+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
-control unit and a trigger (another 5k potentiometer) used for acceleration

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

+The ANALOG connector output pins are tied directly to a chip next to the connector marked
