Once again, 4am's Total Replay uncovered a bug in the emulation when its
replay of Firebug would lock up the emulation. This was caused by the
MMU not returning floating bus values from certain $C0xx soft switches.
Also, there was a bug in floppydrive.cpp which would cause the bitstream
to slip even when the simulated drive head never moved. This allows
Bard's Tale II to boot. Also, some minor fixes to allow the LSS to
honor a WOZ2 disk's "optimal bit timing" field. Border Zone & other
similar disks *still* don't work, so there's work still to be done
there...
Again, almost a year since the last commit. How the time does fly. :-/
