If your game is functioning normally, follow these steps. Note that the menu icons are universal, so even if you can’t read the text, you can navigate by shape:
Go to: HKEY_LOCAL_MACHINE \ SOFTWARE \ WOW6432Node \ 2K Sports \ NBA 2K11 .
Navigate to your NBA 2K11 installation folder.
If you're still stuck, use a translation app on your phone with "Live Camera" mode to read the menus in real-time until you find the "Settings" (Optionen/Opciones) gear!
