Yeah, if you place a new base the first thing you see is the "loadout" is grayed out, so apparently that's fixed, it's in the ammunition.upc file so whatever it says there applies to all bases. My "Gone Asiatic" mod edits the flotilla 2;

So instead of that long drag from Australia you start closer to the action. That's okay as far as it goes, but it would be nice to change bases and flotillas as desired to get a larger variety of missions/patrol areas. One possible hack might be to copy selected parts of the objectives, so (for example) flotilla 2 gets additional objectives similar to the ones from flotilla 1.

agreed
 

it would be great to get some of the fremantle missions in the pearl flotilla, and I'm thinking of trying to make that happen.
the only problem of course is the game decides what area to send you to, right now I keep getting sent to guam/saipan area, then maybe down to the caroline islands where there is very little sailing around. thats why I finally figured out how to edit the .mis files for jap convoys and task forces and add a little more to it.
right now my career is in late 42 and the area should be full of traffic because of the Solomons but there isn't. its like truk should be loaded but its empty when I sail to it.
I'm going to look into this idea and see what I can come with, if anything good comes up I'll let you guys know.:hmmm:

The thing about where the computer send you.

If I do not like a destination I pick my own, makes no difference to the game, its results that count when the medals come around. I was sent to photo Singapore once, I thought no way, I'll get belted in those shallows, so I went to Formosa instead (looking for the flying Dutchman) and got loads of ships!!!

:arrgh!:

Missing the point, skipping the mission objective is not a problem, the problem is you can't end a patrol without returning to the designated home port. What I'd like to do is put into any port to end the patrol - example home port is Pearl, I leave Pearl and cruise down to Guadalcanal and sink some ships, then instead of having to go back to Pearl I go into Brisbane and end patrol there.

Only hackable thing I can find;

\Data\Cfg\Basic.cfg

That has a datablock;

[TIME]
TransferFlotilla=1
NbDaysInBase=28
NbPatrolsInFlotilla=3
NbMonthsInFlotilla=6

I just edited that;

[TIME]
TransferFlotilla=1
NbDaysInBase=28
NbPatrolsInFlotilla=1
NbMonthsInFlotilla=1

So instead of needing 5 months and 3 patrols in a given flotilla before you're allowed to request a transfer, you should need only one patrol and one month to put in a request. Need to test it, since there are other factors involved - where when and if you can transfer is also controlled by the sub type and starting flotilla (example Asiatic start you have to go through the whole fall of Manila, fall of Java, retreat to Australia sequence before any transfer is possible) in other files, so we'll see if that improves things or not. Still isn't quite what I'm looking for, but might be the simplest way to add some variety to careers.

understood sniper, I was replying to part of sfc's post.

tried but no go
 

first try at making several ports as home ports at same time has failed, I could still refit but not dock even with flotilla.upc file edited to having 2 open at same time as home ports. this may be a no go but I'll keep trying.
