The Hudson Joycard is very similar to the standard Famicom controller, but has turbo switches for B and A. The cable also comes out of the top for greater player comfort.
Trivia
The Hudson Joycard was released in June 1986 and originally retailed for 1,980 yen.
Mitsumi, an OEM company who manufactured hardware for Nintendo, also manufactured the Joycard for Hudson.
The Joycard uses the same rubber membranes as standard Famicom and NES controllers.
