 Plus/4 palette as RGB values

Hi!

Does anyone have the approximate Plus/4 palette as RGB vals, in text or binary form?
I need this for a little conversion-project on PC.
I found an old thread where this was discussed, and there were even some people who posted links to palette-files, but all links were non-working at this date.
So if you have on of these files, please post a link to it!

Save a screen shot from an emulator, and you'll get a full colour palette

Yeah, it would be possible to extract it manually that way, but it would be much easier if someone had a complete palette, with all colors in order etc.

Are you referring to the old thread about p4fliconv, and the palettes posted there ? If yes, I still have them, and I can also post the actual formulas used to calculate the colors.

Here is my palette for both PAL and NTSC mode, in decimal and hexadecimal format:

http://www.sharemation.com/IstvanV/plus4/p4pal_ntsc_dec.txt
http://www.sharemation.com/IstvanV/plus4/p4pal_ntsc_hex.txt
The files were generated with the following simple Python script:

It can be easily modified for different brightness/contrast/saturation, output formatting, and also the luminance/color phase constants (which are based on the TED documentation, but I changed some to be more consistent with the real machine) can be adjusted.
