Nekketsu Kouha Kunio Kun (bootleg)

driver by Phil Stroffolino, Carlos A. Lozano, Rob Rosenbrock

to enter test mode, hold down P1+P2 and press reset

NMI is used to refresh the sprites
IRQ is used to handle coin inputs

Known issues:
- flipscreen isn't implemented for sprites
- coin counter isn't working properly (interrupt related?)

Memory Map (Preliminary):

Working RAM
  $24			used to mirror bankswitch state
  $25			coin trigger state
  $26			#credits (decimal)
  $27 -  $28	partial credits
  $2C -  $2D	sprite refresh trigger (used by NMI)
  $31			live/demo (if live, player controls are read from input ports)
  $32			indicates 2 player (alternating) game, or 1 player game
  $33			active player
  $37			stage number
  $38			stage state (for stages with more than one part)
  $40			game status flags; 0x80 indicates time over, 0x40 indicates player dead
 $220			player health
 $222 -  $223	stage timer
 $48a -  $48b	horizontal scroll buffer
 $511 -  $690	sprite RAM buffer
 $693			num pending sound commands
 $694 -  $698	sound command queue

$1002			#lives
$1014 - $1015	stage timer - separated digits
$1017 - $1019	stage timer: (ticks,seconds,minutes)
$101a			timer for palette animation
$1020 - $1048	high score table
$10e5 - $10ff	68705 data buffer

Video RAM
$1800 - $1bff	text layer, characters
$1c00 - $1fff	text layer, character attributes
$2000 - $217f	MIX RAM (96 sprites)
$2800 - $2bff	BACK LOW MAP RAM (background tiles)
$2C00 - $2fff	BACK HIGH MAP RAM (background attributes)
$3000 - $30ff	COLOR RG RAM
$3100 - $31ff	COLOR B RAM

Registers
$3800w	scroll(0ff)
$3801w	scroll(300)
$3802w	sound command
$3803w	screen flip (0=flip; 1=noflip)

$3804w	send data to 68705
$3804r	receive data from 68705

$3805w	bankswitch
$3806w	watchdog?
$3807w	coin counter

$3800r	'player1'
		xx		start buttons
		  xx		fire buttons
			xxxx	joystick state

$3801r	'player2'
		xx		coin inputs
		  xx		fire buttons
			xxxx	joystick state

$3802r	'DIP2'
		x		unused?
		 x		vblank
		  x 	0: 68705 is ready to send information
		   x		1: 68705 is ready to receive information
			xx		3rd fire buttons for player 2,1
			  xx	difficulty

$3803r 'DIP1'
		x		screen flip
		 x		cabinet type
		  x 	bonus (extra life for high score)
		   x		starting lives: 1 or 2
			xxxx	coins per play
