What i did was get out of port then save then load up as normal then GIS launched I Exited and then opened up my Mycomputer/programe files/ sh3 gen/user data then use the map by frist adding terain then ports and then slowly selecting the intel that i wanted to see. It was very easy to use and found it a great help on the intel front. Would it be when you have finshed your patrol to see the course that your boat took on the map? This would be a good for planing future patrols by using pasts intel.
One thing i did notice was that when you selected the submarines tab that it did not add anything to the map. This might have been because of the lack of AI subs.
One last thing though would it be possible to add rings to the map to show the air coverage?
But all in all it is a great addition to your great mod sir and runs very well and easy to use once you get the hang of it.
