Looks like someone is starting to image and share IIgs software in WOZ format. I reached out to the Floppy Emu author, as of now the 3.5" emulated drive can't use them. He said in theory it's possible. But he's currently focusing on another project. Hopefully now that the images are rolling out he will eventually support them. But for now, no go.
I'm not sure if wDrive has support for WOZ on 3.5. But given this is the first I'm seeing the images, I'd be surprised if it does.
