In February of '97 Lucas Arts released a patch called Yoda Update #6 that fixes problems in some zones. The Patch is a self-extracting archive that replaces the main game data file
Yodesk.dta with a new one.
The original release notes of
yopatch6.exe have been preserved by the Wayback Machine here (and with a different design here). They claim that in addition to the zone fixes "minor art modifications" have been made.
It would be interesting to find out what exactly has changed in the newer data file.
