I actually rewired my internal PC speaker to a big external speaker just so that I could hear the music/sfx of the game in all its glory.
And that awesome intro animation too - never seen anything like it at the time, like simply seeing realistic human faces being drawn in a DOS game was just mind blowing.
Best PC Speaker music ever was Xenon II, by Bomb the Bass[0] (which much later I discovered was a re-rendition of Carpenter' Assault on Precint 13 OST[1]).
May sound silly for some people today, but that was some incredible wizardry at the times, given the limitations (PC speaker was monophonic, square-wave only). As a YouTube comment says: "This is musical equivalent to pixel art."
it's the colour scheme that I remember most strongly. I still think "very prince of persia" when I see certain colour combinations, especially cream and purple.
Also, the steps, the gates and all other sound FXs.
Most people are/were fascinated by the fluid animations, but this game was perfect from every angle.
