These games seems have 2 DIP Switches, DIPSW-A and DIPSW-B
Game reads these switches at port C000h (16 bit) with two calls (subroutine 0EF522h [totmejan])

What I found out:

DIP-SW A:

# - Dip Switch name on Mame; Tested/Confirmed Effect 0 = OFF, 1 = ON

0 - 0 ;Seems unused

1 - Unknown OFF/ON; COIN/CREDIT
2 - Unknown OFF/ON; COIN/CREDIT
3 - Unknown OFF/ON; COIN/CREDIT
4 - Unknown OFF/ON; COIN/CREDIT
	4 3 2 1 <- DIP NUMBERS (5 4 3 2 on DIAG. MENU)
	----------------------------------------------------
	0 0 0 0 : 1 COIN 1 CREDIT
	0 0 0 1 : 2 COINS 1 CREDIT
	0 0 1 0 : 3 COINS 1 CREDIT
	0 0 1 1 : 4 COINS 1 CREDIT
	0 1 0 0 : 5 COINS 1 CREDIT
	0 1 0 1 : 6 COINS 1 CREDIT

	0 1 1 0 : 1 COIN 2 CREDITS
	0 1 1 1 : 1 COIN 3 CREDITS
	1 0 0 0 : 1 COIN 4 CREDITS
	1 0 0 1 : 1 COIN 5 CREDITS
	1 0 1 0 : 1 COIN 6 CREDITS

	1 0 1 1 : 2 COINS 2 CREDITS
	1 1 0 0 : 3 COINS 2 CREDITS
	1 1 0 1 : 5 COINS 3 CREDITS
	1 1 1 0 : 8 COINS 3 CREDITS

	1 1 1 1 : FREE PLAY

5 - Unknown OFF/ON; MIN CREDIT FOR START
	OFF: 1 CREDIT TO START
	ON : 2 CREDITS TO START

6 - CROSS HATCH TEST OFF/ON - Same

7 - Unknown OFF/ON

DIP-SW B:
# - Dip Switch name on Mame; Tested/Confirmed Effect 0 = OFF, 1 = ON

8 - Unknown OFF/ON; Player start points
9 - Unknown OFF/ON; Player start points
	9 8 <- DIP NUMBERS (2 1 (DIP-SW B) on DIAG. MENU)
	------------------
	0 0 : 1500 Pts
	0 1 : 2000 Pts
	1 0 : 1000 Pts
	1 1 : 3000 Pts

10 - Unknown OFF/ON; ???
11 - Unknown OFF/ON; ???
	[totmejan] Game definitely uses these, reads these 2 bits and stores at address 01A28h as 0-1st bit;
	Sub-routine at E7C19h does some arithmetic operations depending on these.
	I cound't understand whats going on. Call performs just before dealing tiles.

12 - Unknown OFF/ON; DEMO SOUND
	 OFF: Enable
	 ON : Disable

13 - Unknown OFF/ON; ENABLES/DISABLES EXPLICIT SECENES
	 OFF: ENABLE
	 ON : DISABLE

14 - Unknown OFF/ON
15 - Unknown OFF/ON

Original H/W Doesnt seems to have these switches and onward
16 - 1       OFF/ON : ADD CREDIT SLOT 1?
17 - Unknown OFF/ON : ADD CREDIT SLOT 2?
	 Switching these 2 ON and OFF does same effect as inserting coin

NOTES:
All adresses belongs to MAINCPU

TRIVIA:

Diagnostic Menu
	Press and keep P1 Start and Reset
	You'll see cross hatch test screen, then press P1 Start again.

Secret menu hack [totmejan only] (I couln't find official way to enter, so it's a hack):
	Mame internal debugger:
	PC=ECFFD ; 'SECRET MENU'
	Keys: BACKSPC, ENTER, Z, P1 START

	PC=E2EE2; 'TODAY: DATA' screen
	Keys: Z

	PC=ECC72; 'HMODE' screen
