DMG is an exclusively Mac OS X file stuffing format created by Apple to run the carbon applications. It will not work when run in native OS 9 mode. It will run in the Classic layer of OS X, or in OS X native.

Sorry all you OS 9 users...you are going to have to get OS X Jaguar to access these files. The upgrade is dirt cheap at about $129 or you can be a bad little pirate and try to get it for free. Whatever, but remember big brother can watch you and fire you into jail or give you a big *** fine.
