Yeah i managed to find the Amulet years ago when the game first came out, because in almost every Amiga Game i played, i made sure i did EVERYTHING and searched everywhere for anything. I would scour every game!. so i actually accidently found the Amulet and on my time finishing the game!.
As a result of this, ive never actually seen the bad ending!. I only found out that there were 2 endings until later, when an Amiga magazine mentioned it in a write up about Lionheart.
