I'd like to help Nick (and have some fun reverse engineering), alas I've got no means of reaching out to them. Nick, if you're reading this, please leave some contact info. I figure it's a long shot, but... why not try?
Hopefully this submission is within the rules. If not, please let me know and I'll delete it.
If they didn't, they don't intend to be contacted.
Seems you may be out of luck.
