Ok, so I created this new file, FRONT_goodiehut, and I copied/pasted the original core goodie hut file, and removed everything, except the "first part":

As I think it is a reference for the other files, as the name of the files is irrelevent, it still needs to know what to look for, although I might be really wrong on this issue.
Then I C/P a goodie hut "block", to add to my mod.
Two questions, here: Is the "first part" indeed required ?
and
I figured almost everything, except the "liklihood" of the treasures to drop. What are the odds, and how are they calculated ?
