	In the "bonus" modules there's a battmem.resource, which sets the
time at boot automatically.

	Of course.  The internal de-interlacer can't deal with more
than ~700 pixels horizontal or ~500 vertical (NTSC).  The modes you tried
were ~1280x400 and ~640x960.  The de-interlacer cuts out, so you get
straight interlaced video to the monitor.  Interlaced video flickers.

	The monitor don't have the pixel resolution to handle it.  1280x200/
400 is meant for getting finer edge resolution for things like character
generation for video, ot really for general use (too imbalanced, and most
monitors won't allow showing all pixels).
