PSX controllers on a PC (parallel port)
The Playstation controllers are very well designed, are comfortable and they
work very well. That's why it's interesting to use a real playstation controller
on a PC (intead of using a cheap imitation). There are many adapters on the market
to do this. However, if you like electronic or want to save a little money, it
is possible to build one yourself.
I have done this for the first time when I bought the PC version of Final Fantasy 7. I
wanted to play the game with the original controller.
*I do not* have any schematics or information on how to build a usb version of
this adapter. Dont send me mail asking for this, I wont answer.
The Direct Pad Pro project provides a schematic to connect the controller to the PC Parallel port. Here
is a copy of it:
Comments and more details about the schematic:
The diodes used are the common 1n4148 or 1n914. It is possible that
1n400x diodes would also work(and many other types), but I have not tried. Also,
if you have a dual shock controller and want to use it, you will need to provide
an external 9 volt power source.
Hooking a second controller
Here are instructions to use two controllers on one port.
(Copy-Paste from DirectPadPro readme.txt file):
To hook up the second controller duplicate all connections except DB25-10
and DB25-12. For pad 2, replace the DB25-10 connection with a connection
to DB25-13, and the DB25-12 with DB25-15. Note that the parallel port
may not be able to supply enough power to run a second controller, and
you may only be able to run one at a time without using an external power
For Direct X games, you will need Direct Pad Pro. You can download
. This is the
file I downloaded from
when Direct Pad Pro was still available on this site.
As far as I know, there are 2 drivers able to make this adapter work
with Win2k and XP.
Please not that since I dont use WinNT/2000 or XP, I have not been able
to test any of these drivers.
The Linux kernel supports this adapter without any supplemental patch. If
you know how to use Linux, I think you should be able to discover how to
make this adapter work yourself. However, I will give more information(I'm not
the type to just say RTFM).
If the gamecon
kernel module is already compiled and available,
simple type this:
# modprobe gamecon gc=0,7,0,0,0,0
If you have a rescent kernel, try this instead:
# modprobe gamecon map=0,7,0,0,0,0
If the module does not exist, you will have to compile it yourself. When you
configure your kernel, select the following options:
- say Y at Input Core Support > Joystick
- say M at Character Devices > Joysticks
> Multisystem, NES, SNES, N64, PSX joysticks and gamepags
Next, compile and install your new kernel and modules. You should now be able to modprobe
One detail: The documentation says you must plug the controller *before* loading the
module, because the controller is detected at load time.
The file Documentation/input/joystick-parport.txt that comes with
the kernel source should be useful you if you need more help.
If you wish to write your own software or driver for a particular platform, here
is a file containing a lot of the information you will need.
The is also a C library that allows one to use memory cards and controllers
with this interface(or others). This library is open source, so you should
be able to port it to another platform quite easily. Here is the site where
you will find it:
PSX Peripheral Bus Library
Sometimes, even if built correctly, this adapter may not work. The cause of this varies.
A common problem is that the parallel port is not able to give enough power to
the controller. That's because the pc parallel port has not been designed to give
power to peripherals connected to it. This adapter uses a trick to do so: 5 bits are set
to a logic 1 level(5 volts) by the driver, and they are combined with the diodes to
give power to the controler. If the controller consumes too much current, the voltage
decrease and become too low. If this happens, you must find another source for the 5 volt. Using
the game port pins 1 and 4 (+5volt and GND) works well. Of course, there are many other places were
you can obtain 5 volts inside a computer...
If you have a laptop(or a modern computer(2004)), the parallel port maybe using 3.3 volts
instead of 5 volts. In this case, you will need to power the controller from another source
of 5 volts, and maybe you will need to convert logic levels with additional circuitry.
Also, if you use a cheap clone of the PSX controllers, it is possible that
it is simply not supported, but it has not occured to me nor to anybody I know.
