What class of sub are you in?

In any case, I don't know why ISP would cause this. I didn't touch the sound gear or sensors. You should start a new career/campaign when installing ISP. There are changes to the crew abilities/rosters that could cause problems otherwise.

It looks ok, but I did not test a lot of extra mods when developing the TMO versions. Did you start a new career when you installed these mods?

The UPCLocalization file has the text displays, but does not effect operation of equipment. I did change that file to display notes about the special abilities, of course. I don't recall making changes to the UPCUnitsData files.

Tbh, I've already forgotten a lot of the details of this stuff. You can open the *.cfg and *.tsr files with Notepad and make edits.

Maybe I used the same UPCLocalization file from the RFB version, instead of making a new one from the TMO file. This is the only explanation I can think of. If you uninstall all your mods, then make a copy of the TMO UPCLocalization file, you could hand edit the changes regarding the 'special ability' notes from ISP, then put that file in the ISP mod.

Since I've never played the German side of SH4, I don't see myself as the one to take on this task. Besides, there are still things I would like to do for the RFB side of things.


On a related issue, I am coming back to base from a first patrol in a Dec. 2 '41 career (S-class). It has been a truly miserable experience. Most of my patrol time has been in 15 force wind. The weather hardly changed since I started, and has ruined my patrol. I found I was not able to move on the surface, and had to resort to submerged travel. You can imagine how slow this was. I have stuck to my house rules regarding TC, length of patrol, etc. Oh, I forgot to mention, I haven't seen a single ship, since leaving Manila.

As I don't wish to ever have another such patrol, I am going to take another look at the scene.dat file in ISP. The weather in my tests was never this bad, and I think I need to dial it back some. This is my next priority.

Sure.

First, I have all the realism options enabled, except the external cam, and I never use it to cheat. For me, it's more of a boredom combating device. Much of sub patrols are a waiting game.

1. Dead is Dead.

2. Orders are orders. When I get a mission to patrol area X, I go there and stay for at least a week, and maybe two. If historically, it was a tactical deployment (i.e. the defense of the Philippine Is.), I consider one week enough, if it is in the nature of a strategic deployment (i.e. commerce raiding), I'll consider it to be a 2 week order. Some discretion is needed here, as the game missions may not always make sense in your situation. For example, if I were to get orders that were suicidal (recon of major enemy base), or just plain stupid (go far away, where you won't have enough fuel to do squat), I ignore/modify them.

3. I limit myself to TC of 32x on surface, 64x submerged. The reason I keep to a lower value of 32x on the surface is that the wave mechanics are mostly negated above 32x, so speeds change a lot between 32x and 64x+, when waves are large. Because the weather was "stuck" for so long on this patrol, I was going to 64x for part of the nightly recharge; otherwise I couldn't get anywhere. I hated to do that, but I had 16 consecutive days of wind speed 15, and it was far worse than anything I had in tests of ISP.


4. I don't use the TDC in an S-boat. That is apart from using it to set a fixed gyro-angle. Manual calculation substitutes for mechanical wizardry here. On this patrol it didn't really matter, as I have yet to see a single contact. :O:

5. I am using a mechanical reliability rule scheme, sort of like the Ted Healy system, but somewhat more detailed and elaborate. It is still a work in progress, though. The only issue I rolled up in this, so far, is a potential gun jam, but again, since I haven't fired a single shell, it doesn't really matter on this patrol.

6. The patrol is limited to a reasonable time. I figured I loaded 45 days of food at the start. I had planned to go back to Manila to top off my tanks, and replenish, but as events transpired, the storms prevented my from getting back before the Navy destroyed the fuel stocks. Bad for me!

Reduced compared to what?

ISP versions 2.15, 2.4, and 2.6 should give identical diving performance. The versions before v 2.15 were developed on a different theory. I briefly "tested" TMO alone, but I don't recall diving times or such.

The whole diving performance business is more complicated that just increasing or decreasing diving times.
