You will find what you are looking for in the History.txt file in the Space Empires IV directory.
quote:
Command Line Options:
Se4.exe "[Savegame path]" "[Password]" "[Player Number]" "[Mod path]" -nd
[Savegame Path] = Exact path to the savegame file.
[Game Password] = Either the game password if this is the host processing the turn, or
the players password if you want to launch directly into a player’s turn.
[Player Number] = The specific player number you wish to launch into, or 0 if this is
the host processing the turn.
[Mod path] = Override to the directory specified in the Path.txt file (this should
just be the directory name of the mod, exactly what’s in Path.txt).
You can leave this blank to just use the setting found in the Path.txt
file.
-nd = Optional flag which indicates if any error dialogs should be displayed
during the turn processing if an error occurs.
Note: To leave an option blank, just put two parenthesis with a space between them.
Examples:
Host processing the turn, with no dialogs.
Se4.exe "c:\program files\shrapnel games\malfador machination\space empires
iv\savegame\BigMulti.gam" "Master" "0" " " -nd
Player wants to launch directly into their game.
Se4.exe "c:\se4\savegame\mygame.gam" "mypass" "1" " "
Host wants to process a turn with an alternate mod path, and have dialogs be displayed.
Se4.exe "c:\se4\savegame\supergame.gam" "master" "0" "c:\se4\mydata"
You should check the whole history file though because there have been several tweaks in later Versions. Just search for the word "command"
