I bought this game as a new release and had all the expansions but in a move I lost them all. I found some old mods that I used to use. One of them was a modification of the racial .2da file to remove the ECL. I tried to apply that mod in my current GOG version and I get errors with it. The pictures of the subtypes I modify disappear. How can I apply these old mods to the .2da files in data area?

Any modifications you make go into the override folder.
