Use this thing:it's from the community wiki:
Getting Extra-Renown (Hacking)
Go to that career and open both patol files. One will have the renown for the last patrol at the bottom, lets say you got 1100. Add 30000 to that so it says 31100. Now the other patrol file at the bottom will have your total renown, 9000. Add 30000 to that so it says 39000. Save both but be SURE you ADD the SAME exact number to both patrol files, that is the key.
You also have to be in port or else it will not let you play the game and crash at startup. And the place where you edit it is in My Documents. It will say SHIII and then go to cfg. and then Careers and then your career name and then go to something that says like Career_0 and then it will say renown a little more than halfway down, and then edit it to how much you want. Then when you start it up you have to start it in the save that says, "In Base After mission" or you won't get your renown for some reason.
(copied from [FOX]Bort and Wulfmann posts from subsim forum)
If you load the save that says "In Base Before mission" you only need to edit a file named Patrols_0 Simply change the DeltaRenown value EG DeltaRenown=150.000000 will give 150 renown
