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

I have compiled templates for the Packs folder (located in the HiRezData folder) that will be displayed in the drop-down menu. To launch the game, use the setup program, select a template, and click Apply and Launch.
List of templates
#Default - standard set of 3DO templates (built into the game)
2SM4d(3) - templates frequently used in tournaments
2SM4d(2)

I have specifically arranged the templates in the order shown. This is the order that I find most convenient. It is best to add the folders from the template archive to the Packs game directory one by one, and in the order in which you want them to appear in the drop-down menu in the settings. If you extract all the folders from the archive at once, the drop-down list will be in alphabetical order or some other order.

baratorch, don't forget to fix

[+] two [OK] buttons in the hero encounter window:
pressing the left button ([Esc]) keeps the focus on the left hero,
pressing the right button ([Enter]) makes the right hero active

So that pressing the right button ([Enter]) makes the left hero active (as it was in SoD).
