I got slaped in the face for mentioning this in a previous thread but please check this out -
http://www.subsim.com/radioroom/showthread.php?t=164798 I think it is a sticky aswell!
Incase you didnt know - Silent Hunter 5 come with all the stuff you need to edit the whole Game and a script debugger to check where you are going wrong. I know alot of you are just using Notepad etc but there really isnt any point - Just use the programs provided.
I have tried no end of mods and most of them are causing errors which you dont know about until you run the game using the information from the above thread. Please check it out for yourself before you all flame at me
You can actually edit files while the game is running, turn things off and on etc - Check what and why the devs have left some stuff out. You can edit the Terrain, add buildings etc, even edit the whole map - WHILE playing the Game lol
Dont forget you also get the Goblin Editor - this is a powerful piece of kit that allows you to look at the gr2 files, link files to nodes etc, edit the routes and waypoints of the animations etc etc etc - i have only scatched the surface of it but you can even load stuff in from sh4 (not tried sh3 as its not installed but i dont see why it wont work)
I think the possibilities are endless - imagine all previous versions of sh in sh5 - i think atleast the subs can be added but its way over my head lol
Dont get me wrong - i'm no modder, well not much anyway but i do like to fiddle and for me SH5 has been worth every penny, i know the drm thing is a nightmare and hopefully they will drop it but to have this much access to a game is worth the price.
All i want now is ducimus to work his magic and get some of the dials and buttons within the sub to actually work and i'm sure if he uses the supplied editors he will find it so easy

I'm currently working on sounds - i already have the radio operator comment when the radio is turned on
Anyway - i wish you all good luck
