This cartridge plays Badminton without on-screen scoring. There is no horizontal motion: the players can only move vertically. The only difference with Tennis (other than the lack of horizontal motion) is the hozitonal location of the players: they are very close to each other. The ball speed increments as far as the players catch the ball (the system produces a beep when the ball bounces on a player). The player who lost the ball can serve a new game using the push-button on his controller.

Interesting detail: the serve buttons also reset the ball speed circuit, which stores the ball speed as an electric charge in a capacitor. Because it takes about a second until the capacitor gets its initial charge, a fast game can be start with a short press on the serve button. A longer press will allow the capacitor to get its initial charge, thus starting a game at slower speed.

The circuit board of this cartridge contains very few components, since the game involves two players and the ball. The resistors set the players size, field and motion types. Same for the ball. This game differs from Sparring by only one difference: the wall is replaced by the second player. For this reason, both Sparring (Squash) and Badminton use the same circuit board, with only a few resistors placed at different locations to configure either the second player, or the wall.


Badminton game. No on-screen scoring.
