	All games use a 6502 for sound (some are encrypted), all games except Cobracom
	use an Intel 8751 for protection & coinage.  For these games the coinage dip
	switch is not currently supported, they are fixed at 1 coin 1 credit.

	Meikyuu Hunter G was formerly known as Mazehunter.

	Emulation by Bryan McPhail, mish@tendril.co.uk

To do:
	Support coinage options for all i8751 emulations.
	Super Real Darwin 'Double' sprites appearing from the top of the screen are clipped
	Strangely coloured butterfly on Garyo Retsuden water levels!

  Thanks to José Miguel Morales Farreras for Super Real Darwin information!
