@bigbay you are welcomed.
If you need any help creating your own image feel free to ask here.
There are resources and options to build a gernan based image.
I.e. you are even able to set some arcade games from Atari and Capcom (Dungeons and Dragons, Aliens vs. Predator, Xybots,...) to german language.
Get ready for "Münze einwerfen!" :D ("insert coin!")

@horald:
Hi folks,

has been taken care of. You have to go through the menu item "Localization options/keyboard" in raspi-config. I only saw the first entry and then wondered what it had to do with the German keyboard setting, but the queries come after that.

Many greetings
Horst
