Go to options then settings. Select Jabosdirect3d8. Then go to options then configure graphics plugin.
Change the Full screen resolution to any size but it has to be 16bit not 32bit.
Also use Legacy pixel pipeline and Direct3d transorm for this game. To do that go to configure graphics plugin. Untick hide advanced settings. Then go to the advanced tab and tick the boxes i mentioned.
Now you can enjoy this game without some of the background being missing and with no flickering!
Edit : Sorry about the delay. 10 mins....lol!
