I am also interested in getting it to work. I was able to get it partially patched up to work on Win10, but I still get a black screen at night. Is that what you experienced as well? Of course the game is unplayable if everything goes completely dark at nightfall.
If I remember right I could not start new game at all. It worked fine to menus and character creation screen but got black screen when game itself started.
I had a problem like that, but followed these directions here: http://telp.org/mm9/tavern/anyboard/posts/41508.html
After that, though, I still had a problem at nightfall, which remains unresolved. If I were not currently far into MM7, I would probably look more seriously at it, since this is the only MM game I have not given a serious attempt at playing. I know it doesn't compare to other MM games, but most games don't compare...I have heard that, technical issues and incompleteness aside, MM9 is not a bad game...just underwhelming considering its lineage.
