在Linux下的，接线好像跟windows的不同，不过确实没看懂，Select 1  Power Up 这些是SS手柄线的命名吗？

2.4.3 Sega Saturn
~~~~~~~~~~~~~~~~~
  Sega Saturn has eight buttons, and to transfer that, without hacks like
Genesis 6 pads use, it needs one more select pin. Anyway, it is still
handled by the db9.c driver. Its pinout is very different from anything
else.  Use this schematic:

    +-----------> Select 1
    | +---------> Power
    | | +-------> Up
    | | | +-----> Down
    | | | | +---> Ground
    | | | | |
  _____________
5 \ o o o o o / 1
   \ o o o o /
  9 `~~~~~~~' 6
     | | | |
     | | | +----> Select 2
     | | +------> Right
     | +--------> Left
     +----------> Power

  Select 1 is pin 14 on the parallel port, Select 2 is pin 16 on the
parallel port.

(pin 14) -----> Select 1
(pin 16) -----> Select 2

  The other pins (Up, Down, Right, Left, Power, Ground) are the same as for
Multi joysticks using db9.c

明白了，跟孙大师说的一样：）
对了，想了解下，这个接法是不能接双手柄吧？

你给的是DirectPadPro的，可是我的环境是Linux的，这个不兼容吧？
