Dungeon Siege gave me a similar problem. A loooong time ago a forumer sent me this and it worked. If you have Toast, you might give it a try.
I copied this straight from my e-mail copy I saved. Of course switch out Dungeon Siege stuff for Chessmaster stuff. This may also work with newer versions of Toast.
Here is a link to the original post although instructions were sent to me via e-mail and copied below.
------------------------
Okay, here's the skinny... the following is assuming you installed Toast 6 Titanium into your /Applications folder.
- From Finder, navigate to /Applications/Utilities and start Terminal.app
- I installed Toast 6 Titanium into my Applications folder, so my directions will reflect this
- in Terminal, execute the following command:
$ cd /Applications/Roxio\ Toast\ 6\ Titanium/Toast\ 6\ Titanium.app/Contents/MacOS
(Note: you will have to escape the spaces, which I have done above, so you ought to be able to copy and paste)
- now execute the following:
$ sudo ./TDIXSupport ./TDIXController.kext/
(Note: you will have to provide your administrator password)
- now execute the following:
$ ./ToastImageMounter ~/Documents/Dungeon\ Siege\ Disk\ 2.toast -readonly -hybrid
- you should see the disk image show up on the desktop and in the Finder, and looking like an actual CD icon instead of the "usual" drive image
- At this point you should be able to run Dungeon Siege.
Now you would think you could simply unmount normally from the Finder, but that's not the case. Doing so will result in the icon going away, but efforts to remount using the above commands will do nothing. Instead, you will have to manually eject the disk image when you are dong playing.
- from Terminal
$ hdiutil eject disk2
This assumes that the image ended up mounted as disk2. If not, you will have to figure out the appropriate disk number. You can do so with
$ ls /dev
and looking for disk# entries where # is any number. Presumably it will be the highest numbered disk# entry
And that's pretty much it.
PS - For some reason, the disk doesn't mount properly when you try to use the menu option from within Toast 6 to mount toast images. I read up on the help docs for disk copying and it says it doesn't copy copy protected portions of cd's. I'm guessing it might but tries to avoid mounting them unless you do it manually like this.
