Check this for reference: http://en.wikipedia.org/wiki/Ad_Lib,_Inc. http://www.crossfire-designs.de/images/articles/soundcards/adlib.jpg (note the upper left of the card) This commit does not touch "adlib" and "ADLIB" uses! Also it does not update all the SCUMM detection entries, which still use "Adlib". svn-id: r47279
