For those more concerned about presentation, the game has several options including video processing to smooth the pixels (my personal preference is to turn this off), and
scanline emulation is also available in 50 and 100 % options.
By default the games are emulated with a slight smoothing filter applied, to take the rough edges off the pixels that would have been smoothed out by CRT televisions of old, but you can also run them with «pixel perfect»
emulation if you choose, or else apply a slightly heavy - handed CRT filter for some real
scanline goodness.
