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

3469 GAME( 1979, invho2, 0, invho2, invho2, 0, ROT270, "Sega", "Invinco / Head On 2", GAME_IMPERFECT_SOUND ) --
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.
