There was one guy (
Kerbox), that wanted to reverse-engineer it for ScummVM, but instead he'll probably be integrating it to ScummVM's 3D counterpart Residual. Here's a link to a forum post:
http://residual.scummvm.org/viewtopic.php?t=9&start=13
Also, he released the code he worked on separetely, probably hoping to merge it one day and maybe even attract new developers, he made it public:

Direct link:
http://sourceforge.net/projects/tinselnoir
The project is a bit stale and very little progress is done at the moment, so people who are willing to work on it, at least that's way i understood it when talking to kerbox, would be more than welcome to join the effort. The means of contacting is via the #tinselnoir or #scummvm channel on irc.freenode.net . The prior isn't that active anymore.
Hope this was helpful.
Cheers
