Absolutely. And now you see here why. It's because of war in Ukraine, as Verok is ukranian.
You can read more about it, on his blog.
But, apart from this. There's nothing left from the original content, no game patches remained.
So where to get them? I don't know but you can get following mods/engines to play Heroes in FS
Heroes IV
- Equilibris 3.6
- Ultimate Heroes IV by Nimostar (which is using original Verok's patch)
Heroes III.
- HD Mod + Mods which are incorporating it, like HotA or ERA
Heroes II.
