Controller overlaysLink

Mattel Intellivision games were often meant to be played with game-specific cards overlaid on the numeric keypad. These overlays convey information which can be very useful in gameplay. Images of a limited selection of Intellivision titles are available at: http://www.intellivisionlives.com/bluesky/games/instructions.shtml

ControlsLink

Definitions:

  • Mini-Keypad - Allows the user to view and select keys from a small Intellivision pad in the lower corner of the display.
  • Controller Swap - Some Intellivision games expect the left controller to be player one, others expect the right controller. This isn't a problem if you have two controllers (and don't mind juggling them) but users with only one controller or using a portable setup would be effectively locked out of some games. Controller Swap swaps the two controller interfaces so that the player does not have to physically swap controllers.
