Joystick (MAME v202 ONLY)

Right CTRL = Fire Button
NUMPAD  2,4,6,8 = Directions

Pressing Joystick button (R Ctrl) on the title screen (in most games).
will setup the Joystick and disable the normal in-game keys.
only a reboot will fix keyboard controls in the game.

MAME v191
Pressing Left Ctrl (Fire Button) will make the game unplayable, as the Joystick isn't emulated.
*Right Ctrl MUST be used when the "Machine" requires the Control key.

Punchy.
The [GRAPH] key is now mapped to [#] not [F8].
This makes using Sausages and moving Up in the Hi-Score screen more accessable.
