aspect ratio, maybe it's called? I tinkered with the fullscreen resolution option in the graphics plugin settings, and that doesn't seem to change it much. Whenever I fullscreen Paper Mario, it gives me an okay sized area of the game, but there exists a black space of about 1' inch between the edge of my physical monitor and where the game's space begins. I am playing the Paper Mario rom, but I'm pretty sure it has nothing to do with the full screen ratio issue.
