Hey I am a fan of the game but am now stuck.I am stuck on the part with the wall with the twelve skulls on it in the dungeon. I have spoken to the man in the cell, the dial is stuck, I have completed the liquid maze. I know I have to use a syringe and I have seen the differences between the Turkish photo and the genevois photo. What can I do? Unlike the pc version there are no nails in the skulls.

I hope someone can help
