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

	Arkanoid driver (Preliminary)


	Japanese version support cocktail mode (DSW #7), the others don't.

	Here are the versions we have:

	arkanoid	World version, probably an earlier revision
	arknoidu	USA version, probably a later revision; There has been code
			    inserted, NOT patched, so I don't think it's a bootleg
				The 68705 code for this one was not available; I made it up from
				the World version changing the level data pointer table.
	arknoidj	Japanese version with level selector.
				The 68705 code for this one was not available; I made it up from
				the World version changing the level data pointer table.
	arkbl2		Bootleg of the early Japanese version.
				The only difference is that the warning text has been replaced
				by "WAIT"
				ROM	E2.6F should be identical to the real Japanese one.
				(It only differs in the country byte from A75_11.ROM)
				This version works fine with the real MCU ROM
	arkatayt	Another bootleg of the early Japanese one, more heavily modified
	arkblock	Another bootleg of the early Japanese one, more heavily modified
	arkbloc2	Another bootleg
	arkbl3   	Another bootleg of the early Japanese one, more heavily modified
	arkangc		Game Corporation bootleg with level selector
