Hi,

I haven't tried it, but the idea of building an all-in-one computer that 
can work as an ST, an Amiga or some other platforms is really nice.

I once gave a look at the sources to see if they had some better 
implementations of some of the components used in Atari's emulation, but 
so far I would say it's not the case, they have a broad basis that 
should make most games work, demos should be more problematic due to 
lack of cycle accuracy in the 68000 emulation, as well as shifter being 
rather basic.

I would say it should be the same level of compatibility to what Hatari 
used to be around v0.70 or v0.80, which is good for most use, but still 
require a lot of work to complete all the cycle related stuffs and 
shifter behaviours.

But I think it's very interesting to have software and hardware 
emulation of the ST ; SW can be used to do some prototyping and to see 
how a possible implementation should be done. HW can then use it as a 
verified method to increase accuracy (the HW version in VHDL if often 
clock oriented, while the SW will try to avoid emulating at every cycle 
as it would require too much cpu power, but the logic of each component 
can definitly be shared).
On the other side, HW people will sometime reverse engineer some 
components using analyzer, which can be useful to describe some 
behaviour not yet correctly defined in the datasheets and help improving 
some not well known effect in SW too.
