 Known bugs:

  MESS crashes if you for example use system GENESIS but forget to give CARTRIDGE argument
  as well, I hope to be able to fix this soon.

 History:

  000524 -Added a verbose options which will give some additional information.
  000525 -The frameskip code was ALL wrong, MAME/MESS wanted to know when to NOT render a
          frame, not the opposite which I would give it, fixed.
         -When MAME/MESS asks you to press a key, and no screen has been opened, a
          keypress will now be faked, and thus MAME/MESS will no longer lock.
         -The MAME/MESS startup text should now always fit on screen.
         -All Amiga keys are now mapped to MAME/MESS ones.
