Well, what did you expect? One loop iteration will take approximately 5
milliseconds (since you're basically waiting for the 200 Hz counter to
toggle its sign), and you're looping with d1 = 12000 times ...
that makes 12000 * 0.005 s = 60 s = 1 minute.

So unless you really expect something different here, I'd say Hatari
works here as designed ;-)
