	*    TMC_Replay.s v4.2  coded by Sync/DreamDealers	*
	*		Last change : 4 August 1993		*
	*							*
	*	This replay is for 68020 and more only!!	*
	*		NOTE: VBR must be set to 0		*
	*							*
	*	bsr mt_init	: at the init (D0/A0-A1 used )	*
	*	bsr mt_music	: each vbl (D0-D7/A0-A5 used)	*
	*	bsr mt_end	: at the end (D0/A0 used )	*
	*							*
	*	Uses an interrupt of level 6  ( $78.w )		*
	*	DO NOT DISABLE the 13th and 14th bits of INTENA	*
	*	ALSO DO NOT DISABLE bit 9 of DMACON if ya want	*
	*	to hear something...				*
	*	Also uses the CIA-B timer B for initializing	*
	*	the samples while replaying			*
	*							*
	*  Suported commands :  0/1/2/3/4/5/6/7/9/A/B/C/D/F	*
	*			E0/E1/E2/E6/E9/EA/EB/EC/ED/EE	*
