Mccoy hi.
I'm not using Howard's wrapper, however here is an alternative I'm using. As you already know, Mamewah has a new feature to use specific game config so all you have to do is setup a different ini for each game.
I know what you're thinking, too much work to setup 72 game inis. For that I've include a vbs file that generates all the game ini's, just edit the CreateIni.vbs for the appropiate directory paths. Of course, I'm assuming you already know the basics to Zinc configs.
To execute the vbs file, just double click the ReadFile.vbs and that's it; all 3 files have to be in the same directory: ReadFile.vbs, CreateIni.vbs and Games.txt)
Hope this helps.
Cheers,

Congui
