I tried to open it on my Linux box, but nothing would open or mount it.

I tried on my Windows 10 computer, and nothing would open or mount it, I even tried HFSExplorer and MagicISO with no luck.

I tried to open it on a an old MAC computer running Mac OS X Snow Leopard, and all I get is a few files in the main directory and a bunch of empty directories when using Disk Utility, I tried to convert it using the command line and hdiutil, but that did not help.

I think this is a bad copy.

BTW Mega Demo 2 also seems to be a bad copy.
