Did the game come with a manual booklet? And if it did, did you check it out?
If the answers are yes and no, and if the copy protection is the same as in the MS/DOS version, you might just notice that your cry for a code wheel has been all for naught.
If there's no documentation at all, well... I don't know where to acquire a hard copy, but ReplacementDocs
repository has a wide range of digitized copies of manuals for various games. So while your collector-sense might not start tingling, at least it might enable you to play the game.
