You would have to go into the encypted files ( this is possible ) and translate all the information contained in these files to german. the key word and sentence files could all be typed in german, that would allow you to get responces in german but unless you translated ALL the brain files in the 4.o I don't see how this is possible. It would be a lenghthy process and Probably would be wraut with errors. you'd have to be VERY carefull and not disturb the scripting surrounding the vocabulary. teach it german responces and override as much english as you can, it will however, revert back to english when it cannot find a responce to something it does not know. this would be easier with the 3.0 version but then again you will spend many, many hours working on this project. I may be wrong, as i am not a programmer, but i have spent many hours working with the hal program, good luck with your project. work on it. I can tell you how to view these encrypted files, I have been working with others who are intrested in this program. We have discovered many things about it.
