Thanks guys.
I read the forum before posting and know NOT to post the actual cheats.
Of course, they're easy to nab as we're all aware:)
Yes, I realize 'DAN' is a sequence and I've tried upper/lowercase combinations with and without a period @ the end of the string on my store version and no dice.
Regards the Sierra updater, it still updates my version meaning yes, the patch mechanism does work. What craps out is the missions upgrade. A new executable is dropped into the '~' directory I specified and if I interceed and run the exe, the missions are installed. Seems like the updater deletes the files in the directory then tries to run the executable.
Kudos for Sierra offering an update, however stale, 7+ years after the game was created. Kooties to them for breaking it:)
