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

Changes:
	Mar 12 98 LBO
	* Added Sinistar speech samples provided by Howie Cohen
	* Fixed clipping circuit with help from Sean Riddle and Pat Lawrence

	Mar 22 98 ASG
	* Fixed Sinistar head drawing, did another major cleanup
	* Rewrote the blitter routines
	* Fixed interrupt timing finally!!!

Note: the visible area (according to the service mode) seems to be
	{ 6, 297-1, 7, 246-1 },
however I use
	{ 6, 298-1, 7, 247-1 },
because the DOS port doesn't support well screen widths which are not multiple of 4.

Joust2 Survival of the Fittest (1986)

All have two boards, a large board with lots of RAM and
three ROMs, and a smaller board with lots of ROMs,
the CPU, the 6821 PIAs, and the two "Special Chip 2"
custom BIT/BLT chips.
Joust 2 has an additional music/speech board that has a
68B09E CPU, 68B21 PIA, Harris 55564-5 CVSD, and a YM2151.

	Note: Please do not remove these comments in BETA versions. They are

	The encryption in this game is one of the silliest I have ever seen.
	I just wondered if the ROMs were encrypted, and figured out how they
	were in just about 5 mins...
	Very simple: bits 0 and 7 are swapped in the ROMs (not sound).

	Game does not work due to bad ROMs 16 and 20. However, the others are
	VERY similar (if not nearly SAME) to MAYDAY and DEFENSE ones (and NOT
	DEFENDER), although MAYDAY ROMs are more similar than DEFENSE ones...
	By putting MAYDAY ROMs and encrypting them, I got a first machine test
	and then, reboot... The test was the random graphic drawings, which
	were bad. Each time the full screen was drawn, the game rebooted.
	Unfortunately, I don't remember which roms I took to get that, and I
	could not get the same result anymore (I did not retry ALL the
	possibilities I did at 01:30am). :-(

	ROM equivalences (not including the sound ROM):
