Current questions and answers regarding the map editor.

I have a question: I've encountered so-called map-mods several times, and unfortunately, most of them don't work on my version 3.0, but that's okay. So, as I understand it, players have created bosses there – probably monsters with high stats, and modified heroes, etc. I've also tried to do something similar; I've modified the entire data folder, changing everything for creatures/heroes, but fortunately, these changes aren't transferred to my maps downloaded from the internet because the map requests the specific game resources that are on the computer where it's installed.
Well, that's all the background; the point is this:
How can I make it so that I can transfer my "mods" along with the map over the internet?
Thanks in advance.
