moved sega pico out of megadriv.c and into segapico.c, it really has nothing in common with the MD aside the CPU+VDP and should be properly separated. added skeleton 'Yamaha Mixt Book Player Copera' to the Sega Pico driver, it appears to be similar to the Pico but with extra sound hardware (a complete Sound Blaster clone) on the MB. Added a preliminary Softlist. Added board layouts for both [Team Europe]

	85	80000b byte Least significant byte of pen y coordinate.
	86	80000d byte Page register. One bit means one uncovered page sensor.
	87	00 - storyware closed

	92	writes write data to buffer.
	93	800012 word PCM control register.
	94	r/w For writes, it has following possible meanings:

	97	r - sample rate / PCM data type?
	98	0: 8kHz 4bit ADPCM?

	100	For reads, if bit 15 is cleared, it means PCM is 'busy' or

903		bit 7: pen button
904		800005 byte Most significant byte of pen x coordinate.

906		800009 byte Most significant byte of pen y coordinate.
907		80000b byte Least significant byte of pen y coordinate.
908		80000d byte Page register. One bit means one uncovered page sensor.
909		00 - storyware closed

911		either page 5 or page 6 is often unused.

913		r/w read returns free bytes left in PCM FIFO buffer
914		writes write data to buffer.
915		800012 word PCM control register.
916		r/w For writes, it has following possible meanings:
917		?p?? ???? ???? ?rrr
918		p - set to enable playback?
919		r - sample rate / PCM data type?
920		0: 8kHz 4bit ADPCM?
921		1-7: 16kHz variants?
922		For reads, if bit 15 is cleared, it means PCM is 'busy' or
