superqix.cpp: Add sqixr0 World/Japan V1.0 romset as a working clone, dumped from an early PCB.

Browse Source 
Renamed sqixr1, sqix, and sqixb1 set long names to include their version numbers.
Updated comments about sqixb1, which is in fact an exact copy of sqixr0 with one gfx rom split and the MCU replaced with a bootleg version.
Add notes about the greenwire fix on 7H on the V1.0 pcb vs the res/cap fix on later pcbs.
Add notes about V1.0 coin lockout being inverted compared to the later sets. [Lord Nightmare]

This happens in all sets. There appears to be code that would check part of
the MCU init sequence ($5973 onwards), but it doesn't seem to be called.
- sqixb1 might be based on an earlier version because there is a bug with coin
lockout: it is activated after inserting 10 coins instead of 9.
sqix doesn't have that bug and also inverts the coin lockout output compared
to the bootleg.
The older sqixr1 non-bootleg set does not have the 10 coin lockout bug
either, so it is possible that the bootleggers introduced it themselves, or
the bootleg is based on some sort of early (location test?) set (older than
the sqixr1 set) which we don't have a dump of.
- sqixr0 (World/Japan V1.0) (and sqixb1 which is the exact same ROMs but the
8751 MCU replaced with an 8031) has a bug with coin lockout: it is activated
after inserting 10 coins instead of 9.
This is fixed in World/Japan V1.1, V1.2 and the US set.
In addition, the polarity of the coin lockout on V1.0 (and sqixb1) is
flat-out reversed, so the pcb will not work in a standard JAMMA harness with
coin lockouts without inverting JAMMA pins K and/or 9. The hack below on V1.0
pcbs with the two wires connecting to IC 7H may have been a workaround which
involved a customized JAMMA connector/harness. How exactly is unclear.
- All Taito Super Qix PCBS are part M6100237A, and have a wiring hack on top of
component 7H (a 74LS86 Quad XOR gate):
(reference: 74LS86 pins 4, 5 and 12 are 2A, 2B and 4A respectively, none are
outputs)
The V1.0 PCBs have two greenwires running on the back of the pcb, connected
from 7H pins 4 and 5, to JAMMA pins e (GND) and d (unused) respectively.
This implies there was a hack done on the JAMMA harness connector itself
(possibly to invert the coin lockout value using one of the XOR gates
at 7H (or perhaps 7H controls the coin lockouts themselves?)) but what
exactly the hack does is unclear without further tracing.
The V1.1, V1.2 and US PCBS have two resistors from VCC to GND forming a
voltage divider on top of 7H, the resistor from VCC/Pin 14 to Common is
22KOhms, the other resistor is unknown and seems to connect to GND/Pin 7.
The center of the two resistors connects to one end of a 0.1uf capacitor,
the other end of the capacitor connects to 7H pin 12.
This implies some sort of brief/reset pulse generation or filter on pin 12.
Again, what exactly this accomplishes is unclear without further tracing.
- sqixb2 is a bootleg of sqixb1, with the MCU removed.
- Prebillian controls: (from the Japanese flyer):

something else. That something else is actually reading the system/Coin/Start
inputs from 0418, which the MCU normally reads from its port 0, hence...
