This question has been asked more than once in the forums. The short answer is devs claim they are working on it, but say it could take years, if ever.
The honest truth however, (Stated by a developer.) is that they aren't willing dedicate the manpower to it because they have a larger user base on Windows. Linux users are being treated like second class citizens, even though many made the switch from Windows and already own a license.
Try emulation station until these guys otherwise get their head out of their ass.
