Hi

I'm working on it ; 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)

I still have some uncommitted changes, I'll tell when it's OK to do more 
tests and to report differences.
