Unlike the Street Fighter IV mini-arcade sticks, Namco Bandai's new Musou Controller keychains don't just play audio clips from the game; it lets you play full Street Fighter II matches! The small pad lets you select a character, input different moves, and even win a round without needing a display.

Depending on which of the three SFII controllers you purchase, you can play as Ryu, Blanka, Sagat, Ken, E. Honda, Guile, Chun-Li, Dhalsim, or Vega. And though I'm not sure how it works, if you have a friend with his own controller, you can apparently battle each other a versus match.

Namco Bandai also produced Musou controllers for shoot'em up Xevious and for Pro Baseball Family Stadium. Again, I've no idea how these work -- I assume the sound effects/game outcomes are chosen randomly? Either that, or there are miniature people inside the controllers acting out your directions and yelling out sound effects.

The Musou Controller line will release in Japan on March 20th for around ¥888, or around $9.83. Expect these to show up on import shops like NCSX, Play-Asia, and Strapya.
