Failed to mention that, didn't I? I have 1.4, should work for 1.5 but I have no way to test that. I did test with TMO a long time ago in a galaxy far far away, don't remember which version.
\Data\Campaigns\Campaign\US_NavalBases.mis
and
Data\UPCData\UPCCampaignData\Flotillas.upc
are the only files involved, so anything that doesn't overwrite one of those should be fine. In fact IIRC the only reason Flotillas.upc is needed is to change the home port for Asiatic subs after the fall of Java from Freemantle to Phantom 42, so if you're doing a Pearl Harbor career you could delete that one. Even in Asiatic you could leave it out if you don't mind the long slogging trek from Australia to where the action is.
