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.
Regarding cloud saves, Heroic will let you download or force download them. After that you would just need to place them where they are expected for the game.
I use Heroic on desktop and deck and am a big fan personally.
I can download them from GOG. How do I use the data?
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.
