On a WOS forum post I saw mention of a new (?) emulator that the author would like people to try out/beta-test. There's just a zipfile as far as I can see, with no obvious link from the parent site. Anyway, the name is "EmuZWin" and it's on v2.0 (hence the question mark after the "new"). It's still under development (aren't they all), but could be worth checking out.
