Yes -- This is a way of hooking lighting up to stepmania.

***SOFTWARE:***

Add 

LightsDriver=Parallel

to your Data\StepMania.ini, in the [Options] Section.

It will use Port 378h for your lighting.

You may need to download parallel_lights_io.dll to your
Program/ folder to make it work.

***HARDWARE:***

This solution will only allow for all the lights to be on 
or off.

It also makes you have to have a power supply with ground 
in common with your computer.


Basic idea is that you take a light that is hooked up to
power,then cut the ground wire, and put the unit inbetween.

The ground of the computer must correspond to the ground on
the supply.  The ground on the light must hook to the drain
onthe mosfet on the parallel port.

A transistor can be uesd insted of a mosfet.  N-Channel 
mosfet and NPN transistors only.

If you want to follow these instructions using a transistor
the pins correspond as follows:
Base -> Gate
Collector -> Sourse
Emitter -> Drain

*05/25/2005 EDIT: If you are using NPN Transistors, make sure
to put a 1k-10k resistor inbetween your parallel port and the
transistor's base.

Ideal transistors for driving LEDs and other small lamps are 
RadioShack's 276-1617, available in most areas*

Make sure to have lightsdriver=parallel in your stepmania.ini.


These instructions I copied off my post on DDRMX.

all you need is a parallel port connector, a N-Channel 5 Volt 
Mosft, OR power NPN Switching transistor. and a resistor, 
anywhere between 50k - 5m (Any resistor that has gold and 
yellow as it's last two bands would do just fine.

This is a really simple solution and very in-elaborate. You 
could make it more advanced if you wanted by using more 
mosfets!!! This will only give you one light's output from the 
printer port. This shouldn't matter because under many 
conditions all the lights blink in unicon.

This is able to switch anything that uses a common ground with 
your compuer, i.e. computer neons, computer LEDs. If you have 
an external power source that is isolated you can use this too...

Everything's available at your local radioshack!

Port: 276-1547 ($1.89)
Mosfet: 276-2072 ($1.99) ... MAKE SURE it Vgs is 5V or less!!!
Resistor -- Pick any, I suggest either 100k or 220k ohms.


You will also need a little bit of wire.

Here's what you do: Bend the center pin of the mosfet up. Then 
hook the "Gate" pin to pin 6 of your parallel port. And put the 
"Source" in pin 20 of your parallel port. There should be no 
bending necessiary. Solder it in.

Then use a wire and hook pins 20-25 togeather, and bend the wire 
up so you can solder to it too. Solder wire to the pin on the 
mosfet you bent up, and to the wire hooked from pins 20-25 of your 
parallel port.

Then solder the resistor inbetween the gate and source of the 
mosfet. The direction does not matter.

Pins 20-25 should hook to the "Ground" or negetive or "common" in 
your computer or your power source. The pin off the mosfet should 
hook to the light's "ground".

Basically... most Computer neon/LED circuits go like this:

Computer Power:

Yellow o --------Switch--------|Device
Black o ------------------------/
Black o
Red o

What you have to do is cut the wire hooking to the black on your 
compy. The side that goes to your compy, hook to the parallel 
port pin. The other side that goes to the device, hook to the mosfet 
your bent up.



ALSO-- You have the option of using more than just one light.  You can
hook up to 8 ligths to the StepMania Lights.  Pins 2-9 coordinate to:
	LIGHT_MARQUEE_UP_LEFT,  (2)
	LIGHT_MARQUEE_UP_RIGHT,	(3)
	LIGHT_MARQUEE_LR_LEFT,	(4)
	LIGHT_MARQUEE_LR_RIGHT,	(5)
	LIGHT_BUTTONS_LEFT,	(6)
	LIGHT_BUTTONS_RIGHT,	(7)
	LIGHT_BASS_LEFT,	(8)
	LIGHT_BASS_RIGHT,	(9)


NOTICE!!! The parallel port is a VERY SENSITIVE port on the IBM/PC. 
BE CAREFUL WHEN DEALING WITH IT! DAMAGE TO IT CAN BE PERMANANT!

NOTICE!!! DO THIS AT YOUR OWN RISK. I CANNOT BE HELD RESPONSIBLE FOR 
DAMANGE TO YOUR PORT AND/OR YOUR COMPUTER! IF YOU ATTEMPT TO USE POWER 
FROM A DEVICE THAT IS OTHER THAN YOUR COMPUTER YOU WILL PROBALLY 
CAUSE DAMAGE! 



***EDIT 8/3/2005***

If you plan to use NPN transistors, make sure to put a 1k-10k resistor
between the output of the parallel port and the base of the NPN transistor.


ALSO -- If you are planning to convert a DDREx cab, read DDR Extreme Lights
Diagram (Courtesy of TPMWR from Tokyo Game Action).  Note that all lighting
pins are ground-biased, so you need to hook in a transistor or mosfet in
the manner described in this document. NOTE THAT GROUNDING IS A SERIOUS
ISSUE! MAKE SURE TO HAVE THE CABINET OFF UNTIL ALL GROUNDS ARE HOOKED UP
PROPERLY!
