ok,
this picture shows how it looks when i select fullscreen:
-i cant go then to options or shut down program upper buttons are located on buttons of option, and there is a lot of black space around...
i´ve made edit picture, add one more resultion 1600x1200 and check box, that you first select screen size, and second check box that made fullscreen from selected screensize
and at this one is when i choose the biggest screen size in emulation-i don´t want to see ugly windows things
