Right now I am running GOG Galaxy in bottles and it is mostly stable. However, I don’t like how GOG Galaxy constantly is showing ads and harvesting data.
What I am looking for is another Windows launcher that can manage GOG games. Ideally it should be simple and work with a controller.
I also need an alternative to the cloud sync. I think it might be possible to either use Syncthing to sync folders or to setup a network share and then use some scripting to save my progress once I’m done playing. The biggest issue I have is that I don’t know how to import my GOG cloud saves into the offline installer.
That will depend per game as far as I know.
Native vs wine/proton locations will vary and even when emulating windows some games use “My Games”, “My Documents”, %APPDATA%, etc for the save file location.
