Go to the
Might and Magic series forum. Click the New Topic button there. It's above the list of topics and the page selector on top of that.
Since you've applied third-party patches, in GOG Galaxy go to the Installed section, then right-click each game and choose Manage Installation, then Configure. Uncheck "Automatically update to newest version", then click OK. Also avoid manually choosing either Check for Updates, or Verify/Repair.
Starting with MM6 onward, the games were made for Windows, so what was said about DOSbox doesn't apply to you. I doubt GOG Galaxy is the source of your problems, but if you want to do without it, you can uninstall the games from GOG Galaxy for starters. Then download and run the "Offline backup game installers" which you can find in
your games library, below the blue "Download and install now" button for GOG Galaxy. You'll miss out on tracked gameplay time and cloud saves for MM7 and MM8.
