Hahahah okay sorry, I felt like a dick for just laughing at you and not contributing anything. I went to GameFAQs and found an FAQ for your game. After much reading and MUCH, MUCH laughing at how RIDICULOUSLY COMPLEX the process of opening the door is, I decided to copy and paste it, word for word, for you to gape at. At least, I gaped at it.
