/*
	Preliminary driver for Samurai, Nunchackun, Yuke Yuke Yamaguchi-kun
	(c) Taito 1985

	Known Issues:
	- some color problems (need screenshots)
	- Nunchackun has wrong colors; sprites look better if you subtract sprite color from 0x2d
	- Yuke Yuke Yamaguchi-kun isn't playable (sprite problem only?)
