/* Super Lucky Roulette?
driver by Roberto Zandona'
thanks to Angelo Salese for some precious advice
TO DO:
- check palette
- check blitter command 0x00
- screen orientation is wrong (should clearly be ROT90 or 270 with blitter mods)
Has 36 pin Cherry master looking edge connector

NOTES:
blitter:
there are 4 registers:
reg[0] -> y
reg[1] -> x
reg[3] & 0x0f -> color
reg[3] & 0x10 -> y direction (to the up or to the down)
reg[3] & 0x20 -> x direction (to the right or to the left)
reg[3] & 0xc0 == 0x00 -> filled square
reg[3] & 0xc0 == 0x40 -> width used in y direction
reg[3] & 0xc0 == 0x80 -> width used in x direction
reg[3] & 0xc0 == 0xc0 -> width used in both directions
reg[2] -> width (number of pixel to draw)
with a write in reg[2] the command is executed
not handled commands with reg[3] & 0xc0 == 0x00
Stephh's notes (based on the game Z80 code and some tests) :
- "Reset" Dip Switch :
* OFF : no effect if NVRAM isn't corrupted
* ON : reset (at least) credits, bets and last numbers (clear NVRAM)
- When "Coin Assistance" Dip Switch is ON, you can reset the number of credits
by pressing BOTH "Service" (IN0 bit 2) and "Clear Credits" (IN1 bit 6).
- When in "Service Mode", press "Add Fiche" (IN1 bit 0) to increase value displayed in green after "R".
- When in "Service Mode", press RIGHT (IN1 bit 1) to clear statistics (only possible when "R00" is displayed).
- You need at least 5 credits for outside bets
