Really??? Wow! What model of Lisa, of Macworks, and of the Mac OS did you use?
The Lisa owner who sent me the screenshot in my original post tried exactly what you're describing: loading Macintosh disk images in the Macworks environment - and it didn't work. The Lisa just complained the disk was unreadable and offered to format it. Then just today, I finally got my hands on a Lisa for the first time, and repeated that test with the same result. It doesn't work. This was with a Lisa 2/10, running Macworks Plus, and with Mac system 3.2, and a Floppy Emu running firmware 1.0Q-F13. In the Finder, the computer acted like the disk wasn't initialized. I tried using a floppy testing program I'd written previously, and it showed that low-level calls to read a floppy sector were actually succeeding, but returning bogus data, rather than returning any kind of sensible error code. Bizarre.
If the Floppy Emu truly works on your Lisa, that is great news, and I'd really like to know how you did it! Adding the tag byte support should not be too difficult, I think, but I haven't looked at it yet since the Macworks test showed there was something more fundamentally broken that needed to be addressed first.
