You will find eight folders by Jimbuna with tons of WW2 music. Only some of it is German, but there is more than enough there to keep you entertained for the entire patrol. Don't worry that it's the SH3 Download section - they use the same type files and are interchangeable.
Free Cam: Nothing I can do to help you there.
German Speech: In the other thread in the Fleet Boats section I gave you the link for the SH4 Das Boot Sound Mod. It's a corker!
