Except that would mean dealing with physical games in 2018, hunting down discs and controllers and memory cards in decent conditions, messing with ancient cables instead of standard HDMI, losing useful features like suspend, dealing with those old terrible loading times...You know what else plays all your favorite PS1 games and is just about as small as a psOne? PS2 Slim
