Help with Leaf .a/.p engine?

[Meriel]

This is my first experience with hacking and stuff, so I'm really really sorry if I seem like a total moron.

Okay, I'm trying to extract the script of December When There Is No Angel. I've tried opening up the files with a hex editor, but I have no clue where the script file is and I need help. I've already tried reading the tutorials at insani.org.

Anyone want to help me please?

EDIT: Nevermind. I got it.

Hrmm..., if you wouldnt mind Meriel, write up what you did to figure it out as it may interest others.

It would be great if someone posted some info 'bout these file formats.

I have a feeling that information on these formats, in its full verbosity, would probably overflow the forum's allocated space ;o Leaf has one of the most complicated file formats ever with their .p/.a stuff.
