Gremlin/Sega's N-Sub has been supported for some time. Besides the missing cobalt, blue colors still missing as well as audio effects, the dip switch settings have not been supported either as shown in source file http://mamedev.org/source/src/mame/drivers/vicdual.c.html
iirc Someone may have looked over N-Sub dip settings earlier, but wasn't able to determine how coin board worked with N-Sub's main logic board....that's what I vaguely remember many years earlier. More vicdual hardware type dips settings later for this thread.
If wondering what exact colors should look like, here is an N-Sub flyer for reference. http://flyers.arcade-museum.com/?page=thumbs&db=videodb&id=2739
It appears all the roms for upright cab have been dumped, so it would be someone that can tell how video output for this game should work is still needed.
* currently in source file* 2208 static INPUT_PORTS_START( nsub ) 2209 PORT_START("IN0") 2210 PORT_BIT( 0x01, IP_ACTIVE_LOW, IPT_START1 ) 2211 PORT_BIT( 0x02, IP_ACTIVE_LOW, IPT_START2 ) 2212 PORT_BIT( 0x04, IP_ACTIVE_LOW, IPT_BUTTON1 )
2219 PORT_START("IN1") 2220 PORT_BIT( 0x01, IP_ACTIVE_HIGH, IPT_SPECIAL ) PORT_CUSTOM(vicdual_get_composite_blank_comp, NULL) 2221 PORT_DIPNAME( 0x02, 0x02, DEF_STR( Unknown ) ) 2222 PORT_DIPSETTING( 0x02, DEF_STR( Off ) ) 2223 PORT_DIPSETTING( 0x00, DEF_STR( On ) ) 2224 PORT_DIPNAME( 0x04, 0x04, DEF_STR( Unknown ) )
Fortunately, the Japanese version of N-Sub manual is online and it does have dip switch settings. The uploaded, scanned page of dip settings was extracted from the N-Sub pdf file that Al K. scanned many years earlier when he was running Wiretap. http://www.cityofberwyn.com/manuals/index.htm http://www.cityofberwyn.com/manuals/N-Sub.pdf
The 8 position dip swich is on a add-on pcb described as a coin calculator and part number is listed as 97201-P. It only deals with coin credits for handling coin inputs in both coin chutes. No other dip switches involved with N- Sub.
