Dungeon master nexus

i am a MASSIVE dungeon master fan, thats the main resson i got a saturn was just for the saturn version of dungeon master and i have to admit i love it!!!!

has anyone here finished it or even play it ? i am stuck at the part where there is many little mazes , each of them giving you a gold key, i have 3 gold keys but need a 4 for the door next to the stair case. its not required to goto the next level but i want it just incase there is something i need later on in the game
