Choose an humongous installation to have all the Fallout files.
If you don't have everything, extract everything from critter.dat and master.dat with the Dateplorer by Jab for Fallout 1 or by Dims for Fallout 2 and put those into the Fallout\data folder.
Everything in data\text can be opened by the notepad.
There is also the .bio files from data\premade. Those are the bios for the premade characters.
There might be other files that might need to be translated, but once you did data\text, you have done 99% of the job, and it would be easy to check what is left.
