Way to find what each BCSV file does?

A Question for Animal Crossing: New Horizons

Question Answered but Unsolved

This Question has been answered but no solution has been chosen. You can still post your own answer to help the submitter.
The BCSV files seem to hold a lot of parameters that one may be interested in changing. I was curious if there was a way to somehow find out what each parameter in each file does aside for painfully changing each value and testing in-game. I have a feeling it might involve going through the game's code, which I have zero experience with. Was hoping someone might have some ideas or knowledge to share on the subject.

    There is no definite way as the parameter titles consist of hashed strings (crc32b as far as I am aware), so direct reversing is not possible. Brute force and dictionary attacks seem the way to go, however some people already put some effort in it.

    Have a look at and especially the file as this converts the bcsvs to better readable formats while including some of the actual strings instead of hashes.
