Custom palettes for Game Boy gamesLink
The 'GB Colorization' core option must be set to custom.
Create a folder called "palettes" in RetroArch's system directory. Then, you can place custom palette files (.pal) inside the "palettes" folder
You can define different palettes for specific games by creating a .pal file in the "palettes" folder with 'INTERNALROMNAME.pal' or "rom-name.pal". If no specific palette is found for a ROM then the default palette is used.
You can also define a palette to be used for all Game Boy games by creating a .pal file in the "palettes" folder named "Default.pal"
Custom palettes can be created from the GUI in standalone Gambatte
