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 _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
