>> If you want to use the English scripts instead or Russian scripts replace the original tombPC.DAT of the
data folder with the one in the main folder.  

>>If you experience problems in Windows XP, run this game in compatibility mode. 
That is, right click the tomb3.exe file, choose "Properties," then "Compatibility," and select "Windows 98/ME." 
This seems to solve the problems of having to double load a save file.<<
