Hey , I have GOG version too. GRM works for GOG and Horems UCP , he just made a compatibility change , which as soon as i understand what I am doing , i am sure it will work.
I think I need a modding 101 course lol. There are many files and I don't understand how the game picks up the modded files when they are named differently from the original.
letting you know we are out here with you . its a big galaxy.
Right now I am trying to combine GRM and UCP . Gauntlet and Horemvore have been very helpful. But I still lack understanding, I guess i will go through the files the hard way to understand what is what and why certain files are in certain places.
One of my goals is to become good enough so I can contribute
Have a great day
JJ
