That's a link to a nice generic BK.ini file. It has a lot of useful comments and empty stat spots, and no actual information. It's what I use as the base for each girl pack I make. Using a generic empty starting point is a lot better than trying to use an existing file from one girl for others. The latter way is going to end up with info from the first girl contaminating the data for the new girl.
At a minimum on any new ini file I suggest setting her name. The generic file has XXXXXX as first and last name. Replace these, or you will end up with XXXXXX as the name of girls in the game. Beyond this you do not
have to set anything else in the ini file. Everything else you set is extra beyond the name.
The reason I started using ini files, if only for the name, on every pack I make is because, without it, the game parses the pack's directory name to get her name, and this parsing is far from perfect, especially if the directory name includes things besides the girl name, like show name, or superhero name, etc.
One totally different tip is for fixations, personalities, and traits, avoid using the "always" stats unless you really, really really intend to make it happen for every single clone and unique of the given girl. In my entire 200+ packs In think I have set Always data maybe 2 times. One was mostly a joke (Ariel, the little mermaid, always has the trait "Always wet". And yes, I know that the meaning of the trait is not the correct meaning for her, but that's part of the joke.)
