I was indeed missing the VOICE pack (provided by Dorade). 18 years ago, when we made the initial patch, it was too big for the majority of users, ADSL was not there yet. Now a day, 130 MB file is just peanuts. Time flies...

PS: I just tried my game with the patches, but was not able to make it run properly on my Win 10 box. And I was too lazy to boot my Win XP box (yes I still use it). I just switch back to MM6 , which runs fine.
