GB Palette Editor


  • .gbp palette files were originally used for the Mister, and specify only 4 colors. Typically used for GB games.
    • The budude2/openfpga-GBC core is ported from the Mister, and is currently the only Analogue Pocket core that uses .gbp palettes.
  • .pal files are a format specific to the Analogue Pocket, and are currently only supported on real cartridges, no cores have added support.
  • The default values above are the "DMG Bright" palette from TrashUncle (in the correct order for .gbp, inverted on .pal).
  • Most .gbp palettes go from lightest to darkest color, and the .pal format generally goes from darkest to brightest. Swapping between modes will automatically invert the colors for you so the palette will look the same once used.
  • The LCD Off color (for .pal only) is usually set to your brigthest color or the same as BG3. For this reason, inverting a palette will invert the LCD Off color only if it is equal to either BG0 or BG3.

Select a .zip file containing your .pal and/or .gbp files. Each file will be converted to the opposite format, and placed in a .zip file with the same internal directory structure. Invalid or non-palette files will be completely ignored (and omitted from the resulting .zip).
