I’ve managed to bring the DOS port of Frotz almost up to the level of the curses interface port. Loading zcode from a Blorb works, but very slowly. Graphics and sound in Blorb are not yet addressed, though old-style sound and graphics still kinda-sorta work. There’s still a problem with DOS Frotz crashing on real hardware and sometimes causing DOSbox to freeze.
I’m hoping to make a new release of DOS Frotz with version 2.45, which is expected when the Unix audio overhaul is done.
