This patch utility will update the Might & Magic III sound file for compatibility with the AV Macintoshes. When you run the patch utility, it will ask you to locate the Might & Magic III sound file. Select the file and the utility will update it. Because the utility will update the file directly, you should make a backup copy of the sound file before updating. In order for sound to work correctly, you may need to increase the memory partition for Might and Magic III. Before launching Might & Magic III, select the application icon in the Finder, choose "Get Info" from the File menu, and increase the memory by 100K or so.
