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

Well, that's a bit strange, Wizard said. Like, you can write an HDMod, but you can't compare text files. :)

In HotA, it's already set up so that all text files are taken from within the program, and external text files are ignored. It wouldn't be too difficult to add a similar feature to HD.
