Creating AOE II DE User Interface

How( If it’s possible) can I create different user interface, cause I really want to give it a try or see what options are available to create a custom user interface. Please let me know. Thanks.

First you need to know what part of the UI you want to change. Main menu style? In-game command panel? etc.

As for how to make the change, you could start from downloading mods from the User Interface category. You could open their directories to view which files they replaced. It might be a code change, or a resource replacement.

In game command panel. I want to give it a try for what I may want to have.
