Wellllll.... the menu icons are combinations of "pictures" that are pointed at by the "menu_1024_768.ini" file, which is a very scary part of the game to be noodling with, not only for that particular file, but also for the method of pointing at the pictures. I'm really not "qualified" to comment on doing much in that file, other than maybe causing a CTD... CapnScurvy is our "Resident Expert" on that file, but is very busy right now with further FotRSU updates. Maybe in a few weeks / months one of us will have time to look at GFO and see what you're referring to. That particular "Radar On / Off" button, by the way, is really the "Snorkel Up / Down" button in the Uboats, and was probably displayed differently in stock, hence the difference in GFO.
