Language change for Unreal Engine Games via trainer?

[montcer9012]

That was my first try, but this game have subtitles embedded to sound files.

That means:
1. Need to unpack the .UPK files, which i can, but can't repack it after; haven't found a proper tool.
2. Even i found a tool to repack BAO .UPK files, i need to unpack/repack the sound files in order to get the subtitles files and make any change i want.

I will be ok doing all that, but need the tools, which seems no one wants neither have time to develop. Have asked for it here, on xentax, Gildor's... Don't know where to get it and i am not coder to do it by my self.

So, better way to get game use the language we want is telling him to do it, and that's why i think on a trainer.
