This is a link to my BOTN Incest Patcher.
Source is included.
There is a readme.txt with full details about the tool and it's options.
This will restore incest to the game.
In general, you run this in the root folder of your
Breeders of the Nephelym install (where Radiant.exe is) and it will patch the game. It will make a backup of the binary it patches (Radiant-Win64-Shipping.exe) and can also reverse patch (details in readme).
Updated for 0.752.4 (Early Build) (note, the previous build 202104092150 can patch 0.752.4 just fine although it can't identify the version so it's slower).
