Export tool for what ? I have already described that backing up certain files (sh5.exe and a couple of others) and de-installing TWoS will give you the files you need to re-install game and using these files, this will give you a 1.2.0 game which is fully moddable and the TDW patch already applied.
Well, you still need TWoS for all that...
And all this for what? Just to play the 3-circle torpedo firing again, to see Captain Ralph in the initial tutorial, or playing with the mischief tonnage bar?...
No thanks!
