Just found out my second hand bought lightsaber is a Proffieboard

As you can read from the title my “new” lightsaber is installed with a Proffieboard and this is my first time seeing any of this stuff, I am looking for any help with installing fonts or sounds. LIterally all help is appreciated, any tutorials or guide are welcomed
