NES Custom Palette Preferences?

I mean within a Retroarch installation.

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.

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?

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

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.

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.

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.
