I remember that the end of level screen was coloumed up and down for each player.. with multiple screens for the upgrading/lvling up of your character. i.e. i think the characters lvled up.
After looking at both d&d games and Knights of the Round they look very close to what I remember ... I will have to try them out.
For the longest time I thought it was like goldexn axe 3 or 4 but I was way .... wrong about that.
