Rialmwe: I prefer not to have this update, I don't know why I can not to play with the analogs like I could before. Is there a way to stop GOG Galaxy reminding me of the update?
In my case It worked very well before. (Maybe I change the keybinding to work like I wanted )
I don't own the game but there is a way to trick Galaxy into thinking the game has been updated. In your game install folder you will find a file called goggame-xxxxxxxxx.info (with x being the game id number). This file contains everything Galaxy needs to start the game including the so called "buildId" which is a specific number. All you need to do is to change the buildId to the buildId of the current update and Galaxy will think that the version you are running is the actual one. To do this in a proper way I'd suggest to do the following:
1) Update the game to get the newest buildID or ask someone here to give it to you. Note it somewhere.
2) If you updated the game in step 1 do a rollback to the version you want.
3) Close Galaxy.
4) Edit the *.info file and change buildID number to the new one.
5) Move the game installatrion folder (or rename it so that Galaxy does not recognize it).
6) Start Galaxy (game should not be shown now).
7) Move the installation folder back (or rename it back to the origibal name).
8) In Galaxy press the gear icon -> add games & friends -> Scan folders for GOG games. Browse to your install directory to import the game with the new info file into Galaxy.
Now you should have the old version and the update message from Galaxy should be gone because Galaxy is thinking that it already has the newest version installed. However this will only work as long as there is no other update - in this case you would have to do the same procedure again.
