I managed to get it running with VDM sound :Brain:
Just turn off everything under protected mode in compatibility tab and it works like a dream! Also, for sound, you need to add -a argument in run....
Then again, why am I writing all this, I'll just include the VDM config file
Copy it into 7 cities of gold directory and start the game with it! Btw, change the directories before you do! (right click -> properties)
