-
- GX545 Scooter Shooter - (c) 1985 Konami
-
- It uses a mixed hardware based on Jailbreak and Iron Horse
-
-
-Stephh's notes (based on the game M6502 code and some tests) :
-
- - There is a leftover from an unknown previous Konami game
- when you enter your initials (code at 0x43f2) :
- if DSW2 bit 2 is ON and DSW3 bit 1 is OFF, you ALWAYS
- have to use player 1 controls !
- Here is what you have for example in jailbrek.c driver :
-
- PORT_START("DSW2")
- ...
- PORT_DIPNAME( 0x04, 0x00, DEF_STR( Cabinet ) )
- PORT_DIPSETTING( 0x00, DEF_STR( Upright ) )
- PORT_DIPSETTING( 0x04, DEF_STR( Cocktail ) )
- ...
- PORT_START("DSW3")
- ...
- PORT_DIPNAME( 0x02, 0x02, "Upright Controls" )
- PORT_DIPSETTING( 0x02, DEF_STR( Single ) )
- PORT_DIPSETTING( 0x00, DEF_STR( Dual ) )
-
- This looks the same, doesn't it ? That's why I've named them
- "Dip must be OFF !" to avoid confusion and people changing them.
- - The "Free Play" is correct (press a START button if you aren't
- convinced), but no text is displayed to tell that to players.
