More improvements to Noraut Poker driver [Roberto Fresca, Alan Griffin]
* Executed a trojan on 2 noraut systems to confirm the way 16x32 tiles are decoded. * Fixed the x-offset for 32x32 tiles lines. * Fixed the screen aspect and visible area. * Confirmed correct colors. No bipolar PROM involved. * Added Noraut Joker Poker hardware and PCB layouts. * Documented the discrete audio circuitry. Added a full diagram.

The strange issue is that some sets just configure the PPI to mixed mode2 and mode0 input.

it means that port A should be bidirectional and port B just as input. (port C as hshk regs).

So... it doesn't match the addressing through c1.
