 It is the Joy Feather Wing. This is a PSP style analog joystick, so it's a potentiometer that goes from 0 to 1023, 0 to 1023 for X and Y axis, and it also has the four ABXY buttons. It also has a select button at the top. This is the original seesaw board, a little seesaw chip that is taking care of finding out what's going on on the board, in this case collecting the analog input and those five button presses, and then sending all that info over I squared C. What I'd do is make a little game console using the feather wing, and you can see there it's just connected over I squared C. Thumb stick there to rotate the little ship, and then I can use the B button to thrust, get away, and then I can do the old death blossom fire off, I think a maximum of five shots. It is the Joy Feather Wing.
