Here is the working polish translation/language for System Shock 1 Enhanced Edition.
All files must be copied to res/data directory at System Shock 1 EE catalog.
And in the options you can change resolution to widescreen or at least 1024x768.
Enjoy and spread to the World!

Does not work, lack of Polish diacritics. Tested with 1024x768 and 1280x800. However, at 800x600 everything is OK.
