Couldn't attach it so I uploaded it on Mega. On the other thread someone had made more progress and could do this in a cleaner way than me but I don't know what is public from that work.
Also I didn't expect anyone to use this forum for this kind of thing so I hadn't uploaded it here. Anyway, hope it works, other people understood the instructions sooner or later.
