Ah yes... Do you have Stock? If so, that's one of the frustrating parts of the game.
TMO2.5 changes some of the mission files up, as does
RSRDC and
Fall of the Rising Sun Ultimate. Download one or all three of those, and use a program like
WinMerge and / or
Notepad++, and compare the different versions of the mods against Stock in the "Data / UPCData / UPCCampaignData /" files of CareerStart.upc, Flotillas.upc and PatrolObjectives.cfg, all of which point back to the files in the "Data / Campaigns / Campaign/" and "Data / Campaigns / Campaign / PatrolObjectives/" files. All of those files work together. I will warn you right now, that if you go to changing anything, work on a copy, and make yourself a mini-mod (or mega-mod, as the case may be), so that you can back things off if needed. In stock, you should notice a difference between the missions when at a different home port. Pearl Harbor boats do Empire Waters and a few nearby locations, like the Marshalls. Fremantle boats do South China Sea, or basically anything from the Phillipines and South of.
If you decide to activate and play TMO, you should use the small patch:
http://www.subsim.com/radioroom/down...o=file&id=3506, but if you use RSRDC on top of TMO, you won't need that. No matter how you do RSRDC though, there is also a patch for it, which is listed on that RSRDC page link above. Just be sure that you read all of the ReadMe files for both of those mods, as well as the
JSGME documentation on activating a mod. The full "
User's Cuide" for JSGME is also available...
