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
The Gambatte core has the following option(s) that can be tweaked from the core options menu. The default setting is bolded.
