ROM File patch and pin2dmd editor project for Stern Big Buck Hunter by Sharkky
To create the needed ROM file you can use bspatch (http://www.daemonology.net/bsdiff/)
Use the latest pin2dmd.exe tool to upload the palette .dat file with /b option.
(e.g. pin2dmd.exe /b bigbuckhunter.dat) and the latest firmware version to use the ROM.
You also need a to set ignore CRC in pinmame for the patched ROM.
For real pinball machine copy the .dat file as palettes.dat to the SD card.
