Hi Hesiment
Sorry for bad install instructions, it is my fault with time etc.
Right follow steps as below.
1. Place Submarine, library and Zones cfg files into your normal sh3 directory in program files. (I think you have done this already).
2. Now open up your SH3 commander folder and copy and paste the two files (crew fatigue models and Medals and renown) into your sh3 commander CFG folder (confirm overwrite).
You will need to get the fix file at the begining of this thread and also copy that into the same place as it fixes a small bug.
3. Now when you run sh3 commander you should go to time compression options.
Scroll down and ensure that the option of (When in 3D views) is set to 1024. This means that anything on or below this number effects the fatigue model and any time compression above pauses it.
It is called 3drender in the actual file but sh3 commander changed this to avoid confusion. I just forgot to mention it

my fault.
When you then go to the available fatigue models you will see the Holl compatible ones.
Any more probs give us a shout.
Sry for trouble
