There are two cleaners solution to do that: 1- catch the jump to the ROM address in QEMU and shutdown the machine, see https://github.com/vivier/qemu-m68k/commit/51cd57d1128059819038b9800455fbf794430c15 2- or as you do, write a fake ROM but use the VIA2 port B bit 3 to shutdown the machine see hw/misc/mac_via.c mos6522_q800_via2_portB_write(). Thanks, Laurent
