Clash at Demonhead/Passwords

Secret password
There is a password which you can enter which puts you at the beginning of the game, but with maximum hit points, and all items. The password is nearly identical between the Japanese and American version, except that American passwords are two characters shorter. In Japanese, it means: Tensai wa wasureta kotowo omoidasu yo (天才は忘れたことを思い出すよ)
