You can start the game with Man and Ulm, set formations and scripting, then have the two test armies attack the same province to see the battle. Start a new game on the same map to try again or edit the .map file to try something else.
You can edit the map file in notepad to use any units in the game, any equipment, any experience levels, any summons. Unfortunately, the map command to set a starting spell is broken so you cannot make a spell usable from turn 1.
