arkanoid.c

这个是延伸mame的在wince平台下的游戏模拟器的代码

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

	Arkanoid driver (Preliminary)


	The location BFFFh can be changed to indicate the country:

	0x33 - Probably the world version (Copyright Taito Corp. Japan)
	0x76 - Japan (Copyright Taito Corporation with Japanese only warning)
	0x92 - USA (Copyright Taito America Corp. - Licensed to ROMSTAR for U.S.A)

	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
	arkbl2		Bootleg of the early Japanese version we don't have.
				The only difference is that the warning text has been replaced
				by "WAIT"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
	arkbl3   	Another bootleg of the early Japanese one, more heavily modified
