You need a program called dat2, and write the dos commands in the window to create a new .dat file.i downloaded the dat explorer and imported the master.dat and now i can modify the text messages. however, when i'm done, how am i gonna turn this folder into a master.dat? i couldn't find that option in dat explorer.
You don't have to put your translated files back to master.dat, since the game reads unpacked directory structure with higher priority. Just put it in Fallout\DATA\TEXT\ENGLISH\DIALOG\ directory and that's it. This is also better way how to distribute your translation, uploading whole master.dat containing your translated files is both illegal and cumbersome. (the same goes for F2)
Can you elaborate, about the legality part?You don't have to put your translated files back to master.dat, since the game reads unpacked directory structure with higher priority.
