HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Noticed that the processor no longer gets heavily loaded during loading and saving, but the processes themselves have become extremely unstable. Sister, maybe a little something to calm your nerves?

Added 1 hour and 43 minutes later
And also - is it possible to teach the mod to, when encountering matching save files, not overwrite them, but instead add a number? It would be convenient for future games.
