PlayStation Controllers
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
supply.
This interface has been built and tested by different folks on several
analog, digital, Sony(tm) and clone pads. Be aware that it is different
from SnesKey's interface, and that I will not be supporting SnesKey's
version since I cannot get it running reliably on my system.
The PSX-POV controller differs in that the d-pad is used as a POV hat
instead of the U-V axis pair. Most games that support POV hats will
work with this controller configuration.
If you've double-checked your wiring and are still having troubles,
try using the Advanced tab in the control panel to increase the PSX
scan delay, try between 3-10 and hit Apply!, then check the Configure
tab to see if the slowdown helped out.
Playstation Force Feedback
The optional line is only necessary if you are running a Dual-Shock pad
and want to use force feedback. If you're not running a dual-shock pad,
or don't want to use force feedback, don't hook anything up to the
optional (pad pin 3) pin/line.
Please take care when hooking up the 9V supply! Incorrect hookup may
cause problems with the pad or printer port. Do not attempt to power
the shock motor from your parallel port, this will not work and could
cause damage to the port.
I've only got a few games to test the interface on, and most work
just fine within the pad's simple limitations. A known issue with
Flight Simulator 98 is that after a crash no shock vibrations will be
felt. The simple workaround is to deselect "Crash Effects" in the
forces setup dialog. Other games, like NFS3, Viper Racing (demo),
and Rogue Squadron work fine with some tweaking.
**Note to Users of Genuine Sony Dual-Shock Pads
I've been informed that the first time force feedback is initialized
in the game your pads may switch from analog to digital mode. There's
no workaround other than to just reselect analog mode on the pad. My
clone pad uses a physical switch so it doesn't suffer from this
problem, nor can I debug it.
