to connect more than 1 pad to the same LPT port, you just have to give it a separate data pin, correct? obviously more pads mean power concerns though...

If you find your notes, could you either post them or email them to me? I am interested in doing something to this effect, just with a different type of NES controler.

Yeah for every pad you add there is a different data line. It can be a bit of a nitemare trying to solder the wires from 4 pads onto an LPT connector tho ;)
You can always make a kind of adapter board to make it easier connecting alot of pads (I'll leave that to your imagination).
I personally think you should try and get a hold of a multitap (of sorts), the NES four score can be adapted but for software support (especially with 2000/XP) I would use a SNES multitap. I have one of those cheap third party multitaps that has 5 joypad connectors. It happily runs with 5 pads with no problems (on any comp I've tried it on), I did change one thing slightly though and took the power supply from the PC gameport. It seems to power the pads nicely.
For power you could use the a USB, PS2 (mouse or keyb), PC gameport or any of the internal connectors for floppy and hard disks (use the red wire), there are loads of places you can pull 5 volts from.

I built a single NES pad adaper today, and it works great! though I couldn't find 1N4148 diodes, I used 1N914, and they seem to work just fine. took a little bit of wrestling to get the windows joypad configurator to stop using it as an analog pad though...

Nice one mate.
Yeah I've used a few different types of doides and they've all worked so far. Almost every project I have encountered has need 4148 doides so I bought a truck load of them lol. So I always use 4148's now.
Whatt software are you using to run your pad NES-Luke?

Up until today I was using PSXpad, but it seemed to want to keep 4 buttons pressed at all times and took a lot of fighting to get working. Today at the suggestion of a friend, I tried PPjoy, and it works awesomely, much easier to set up as well.

Quote:Then you need to connect pins 18,19,20,21,22,23,24,25 of the DB25 connector all together, these pins are all ground. The ground wire of the NES pad needs to be connected to one of those pins. so on this part does the ground wire have to be connected to one of those pins or all of them

All of those pins should be connected together so you can connect ground to any of them :)

I know this is old and all, but I have a question about this. I have a Midi cord. Salvaged from an old game pad. Is it possible to use that instead? I am going to be modding an SNES controller to work on my NES so I am using the NES Cable, so I was hoping there is a way for me to just add in the new cable. this might help
