The following file can be found on the net so I (krupkaj) assume it can be distributed here:

Here are two separate instruction sets to build the adaptor:

Method 1

Some games, such as Gauntlet II, allow four player to play at once. Here are the pin assignments for the cable. You need two female 9-pin plugs and one female 25-pin plug.

Joystick 3 Parallel Port
1 6
2 7
3 8
4 9
6 11
8 25


Joystick 4 Parallel Port
1 2
2 3
3 4
4 5
6 1
8 24

Parallel port pins 18-25 are all connected to ground.

Method 2

I missed a chunk of this thread so I don't know if someone posted thewiring diagram. If not then

Printer port           Joystick 1              Joystick 2
 1           ---------->    6
 2           ---------->    1
 3           ---------->    2
 4           ---------->    3
 5           ---------->    4
 6           ---------------------------------> 1
 7           ---------------------------------> 2
 8           ---------------------------------> 3
 9           ---------------------------------> 4
11           ---------------------------------> 6
24           ---------->    8
25           ---------------------------------> 8


Looking into the joystick socket

 1 2 3 4 5
  6 7 8 9

Looking into the printer plug

 1  2  3  4  5  6  7  8  9 10 11 12 13
  14 15 16 17 18 19 20 21 22 23 24 25
