Just wanted to give you a hint of a great add-on for Diablo 1 called "Risc's Diablo Improvements".
It adds several features to the original game (v1.0):
-Labels of items on ground (like in Diablo II)
-Monster healthbars (also like in Diablo II)
-Character level progression (^^)
-Number of monsters left in the current level
These are not cheats, but shouldn't be used on Battle.Net for your own safety.
Virus-free of course.
