For now, you need to use in ST/STE mode "--cpu-exact false" with
the new WinUAE CPU core.  This is what Nicolas said on that subject
(in "New WinUAE CPU core ST/e compatibility?" thread):

"lots of demos are already working now in your list, 
but the trick is that you should use prefetch mode, but not cycle exact 
mode (prefetch mode will be similar to the old UAE cpu, so it will be a 
reference to do regression tests ; WinUAE's cycle exact will be used 
later, but for now it will give wrong results in nearly all cases)"

Problem was with ST mode (TOS 1.04), new WinUAE CPU core and
C: being IDE image and HDDRIVER being run from floppy image.

(I was testing using IDE with ST)

And yes, it's a regression.  Needs to be re-checked after Nicolas has
fixed New WinUAE CPU core ST emulation more.
