Actually I have dabbled with VHDL in University and would love to do
more with FPGAs, but no, I have enough pet projects going as it is.
Perhaps in another life ;-)

Without even having seen the code I guess the remaining bugs are in
the processor flag handling. If you don't get them exactly right
everything kind of works, but then after a few million flawless
instructions some tiny thing breaks and things go down from there. I
remember tracing thousands of lines side by side with a real QL to
catch the remaining differences. But it did pay off, in the 18 years
since the first release only a handful bugs have been found in the
emulation core, most by George Gwilt. You should send him a board ;-)

Cheers, Marcel
