First of all I know this thread is ancient.
Anyway, I got one of the big old "duke" controllers at the local EB Games/Gamestop.
Soldered in the 9pin dsub connector and plugged in my old trusty WICO bat handle joystick (until I get an Arcade Turbo or Konix Speedking).
Everything works like a charm, also in WinXP using the XBCD drivers.
Now, this joystick has 2 buttons and I would like to be able to use both, so does anybody know where I have to solder the extra wire in the XBOX controller to make that happen?
I must say that it's great to be able to play Amiga and C64 games again with a "proper" joystick.
