If the image is still running (ie, you haven't shut it down since
deleting the directory) it may still have an open file descriptor for
the changes file, even though the directory entry is gone. If so, you
could write a DoIt to copy the contents to another file.

Otherwise, you'll have to rely on the decompiler.
