Thanks for this post. I had no idea there was a Das Boot sound mod for AOD. I thought that the OP was confusing it with the SHII mod.
I haven't played around with AoD in a few months as I'm on a modern sub kick at the moment, but I am going to take note of this post for future reference.
Very detailed and useful info on editing the game. I'm tempted to start a career in '39 with the the type XXI and a whole bunch of homing torpedoes. It's fun to go into "shoot 'em up" mode sometimes.
