I have created the interface, so that is all completed

All right I want to start with making a modding application for lets say "Dark Void", how would I go about researching for the offsets and making the application fix the security so it is play able when saved?
In my current save that I have on my PC which I am using to research on, I have '2550' tech points, know that in hex is '9f6' know, I have searched the save game and cannot find that hex anywhere.
