There's three switches that set the country, sw1-7, sw2-1 and sw 2-2. Since it crosses a dip switch, what's the best way to handle this? something like: sw 1-7 ON = USA/France/Germany/England sw 1-7 OFF = Denmark/Sweden/Italy/Spain sw 2-1 2-2 ON ON = USA/Denmark ON OFF = France/Sweden OFF ON = Germany/Italy OFF OFF = England/Spain the formatting here is lousy since I copy/pasted from a pdf manual: SW1-7 SW2-1 SW2-2 Country ON ON ON U.S.A. ON ON OFF FRANCE ON OFF ON GERMANY ON OFF OFF ENGLAND OFF ON ON DENMARK OFF ON OFF SWEDEN OFF OFF ON ITALY OFF OFF OFF SPAIN

It didn't end up as ugly as I thought it'd be.

You just have to set two settings instead of one.

Code

	PORT_START("DIPSW1")
	PORT_DIPNAME(0x01, 0x00, "Line Spacing") PORT_DIPLOCATION("SW 1:!1")
	PORT_DIPSETTING(   0x00, "1/6\"")
	PORT_DIPSETTING(   0x01, "1/8\"")
	PORT_DIPNAME(0x02, 0x00, "Form Length") PORT_DIPLOCATION("SW 1:!2")
	PORT_DIPSETTING(   0x00, "11\"")
	PORT_DIPSETTING(   0x02, "12\"")
	PORT_DIPNAME(0x0c, 0x00, "Character Size") PORT_DIPLOCATION("SW 1:!3,!4")
	PORT_DIPSETTING(   0x00, "Normal (80)")
	PORT_DIPSETTING(   0x08, "Condensed (132)")
	PORT_DIPSETTING(   0x0c, "Emphasized (80)") 
	PORT_DIPNAME(0x10, 0x00, "Always leave OFF") PORT_DIPLOCATION("SW 1:!5")
	PORT_DIPSETTING(   0x00, DEF_STR(Off))
	PORT_DIPSETTING(   0x10, DEF_STR(On))
	PORT_DIPNAME(0x20, 0x00, "Paper End Detector") PORT_DIPLOCATION("SW 1:!6")
	PORT_DIPSETTING(   0x00, "Valid")
	PORT_DIPSETTING(   0x20, "Invalid")
	PORT_DIPNAME(0x40, 0x40, "Intl. character set") PORT_DIPLOCATION("SW 1:!7")
	PORT_DIPSETTING(   0x00, "Denmark/Sweden/Italy/Spain")
	PORT_DIPSETTING(   0x40, "USA/France/Germany/England")
	PORT_DIPNAME(0x80, 0x00, "Select In") PORT_DIPLOCATION("SW 1:!8")
	PORT_DIPSETTING(   0x00, "Not Fixed")
	PORT_DIPSETTING(   0x80, "Fixed")

	PORT_START("DIPSW2")
	PORT_DIPNAME(0x03, 0x03, "Intl. character set") PORT_DIPLOCATION("SW 2:!1,!2")
	PORT_DIPSETTING(   0x00, "UK/Spanish")
	PORT_DIPSETTING(   0x01, "French/Swedish")
	PORT_DIPSETTING(   0x02, "German/Italian")
	PORT_DIPSETTING(   0x03, "USA/Danish")
	PORT_DIPNAME(0x04, 0x00, "Auto Feed Signal") PORT_DIPLOCATION("SW 2:!3")
	PORT_DIPSETTING(   0x00, "Not Fixed")
	PORT_DIPSETTING(   0x04, "Fixed")
	PORT_DIPNAME(0x08, 0x08, "Skip-over-perforation") PORT_DIPLOCATION("SW 2:!4")
	PORT_DIPSETTING(   0x00, "1 inch")
	PORT_DIPSETTING(   0x08, DEF_STR(None))

For fun segfaults I accidentally had a space in DIPLOCATION("SW 2:!1, !2") << before the !2 part since I've gotten so much in the habit of putting spaces after commas and it made the dip switch very loooooooong.
