Is it one of them there, or were you just posting that to show how crazy the differences are?

Also, both you and @lilbud are calling the palette something different than the one I got in the zip file at firebrandx's website. If you wouldn't mind, could you check that out and let me know that we're both talking about the same file? I see it in the zip as only Sony CXA.pal in the zip file called Novemeber-2017-Palettes.zip.

THANKS!!!!

'Unsaturated V5' was renamed to 'sony-cxa2025as-us' at some point in time.

I believe the palettes I'm using were obtained directly from the online updater through RetroArch itself.

@mediamogul @lilbud

Any chance one of you guys could get me the CRC value of that file?

The Sony CXA.pal is a CRC of C5929D66, which is a match of the file simply titled Sony.pal in a downloadable zipfile with many palettes in it found here: https://emulation.miraheze.org/wiki/Famicom_Color_Palette

I'm just about 100% sure we're all using the same one, but I just want to verify the CRC.

[mediamogul]

@used2berx

I may be wrong about the online updater, as I can't find a download option, directory, or even a reference to palettes in retroarch.cfg. I'm beginning to think these palettes may be baked into the core itself and not directly accessable.

[lilbud]

@used2berx CRC is the same for my file.

Here are the pictures of my screen (pics aren't the best quality)

Very similar to the Sony palette but only with darker oranges and browns

For future reference, where are these files located?

[lilbud]

@mediamogul On firebrandx's website

http://www.firebrandx.com/downloads/Novemeber-2017-Palettes.zip

[mediamogul]

@lilbud

I mean within a Retroarch installation.

[lilbud]

@mediamogul In the system folder if the docs are to be believed: https://docs.libretro.com/library/fceumm/#custom-color-palettes

[mediamogul]

@lilbud said in NES Custom Palette Preferences?:

if the docs are to be believed

I read that too and also found a 'palettes' directory in the system folder, but it was empty on mine, despite multiple options being available in the core options. I guess a certain amount of them are baked in, leaving the actual 'palettes' directory for custom files.

[Used2BeRX]

Just for future reference for me, how do you select a palette for the NES, and would it then automatically work on all of the games you've already set up without it?

Does the palette work with all 3 NES cores? Most of the games on my Pi Zero run with quicknes. Quite a few of them use Nestopia and the few that won't work with those two use fceumm. Would I have to set the palette up for each emu, or do I just do it once and it works on all of them?

@used2berx said in NES Custom Palette Preferences?:

how do you select a palette for the NES

In RetroArch, the various palettes are selectable from the core options menu.

Does the palette work with all 3 NES cores?

A selection has to be made in each core. Not too long ago, the exact same palette might be named differently between them, but there seems to have been an effort to consolidate the names over the past year.

[Used2BeRX]

Thanks for your help guys. :)

And thanks for those screenshots @lilbud . I didn't need any more selling on Sony CXA, but it looks like you're right about how close they are. Also, thanks for checking that CRC for me so we know we're all using and talking about the same palette.

I'll give your instructions a shot when I get my Pi up and running again @mediamogul . Had to unplug it today to print up some tax time stuff. My power strip has only one non-essential plug, so sadly my Pi has to share it with my printer, and this is just about the only time all year that I need to use the printer. :)

Figured that I'd ask you about that now since we're on the subject though. All of the stuff I've been doing with this palette debate was on the XBox and I hadn't even considered how I was going to pull it off on the RP until you guys were talking about it.

@mediamogul

I finally got around to working on this on the Pi. Good news for most games for Pi 3 users, but bad news for Pi Zero users, I'm afraid.

Because you really have to default to Quicknes for the Pi Zero for compatibility and only use the other two when the games won't boot up, most of the games seem to be stuck with whatever palette is baked into Quicknes. But for Nestopia and Fceumm it's a fairly easy process to change the default palette. I'm sure there are other ways of doing it, but this is how I managed it.

Open up the file /opt/retropie/configs/all/retroarch-core-options.cfg

Change the following two lines in that file from whatever they were before to read as follows:

nestopia_palette = "cxa2025as"

fceumm_palette = "sony-cxa2025as-us"

There doesn't seem to be any way to change it for Quicknes that I can tell. When you go into the Quick Menu/Options screen while inside a game in the RetroArch menu, instead of seeing the various options such as a palette selection like in Nestopia and Fceumm, all it says is "No Core Options Available".

I'm going to tinker around a bit more with it.

Good news is that there seems to be an "Overclock" feature in Nestopia. I don't know if it will do the trick, but there are a handful of games that wouldn't work in Quicknes that have some audio stutter in Nestopia. Maybe I can fix these by making individual game options for them.

In case anyone cares, those individual game options settings are saved in the following directories after you create them:
/opt/retropie/configs/all/retroarch/config/FCEUmm/
/opt/retropie/configs/all/retroarch/config/Nestopia/

I'm getting obsessed with this. The closest to the real NES via composite (NES can't do RGB without replacing the PPU chip on the board) is the PVM style. The brown on SMB is more "alive" than smooth or composite direct.

As a reference I'm using an NTSC console connected to 21" a curved Sony Trinitron, recapped and on totally default values. Pictures are useless I'm afraid, the comparison is only possible via naked eye.
