I did, until I reread her post and saw that it actually said "Znes," so I deleted mine. Maybe you'll want to undelete it now to provide context to your edit though. Is there actually a NES emulator named Znes or is that just a typo for ZSNES like I originally thought it was?

also as far as NES emulators go I've been using FCE Ultra, but really they're all pretty comparable.
