Need help on the following problems.

1 How to run the game in Full screen mode? Using game launcher to set it to full screen and still game go back to default.

2 Where is the save game folder?

%userprofile%\Documents\My Games\Skyrim Special Edition GOG

Find (line 44-47)

bBorderless=1
bFull Screen=1
iSize H=1080
iSize W=1920

in SkyrimPrefs.ini and edit to your liking. Remember to save.

Thanks for your help.

Anyway, managed to solve this problem. The cause is I have disabled MS OneDrive on my system.

I am trying to get MO2 to find my GOG version of Skyrim. MO2 is updated to the latest version and I have also posted the games_skyrimse.dll file (which was posted to Nexus on 8 Oct 2022 and is supposed to make MO2 find GOG version of Skyrim). The GOG version of skyrim is not on the list and when I browse for the game, I can only see the Data folder in the installation folder - not the .exe and other files See the attached screenshot. PS I have launched the game once.

I've tried MO2 version 2.4.4 with the original DLL and it had no issues detecting GOG executables (Skyrim SE, the launcher, and SKSE which I added myself). But it would not work due to bad folder name in the game plugin.

Try with the original DLL, if it does detect the game then I'd say the new version is still buggy. If it does not however then perhaps you pointed to the wrong folder? You need to enter the "Skyrim Anniversary Edition" folder but then a list of files is shown. Make sure you are not selecting "Data" subfolder when you press the accept button.
