	/* Sigh. CPU #1 reads the video controller register twice per frame, once at
       the beginning of interrupt and once near the end. It stores these values in a
       table starting at $163484. CPU #2 periodically looks at this table to make
       sure that it is getting interrupts at the appropriate times, and that the
       VBLANK bit is set appropriately. Unfortunately, due to all the device_yield(&space.device())
       calls we make to synchronize the two CPUs, we occasionally get out of time
       and generate the interrupt outside of the tight tolerances CPU #2 expects.

       So we fake it. Returning scanlines $f5 and $f7 alternately provides the
       correct answer that causes CPU #2 to be happy and not aggressively trash
       memory (which is what it does if this interrupt test fails -- see the code
       at $1E56 to see!) */
