SkeleTony: I just typed 'X' when asked for the code wheel word and it worked fine.
Yesss... but as I recall, these games didn't immediately boot you out if you missed the copy-protection question. I think failing the question had other, more sneaky, repercussions. It has been a long time, so my memory might be foggy, but I would advise being careful.
Edit: Nope, just double checked. Apparently the original game copy-protection gave a player three chances to answer correctly before exiting the game. So, typing 'X' should be fine, if it didn't ask you for another code or boot you out.. Gotta love 25 year old foggy memories .. bah!
I do wonder what game I was thinking of though. I know there was at least one game that did that from that era...
