The versions, I've played are not cracked. You must enter the correct code at the beginning of the game (both English and Italian).
Since the Amiga version gives you 25 IQ points for escaping Castle Brunwald regardless of the circumstances, it's possible to get 531 IQ points in one epsiode... BUT... the malfunction regarding the fight in the alarm room makes 790 the highest possible Series score! The game gives you 15 IQ points for beating the guard, but if you already solved the puzzle by giving him Mein Kampf, it does nothing to your Series score.
I need someone with coding skills to correct the errors (if it's possible to do so).
