Study how SH4 transfers the Flotilla home base at Manila, Philippines to Surabaya, Java, and then down to Fremantle, Australia at the beginning of the War over a period of a few months on the US side.

There are other examples; some mods transfer the Pearl Flotilla to Midway, and then later in the War to Guam, etc.

You'd have to edit the *.upc files yourself to begin your patrol at one Home Port (base) and end your patrol at a different/new Home Port and know the time-frame that you wanted this to happen.

With transferring the home base using the Phone, the first patrol out would be to a patrol area that would typically be assigned from your former home base. The way to work around this is to plug in a different mission ID number to get a patrol closer to your new Home Port before you go out on your patrol.

You would need to make a database of the missions and their ID numbers which isn't that hard, it's just time consuming, and edit the ID# change to your in port Saved Game file that keeps track of what your next mission is.

Happy Hunting!
