NHF – new heroes for Heroes V 3.1.

There are many features besides Talkbox that are only available in 3.1, and it is impossible to implement analogs of these features using 3.0, which means that many of the mod's mechanics will break or become, in principle, impossible to implement. Therefore, there will definitely be no transition to 3.0. I advise you to pay attention to 5.5 if you really want to play with advanced AI.

@Gerter, if you are talking about the fact that the AI of the esteemed Quantomas works on 3.0, then no - it's on 3.1: https://www.quantomas.de/downloads/ (there, apparently, are his executables along with a custom campaign from foreign guys). I'm not really in the know, but I can assume that he initially had a 3.0 modification, and then he somehow updated it. By the way, it says there that MP is not supported.
In general, I wanted to install his AI and NHF, but NHF turned out to have its own executable. What a disappointment Maybe someone can share information, please, about what is in the NHF EXE? Does it contain something critical?

PS: and, by the way, @Dyrman, how did you create your executable? Does it involve some kind of binary replacement of values?
