I checked the "Run in 640 x 480" screen resolution" in Compatibility Setteings and that worked for me.

Using Windows 7 64bit

Create a file called player.ini using Notepad. It shoud contain (between quotation marks)
"0 BaseCMO.cmo" as the first line. (caution: do not save as a txt file)

That's it!

Save this in the same directory that conatins Game.exe and Syberia2.exe.

PS roll back all the compatabiltiy nonesense you did for game.exe and syberia2.exe. Just gives you gray hair.

That's funny. As if GOG is a perfect system with zero problems.

They're a great company with a great track record, but being shocked at there still being problems in a product like this is comical. Things slip through and they can't control everything.

When I run the game I get a black screen, but still got sound.

What worked for me was to "Alt-Tab" out of the game and then "Alt-Tab" back in.

Then the game worked just fine.
