Modding, copyright, and related issues.

So, you were digging around in index.bin, which is where new slots for creatures are added. Otherwise, neither the map editor nor the game will recognize the new creatures (I wanted to create a mini-mod for myself that would restore the Black Knights, and it simply didn't work without the index.bin from ncf).

index.bin seems to be something different; it stores information about resources created through the extended editor and is responsible for displaying them when the editor is restarted. The default index.bin also handles the display of developer objects in the editor, and the ncf version, I think, handles the display of new creatures in the tab that allows you to place them on the map through the editor. The NCF core itself is an executable file in which the constant responsible for the number of creatures in the game has been changed (by default, this is 180, increased to 1000) + the Creatures.xdb file has been modified.
