Hi,
No, I couldn't run zip files via unzip.exe since after launching a game the screen turns black and then goes back to mGalaxy, having Winvice running on background (doesn't happen by running Winvice outside mGalaxy).
And yes, same problem with both servers.
Anyway, I guess there is something wrong with Good64 romset, since i found on past messages someone having the same issue.
I fixed this by dropping the database and choosing other romsets, but maybe for future versions a check on this issue may help others.
Thank you for your support!
Gianluca
