Hmmm.. it connects thru the USB port on the computer right?
(this are the things used for PS and N64 emulation right?).
If so, I think you can, I mean, Windows will recognize the controller as an USB adapter.
What you can do is set it up on the computer and test it with the joystick utility to see if all the buttons work. (they are suppossed to).
If you are still not convinced, you can try going to:
http://www.ngemu.com
and check the forums there (I think it is
www.emuforums.com) and check if someone already made comments about this kind of products.!
