About Traits, I have the list but beside each section there's no description. Each section title is well translated in French.
The skill section of the data.000 file in the save folder contains descriptions. It may be possible to replace that whole section of the file with the corresponding section from a French save.
Do you mean it's possible to do text edit of this file??
About data.000, I tried it and yes it's related to traits but if I replace it it seems that most of my game is reset, I keep inventory and other stuff but not character attribute for example, perhaps I haven't done well the test.
I suspect it's something related to male/female. Something that doesn't exist in english version but in french version. My character coming from english, in french this character is neutral and traits aren't found. But you could be right it's possible that for some obscure reason indexes are used for traits and are different for the french version. It's funny that the game manage that
There's probably no solution appart a binary editing (that nobody can do). From time to time, I quit the game, put the save in english version and launch the english version to see the traits.

Not very cool but better than nothing.
If I have the courage I'll try to create a new game in both versions with same character, do nothing, save and compare files. But well I doubt this can lead anywhere.
EDIT : I gave a try to binary compare data.000 files of a new savegame in both versions.... Well too many differences and tool not very powerful, giving up, just cross my fingers that I won't be stuck because of this savegame migration. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
