Eleondor, no, development started with studying the executable file of Heroes 3. There were no source codes, and there still aren't any. zoog, I've already implemented support for numpad in my version; I just need to send an update to Baratortch so he can include it in the next version of the HD mod. Also, I have some ideas for a new mod with a bunch of extra hotkeys, but it's still in a raw state, and I haven't had the time to finish it. And doesn't Esc work in all the screenshots? When I play, I use it constantly.
