Difficulty level in AB and RoE.

In Campaigns, the difficulty level is fixed and cannot be chosen by the player. However, there is one way to change this. You need to open the game archive (using ResEdit, for example) and extract the .h3c files – these are the game campaigns. Open them in the campaign editor and check the box labeled "Scenario Difficulty Level Can Be Chosen by Player" under "Edit/Campaign Properties." Then, repack the files back into the archive, replacing the previous ones, and click the MakeChange button. The program for opening the archive can be found here.
