Should an emulator always display it's output at the complete size of the screen?
And let's say the emulator has a screen of 256x256 of which 256x224 is visible, should then only the visible area always be stretched to the size of the screen, or the whole 256x256 screen?
I'm guessing it also depends on the used monitor/video hardware of the original machines (arcades in my case), but is there a general rule of thumb?

It depends on the video hardware and the monitor (and monitor settings). Pixels can have any aspect ratio, but almost all arcade games use 4:3 monitors, so scaling to image to a 4:3 ratio is correct for almsot all games.

That's kind of what I thought and what I was intending to do. Just needed some conformation, thanks!
So generally speaking arcades don't have borders like old home computers, right?

Yes and no -- some systems may have them, but the operator is expected to adjust the image so they disappear.
