• PC-98 mode now supports joystick emulation. Joystick
  input is mapped through the DOSBox mapper to the
  PC-98 FM board where DOS games expect to see it.
• Added dosbox.conf option to select which PC-98 FM
  board to emulate.
• Fixed PC-98 FM code to enable the ADPCM and Rhythm
  FM channels.
• Re-ported Neko Project II FM board emulation, this
  time keeping the code intact and keeping the separate
  board emulations intact for PC-98 mode.
• VGA palette errors with Crystal Dream II fixed.
• PC-98 FM synthesis fixed not to initialize itself
  again when rebooting, which fixes a problem with
  garbled FM synthesis after rebooting.
• Removed some now-unnecessary SDL Video quit/init
  calls from Windows builds.
• machine=pc98 now starts entire emulation in PC-98
  mode instead of booting up in IBM PC mode and
  switching to PC-98 mode.
• Initial "BIOS" startup screen now operates in
  PC-98 mode when machine=pc98.
• Prefetch core debug code now disabled at compile
  time. Seems to be stable so far.
• Prefetch core now emulates partial load of the
  prefetch buffer on miss, and completing the buffer
  fill on hit, to better emulate (probable) 80486
  behavior.
• 486_prefetch is now a valid cputype setting, despite
  the setting having existed for years in the source
  code. Prior to this fix, 486_prefetch was ignored.
