/******************************************************************

	Double Dragon 3						Technos Japan Corp 1990
	The Combatribes						Technos Japan Corp 1990


	Notes:

	Both games have original and bootleg versions supported.
	Double Dragon 3 bootleg has some misplaced graphics, but I
	think this is how the real thing would look.
	Double Dragon 3 original cut scenes seem to fade a bit fast?
	Combatribes has sprite lag but it seems to be caused by poor
	programming and I think the original does the same.
