First problem; the game froze when I was about to talk to someone. No biggie though, I ctrl-alt-delete my way out and restarted and it all worked on the next attempt.
But by god! Is that a human being or did my graphics card just crash??

IIRC Arena was made to run in 320x200 or some crazy low resolution so you could actually have colours. That does tend to make for inadequate detail. DosBox gives you some interpolation options that can make it smoother, but sometimes that just makes it look weird. You need to experiment with the scaling modes until you find one you like.
