"Emu Bias" option has been split into two separate options:
"System clock", which allows you to underclock the whole system to improve emulation performance, but breaks sound pitch.
"Sync threshold", which allows to reduce amount of synchronization between 68k and other chips to also improve performance.
Set both to 100 for best compatibility.
Added command line option support (see readme).
PAL/NTSC switch added (must reset game to take effect).
Sound and frameskipping code adjusted to work in NTSC mode.
Faked sound option fixed to emulate sound without outputting it.
Sound breaking problem was hopefully fixed.
Framelimiter fixed.
Added trace mode support to Cyclone. Some timing hacks added to make Project-X work.
GnoStiC submitted a few more optimizations.
