+****************************************************************************** + +Notes + +Real machine has some bugs.(escalator bug, sprite garbage) +It is not emulation bug. +Flipped screen looks wrong, but it is correct. + +Note that the game-breaking escalator bug only happens on an 8-way joystick, +it's safe to assume that this game dedicated cpanel was 4-way. + + +Stephh's notes (based on the game Z80 code and some tests) : + + - Accoding to the "initialisation" routine (code at 0x2a23), + the "Bonus Life" Dip Switches shall be coded that way : + + PORT_DIPNAME( 0x03, 0x03, "1st Bonus Life" ) + PORT_DIPSETTING( 0x01, "20k" ) + PORT_DIPSETTING( 0x03, "30k" ) + PORT_DIPSETTING( 0x02, "50k" ) + PORT_DIPSETTING( 0x00, "100k" ) + PORT_DIPNAME( 0x0c, 0x0c, "2nd Bonus Life" ) +

29c3), + there is a 'ret' instruction (0xc9) instead of 'retc' (0xd8) + that doesn't allow the player to get a 2nd bonus life ! + - DSW1 is read each frame (code at 0x2197), but result is + completely discarded due to 'xor' instruction at 0x219a. + I can't tell what this read is supposed to do. + +*****************************************************************************/ + +#include "emu.h"
