I would be nice to find un-used plug-ins and activate them. There are alot if configurations from Sh3 that have not been removed for Sh4. I would like another Help page when F-1 is pressed. There are so many available Hot Keys, it's almost necessary to note them somewhere. I added this one for functions that can't be found anywhere else.

There are several files accessed when a option page is selected. Several here:
C:\Games\Silent Hunter\Data\Cfg
Commands.cfg assign key functions and messages ect...
One here
C:\Games\Silent Hunter\Data\Menu
menu_1024_768.ini sets mouse locations graphic textures and such.
And here...
C:\Games\Silent Hunter\Data\Menu
menu.txt
It wouldn't suprise me if an extra page was discovered. One idea on how to find out is to advance the date, then run the game. Just double-click the time at the lower right on the taskbar on most Windows based systems. Don't forget to reset to the correct date when you are finished!
This will give you a clue as to what files are being used. Then one must experiment with altering these files and seeing how the game responds. Remove a block of lines then see if a button or page dissappears. Remember to back up any files in folders of a different location that match so you can keep track of all the confusion. Add your own lines to match how the original lines are written and the game may just add something new!
In windows explorer, or my computer, if you right click the right pane and select view then details, this will show date modified. Then push on the top bar "date modified" and it sorts all the files by this date.
I don't know if this will help you get started but it is one idea.
Another is to write a letter to UbiSoft. You never know, they may write you back with easy step by step instructions on how to make your own custom menu selections. Combine these two and you could actually find something most of us have not discovered!
