Hi Again Monty.
I may have given up too soon.
Click once on the downloaded TheGame.zip file to highlight it.
Press the Command⌘ + I keys, to Get Info.
Change Open With to Stuffit Expander.
Double-Click on TheGame.zip.
A folder titled TheGame will be created. Open that.
In there will be:
decks An Empty Folder
Game.jar
game.xml
images Folder This one has many sub entries.
preferences.properties
readme.txt
release_notes.txt
runme.bat
When I Get Info on Game.jar, Open With is set to Jar Launcher.
That's as far as I am going though. does that help any?
