Apple wants a partition type "HFS" which is their disk system. Having one makes
your CDROM appear natively: icons, window placement, file type/creator codes
all that stuff is embedded in HFS directories. Many hybrid CDs (games) have
separate HFS and ISO-9660 dirs, and the Mac user sees the HFS first, or
sometimes both.
But there is also an Apple extension to ISO-9660. It's described in this
ancient tech note from 1989.
http://developer.apple.com/technotes/fl/fl_36.html
Since HFS files have a second "resource fork" they use the ISO-9660 "Associated
File" bit on a second file with identical name. Other HFS details are stored in
the Apple extension record.
To see ISO-9660 the user does have to turn on "Search For All Volumes And Mount
Them" or something in some control panel, to ensure that plain ISO-9660 show
up. If the user has had one before, they're probably set.
