FREQUENTLY ASKED QUESTIONS Who are the creators of that great game? What are Cipher Keys for? What are the other messages in the Demo? How did you create the herocode calculator? Can you tell me the herocode formula? May I put the herocode calculator on my site? How did you take those videos and screenshots? What is a backdoor? As you see I'm not asked too many questions frequently. If you'd like to add any question, just send mail.
