What emulators/hypervisors did you test? Did you test with real hardware?
I tested with VirtualBox.
I'm not too surprised. These days Virtualbox supports disk sizes and types dyanmically; meaning if you throw a 360k image at it, it pretends to be a 360k drive; throw a 1.44mb image at it, it pretends to be a 1.44mb drive, etc.
It doesn't work (consistently) for 2.88mb images, though.
But as long as VirtualBox can sniff out the disk format, booting an older dos shouldn't be much of a problem for it. Now getting something like 2.x to a hardrive might be a challenge, of course...
