+The G-Net system uses a custom PCMCIA card for game software storage. The card is
 locked with a password and can't be read by conventional means.
 Some of the cards are made in separate pieces and can be opened. However some
 are encased in a single-piece steel shell and opening it up destroys the card.

+Some of the later games came packaged as a Compact Flash card and a PCMCIA to CF
 adapter, however these cards were also locked the same as the older type.
 The game uses an analog wheel (5k potentiometer) in the shape of a hand-held

+(like firing a gun) the car goes faster. If the trigger is pushed forward the car
 slows down. The controller looks a lot like the old Scalextric controllers (remember those?  :-)
 
+The controller is connected to the ZN2 main board to the 10 pin connector labelled
+'ANALOG'. Using two 5k-Ohm potentiometers, power (+5V) and ground are taken from the JAMMA
+edge connector or directly from the power supply. The output of the steering pot is
+connected to pin 2 and the output of the acceleration pot is connected to pin 3.
+The ANALOG connector output pins are tied directly to a chip next to the connector marked
+'NEC 78081G503 9810KX189'. This is a NEC 8-bit 78K0-family microcontroller with on-chip 8k ROM,
+256 bytes RAM, 33 I/O ports, 8-bit resolution 8-channel A/D converter, 3-channel timer, 1-channel
+3-wire serial interface interrupt control (USART) and other peripheral hardware.
