I have been patching empw ad hoc. It would be too much trouble to
separate out all my changes so far. Highlights:
- Basilisk II (-b) for when you need more RAM (jankier UI, though)
- larger disk images
- support for partitioned images, *if* you create them yourself
- support for stderr and return codes (but not stdin yet)
- support for running from a subdirectory
- UNIX->Mac path conversion
