The only "special" instruction here is "stop 2300", it could be what
causes the problem in do_specialties. Maybe it's not frequently used in
falcon demos.
Try to comment the "stop" to see if the program runs without locking.
But I would not consider this to block hatari 1.5's release. Fixing
"stop" (if it's really the problem) involves a lot of work on
interrupts/exceptions and would take too much time for now.
