It gives you the native aspect ratio with doubled resolution for each game, so = It doesn't look anywhere near as how it looked on the arcade machines. Have you ever seen arcade game with black bars usually left/right. I haven't. native aspect ratio is the correct display for the game as a lot of these games were stretched out and it was not the true display so=looks like arcade machine. as for your second question yes i have seen games with black bars left and right,on holiday in spain where they had arcade shooters like dodnpachi,super contra.....they should have tated those montitors.
