Hi,
there was a bug in Atari ST version but I can not remember how to replicate exactly but it allow to multiple items in you inventory so you could find one piece of AmberStar and multiple it 12 times
!
Bug was when you save game and when ask for game disk to put data disk or something like that and items get duplicated in you inventory.
Maybe I will setup my old Atari ST again to try to replicate this bug exactly but neither way it was not very useful coz you could equip your party with 9999 gems, 6 scimitar, 99 hail storm scrolls... and that was not fun at all.
