The dual game, Gremlin/Sega's Invinco / Head On 2 has been supported since version .029 ... starting back in 1998 or 1999.

I uploaded a scan of the page that has dips settings from the Head On 2 / Invinco manual...like shown below.

http://www.ebay.com/itm/GREMLIN-HEAD-2-A...=item1e661b3393

The dip switch is labeled SW1 in the manual and is listed as a 6 position dip switch for the pcb. It is located approximately at C1 on the pcb layout-schematics page. The dip switch settings are shown in the uploaded, oversized scanned page.

*example from another driver file....for reference for whoever does the updating*

PORT_START("SW1") // SW1 @ C1

Current dip settings from vicdual.c source file that should/could be updated with exact settings and appropriate description names (shown in oversized, page scan attachment).

1188 static INPUT_PORTS_START( invho2 )
1189 PORT_START("IN0")
1190 PORT_BIT( 0x01, IP_ACTIVE_LOW, IPT_UNKNOWN ) /* probably unused */
1191 PORT_BIT( 0x02, IP_ACTIVE_LOW, IPT_UNKNOWN ) /* probably unused */
1192 PORT_DIPNAME( 0x04, 0x04, "Head On Lives (1/2)" )
1193 PORT_DIPSETTING( 0x04, "+0" )
1194 PORT_DIPSETTING( 0x00, "+1" )
1195 PORT_DIPNAME( 0x08, 0x00, DEF_STR( Unused ) )
1196 PORT_DIPSETTING( 0x08, DEF_STR( Off ) )
1197 PORT_DIPSETTING( 0x00, DEF_STR( On ) )

imo...the description should be "Number of cars" for Head On 2 while "Number of firing bases" should be used for Invinco.

Along similar line with the previous post with Deep Scan / Invinco color prom 316-0246.u44 needing to be renamed (corrected), Invinco / Head On 2 has a color prom. It's function should be noted as a color prom.
