@adespoton thanks for the tip about ScuEMU. That's the file sharing problem sorted. Next question is why does Marathon (1 or 2) quit with error type 16. Also I'm not sure what the mouse input handling is like in MAME. For future reference https://wiki.mamedev.org/index.php/Driver:Mac_68K previously I'd been using BII to configure disk images then opening them in MAME.
