Mermaid
Sanritsu
driver by Zsolt Vasvari
Games supported:
* Mermaid
* Rougien
Known issues:
* stars playfield colors and scrolling are wrong in Rougien;
* Dunno where the "alien whistle" sample is supposed to play in Rougien;
* Incomplete GFX emulation in Mermaid (see MT07985 and MT08000);
* Mermaid has a ROM for sample playback, identify and hook it up (see MT07987);

Stephh's notes (based on the games Z80 code and some tests) :
1) 'mermaid'
- Player 2 uses 2nd set of inputs ONLY when "Cabinet" Dip Switch is set to "Cocktail".
- Continue Play is determined via DSW bit 3. When it's ON, insert a coin when
the message is displayed on the screen. Beware that there is no visible timer !
2) 'yachtmn'
- Player 2 uses 2nd set of inputs ONLY when "Cabinet" Dip Switch is set to "Cocktail".
- Continue Play is always possible provided that you insert a coin when the
message (much shorter than in 'mermaid') is displayed on the screen (there is
also no timer). Then when you press START, you need to press START again when
"YES" is displayed on screen (display switches 3 times between "YES" and "NO").
- Setting BOTH DSW bits 2 and 3 to ON gives you infinite credits and lives.
This isn't "Free Play" though as you still need to have one credit first.
This is done by setting "Bonus Life" Dip Switch to "None".
3) 'rougien'
- Player 2 ALWAYS uses 2nd set of inputs regardless of "Cabinet" Dip Switch.
- Continue Play is always possible provided that you insert a coin when the
message is displayed on the screen (there is a 6 "seconds" timer to do so).
- Setting BOTH DSW bits 2 and 3 to ON gives you infinite credits and lives.
This isn't "Free Play" though as you still need to have one credit first.
This is done by setting "Bonus Life" Dip Switch to "70k" and "Difficulty"
Dip Switch to "Hard".
