Yup, Sheepshaver has been pre-compiled for Windows for a long time and works great.

As for my previous tip about getting direct access to the host hard drives, I left out one line in the prefs file:

enableextfs true

I don't use any GUI here with SheepShaver as the only changes I usually have to make are adding new iso/hfv files, so I simply edit the SheepShaver_prefs file in Notepad.
