Well you can call me thick...
Ive only just had some time to look for the file to adjust the Random Values for Faulty Torpedoes and can only find 1 file for German Ammunition in the game and the Torpedoes section dosent have any Values for Dud, Circular Running, Early Detonation ect
Ive only found 1 file close to that and that is for the Torpedo Tubes to Jam & Chamber Explosion.
If you want to look for yourself this is the file path i have took.
C:/Program Files/Ubisoft/SH4/Data/UPCDataGE/UPCUnitsData/Ammunition
The one for the Tubes to Jam/Chamber Explosion is the other one called Weapons.
Both opened with Notepad. Any feedback will be great.
Dont know if i have missed a file but ive been pretty rigorous in my search.
Cheers
