/***************************************************************************
Galaxian/Moon Cresta hardware
NOTE: Eventually to be merged into GALAXIAN.CPP
Main clock: XTAL = 18.432 MHz
Z80 Clock: XTAL/6 = 3.072 MHz
Horizontal video frequency: HSYNC = XTAL/3/192/2 = 16 kHz
Video frequency: VSYNC = HSYNC/132/2 = 60.606060 Hz
VBlank duration: 1/VSYNC * (20/132) = 2500 us
Notes:
-----
- The only code difference between 'galaxian' and 'galmidw' is that the
'BONUS SHIP' text is printed on a different line.
TODO:
----
- Problems with Galaxian based on the observation of a real machine:
- Starfield is incorrect. The speed and flashing frequency is fine, but the
stars appear in different positions.
- Background humming is incorrect. It's faster on a real machine
- Explosion sound is much softer. Filter involved?
- $4800-4bff in Streaking/Ghost Muncher
Stephh's notes (based on the games Z80 code and some tests) for other games :
1) 'scramblb' and 'scramb2'
- Player 2 controls are used for player 2 regardless of the "Cabinet" Dip Switch
(check code at 0x1043 which changes player and routines that handle players inputs :
0x1741 UP and DOWN - 0x1796 LEFT and RIGHT - 0x24e6 BUTTON1 - 0x2615 BUTTON2).
2) 'tazzmang'
- If you press COIN2 during the boot-up sequence, you enter sort of "test mode"
where you can access to all inputs, but this doesn't give a clue about what
they do (only the status - 0 or 1 - is displayed).
- IN1 bit 0 has 2 effects : it starts a one player game (code at 0x5585),
but it also acts as 2nd button (bomb) for BOTH players regardless of "Cabinet"
settings (code at 0x5805 for player 1 and player 2 in "Upright" cabinet, or
0x5563 for player 2 in "Cocktail" cabinet).
