Hi Shep,
Wow! That's an oldie but goodie!
I checked my old Win98 machine upstairs and I don't even have it (those HW Scenarios) there. That machine has WF version 1.03 loaded on it.
My main computer has versions 1.04 and the current 2.02. The current version goes back to 2014 I believe.
I remember that HW conversion thing from long long ago when you still needed the CD in your drive to run the game. That whole thing using the CD was done away years ago.
I want to say that the HW mod was worked on by Craig Foster and/or von Neimack who were both heavily involved with the Campaign Series before it was purchased by Matrix Games. That's circa 1990's!
Just a thought, you might want to see if "Game Squad" might have that download in their archives. They had some pretty off the beaten track stuff in their archive as I remember.
Other than that I wish I could have been more help. Good luck in your search!!
John
