How do I make characters for Hit&Run

I want to start modding hit&run by replacing homer with Beavis or Butthead from the show Beavis and Butthead as a playable character mod and I wanna know how I can do that and also maybe the voice lines too

There are plenty of tutorials about it, such as this one that might help.

Thanks

K so Im watching the tutorial and im stuck on the blender part he imports the model with something that I dont have in blender and I tried checking if there a tutorial for it but there isn't I also downloaded lucas editor xml thing but it doesnt have a tutorial on how to set it up in blender
