  	Irem M90/M97 system games:
  
  	Hasamu							1991 M90
  	Bomberman						1992 M90
  	Bomberman World / Atomic Punk	1992 M97
  	Quiz F-1 1,2finish				1992 M97
  	Risky Challenge / Gussun Oyoyo	1993 M97
  	Shisensho II					1993 M97
  
  
  	Uses M72 sound hardware.
  
  	Emulation by Bryan McPhail, mish@tendril.co.uk, thanks to Chris Hardy!
  
  Notes:
  
  - Samples are not played in bbmanw/atompunk.
  
  - Not sure about the clock speeds. In hasamu and quizf1 service mode, the
    selection moves too fast with the clock set at 16 MHz. It's still fast at
    8 MHz, but at least it's usable.
