"Wheeler Dealers" is a 1978 simulation game developed by Danielle Bunten Berry and distributed by Speakeasy Software. It was originally distributed on cassette tape for an original Apple ][ with 16K. It came with special hardware controllers which were required to play the game. Without the controllers, you can control the game with paddles or a joystick by defining a directional movement (not button press) to each player. Some emulators allow you to control a joystick with the arrow keys.
