German Speech Files??
 

The addon U Boat Missions for SH4. I have tried the Spaxs SH4 Uboat SPEECH FIX_V8a and the crew still speaks english.

Ideas?

It looks like the mod works from the remarks on the dl page.

Did you remove the mod from the zip, or rar, or 7z ?

The mod folder should be copied to the \MODS folder of your install from the zip or rar, or 7z it came in.

Its file structure should look like:

Silent Hunter 4\MODS\Uboat SPEECH FIX_V8a - if that's the mod name.

Enable with JSGME in port, then try it.

Hope this helps.
