Hi.
I've just joined this forum, but I actually saw this topic on google on the first day of it's creation, when I was seeing if there was a remake available for the ds.
I myself cannot help towards this, as I have no knowledge of programming.
But I'd like to give you this link which could help with reference:
http://www.ballisticpublishing.com/books/oddworld/
If you scroll down you can preview the whole book. It's rather small, but it has plenty of pictures.
Keep up the good work
