Hi, I would like to know if anyone knows, or knows the author of this update.
Because? In the CD version, an amateur translation of my language has been made, which seems compatible with this version.
But all that is added is in English. I would like to understand which files contain these new texts, so that I can translate them, and complete the translation also for the GOG version. Thank you so much I wait for news.

Are you talking about Sfall or the game itself?

Sfall is developed on github https://github.com/phobos2077/sfall. They only ship english translation (https://github.com/phobos2077/sfall/blob/master/artifacts/config_files/Translations.ini) currently, but I think they would accept an additional translation if you were to submit a pull request.

If you wish to update game's translation, you'd have to do that manually checking msg files in data directory.
Alternatively, some translations of games and mods are going on at BGforge: https://tra.bgforge.net/projects/fallout/. You could see if it's already there, and if not, ask on https://forum.bgforge.net to add it, then translate online.

Thanks so much! I'll take a look!
