Seems Amazon changed some more things in the whole structure. Installed "successfully" my localisation of 3.3, which I amended with the given details above for compiling.
Result: a mixture of english and german, menu (after pressing the button) invisible but "working". So, if you know how often to push the button down, you end up in the choosen menu, but this is not the aim of the game.
Actually I will definitely NOT do an update of the german localisation for 3.4. Too much nittycritty work I am not motivated to do. Sorry ...
