Actually there is an update. The torrent contains a rar file called of all things "Son of a bitch update 0.29 Update Only"THERE IS NO UPDATING BETWEEN .28 and .29 YOU NEED TO REDO THE WHOLE THING.
The code updates are all within the QSP file and all the updated videos (webm) and pictures are in their correct NPC folders - I have just checked. Size of the update is 1.19gig after extraction. Unless of course you mean save files which can only be updated once the translation mod is completed (Using it's save updater)
