;-------------------BEY's Routine to Translate an Orginal Sound Command Into an Neo-Geo's sound CommandNo (ADPCM-Type A Format)
;if ( newByte==2 ) Play(hitSFX)			 ;  Hexa (0x02)/Original Phoenix sound code  ->Translate into-> (0x04)/Neo-Geo ADPCM sound!
;if ( newByte==12 ) Play(shield)		 ;  Hexa (0x0C) ->  (0x05)
;if ( newByte==80 ) Play(blow)			 ;  Hexa (0x50) ->  (0x06)
;if ( (newByte>101)&&(newByte<107) ) Play(laser) ;  sound between (0x66) and (0x6A) ->  (0x07)
;if ( newByte==143 ) Play(explosion)		 ;  hexa (0x8F) ->  (0x08)

:IMPORTANT:
;allow one or two vblank between sound init and sound start, so that the z80 can synch properly 


Problem ->Fred/FRONT!: I don't know, if it's necessary to InitSound (by send SoundID) at eatch time, before to sent a Sound CommandNo...for me, the Sound Code Ouput (SoundID=0x07 /Write), is Set by default...Must be confirme !

;possibility I've seen in FrogFeast code :
;	send_sound_command(SoundID + SOUND_ADPCM_FROG);
; or
;	send_sound_command(SOUND_ADPCM_OFF);
