LSU sound fonts

Hi guys
I assume this is covered elsewhere but I couldnt find it
I am looking to change some of my fonts on an obsidian V3
I installed the program on my PC
I downloaded all of the soundfonts (zipped) that Ultrasabers provides
I unzipped folders
I linked my saber (that wasnt easy and took maybe 20 attempts)
HOWEVER....the program asks for config files and all the fonts are LSU files.
Do i need to convert them or just rename them or other?

Cheers in advance

Oh and if anyone has recomendations for setting up motion etc then that would be nice. My saber seems to make the flash on clash sound about 10% of the time just while swinging

ADDITIONAL

I think I was being a dummy regarding LUS files....please disregard
Recomendations is still valid though
