Hopefully when I have more time (or someone else) can expand these directions.  Will be a work in progress until its done!  
 
This mod takes a Nintendo Four Score and modifies it to add 4x Vaus/PowerPad/Zapper capabilities.  The original 4x controllers and turbo functions are left intact.  It requires soldering in 3 chips and adding new controller cables.
 
The Four Score does not have all the pins in the controller cable, so you need to cut it off.  Don't forget to mark the wire colors on the Four Score board before cutting the cable!  Instead use some extension cables that have all the pins like: http://www.gametronex.com/NES-6ft...  You will have to chop off the socket end then trace the wire colors to the pins on the plug end.
 
The schematic is pretty simple so it could either be built on some perf board or just glued to the inside of the Four Score case.  The chips can either be 74LS or 74HC series.  All chips should also have a 0.1uF bypass capacitor on them.  One version is at: http://www.retrousb.com/images/fo...
 
After it is built you can use this test app: http://www.retrousb.com/downloads...  Each pair of numbers is the dial and button for one of the four ports.  You just want to make sure only one set changes as you move the Vaus controller.

4p zappers ftw!!! Looks like I need to buy some parts

Or do you have any plans to sell a parts kit for this?

So let me get this straight... this circuit piggybacks the Fourscore's stock circuitry, correct? Pretty much adds in the missing pin(s) the spinner or other accessories need to function properly. The 393's handle the timing, the 157's do the data handling.

Sounds neat, I'm in Have to order the parts, but I will let you know how it turns out.

EDIT: Plus a spinner test cart? It's a deal, it's a steal, it's the sale of the freakin' century!

Anyone want to make a modded one for cash for me, please pm me.

Four zappers? Just because of that, I want to program some 4-player zapper game for it in the vein of Carnival and Barker Bill's Trick Shooting (If only I knew how to actually program Zapper stuff )

Hey Vec, if you figure out this zapper business let me know. I have an idea that has been sitting on the shelf for a while, but it has been some time since I last looked into how to implement it.

How would four zappers work? The trigger is directly connected and the zapper relies on precise timing of the CRT beam. I'm not sure how you would wire one up.

Unrelated question but I thought I'd ask. Certain unlicensed and homebrew games access pins D3 and D4 on the NES player 1 port. I modded my AV Famicom to support Zapper on player 2 port without an adapter. It's simple. Just jump two wires from the EXT connector to the controller port. Is there anywhere to tap D3 and D4 for player 1 on an AV Famicom? Those ports do not appear to be included on the Famicom EXT port diagrams.

It would be cool to use this tech on a Famicom. Just sayin...

If I had a Four Score, and had the time to learn how to do it (not to mention be confident enough in myself to accomplish it), sure!

I'd certainly buy one if we were going to use it

While I love the idea of it, I never made myself to buy a four score because I rarely have friends to play two player games with, let alone four players.

I seriously doubt it. Nowhere to connect the D3 and D4 pins to.

Was afraid of that. Might try to figure something out anyways.

Holy crap dude. I just had an enormous brainstorm: 12 freakking Players! Here's how:

Famicom used the D1 inputs to add players 3 and 4. Since the Four Score Pro multiplexes the D3 and D4 inputs on each controller port, why not give each D3 and D4 pin on the Four Score Pro it's own port? That's 6 input pins, multiplexed makes 12 controllers. You'll still need a Four Score Pro, spare controller ports, the technical skill to wire your own adapters, 12 NES controllers, and obviously homebrew to support it all.

That would be so cool, but I'm assuming it would be hard to program for.

More controllers is basic. Thinking of a game concept that actually works with that many players is hard.

This.

I've been wanting to work my way into homebrew just for the fact that I would make more zapper titles!  Alas, for time is never on our side.

But I'm super stoked by this and will need to brainstorm!

I was wondering, since the zapper is so timing dependant, will the four score pro work with it? I just wish there were more two-zapper games. Zapper Pong was impressive, though.

The Four Score does not have all the pins in the controller cable, so you need to cut it off.  Don't forget to mark the wire colors on the Four Score board before cutting the cable!  Instead use some extension cables that have all the pins like: http://www.gametronex.com/NES-6ft-Extension-Cable-Bulk-p/reo...  You will have to chop off the socket end then trace the wire colors to the pins on the plug end.


 


The schematic is pretty simple so it could either be built on some perf board or just glued to the inside of the Four Score case.  The chips can either be 74LS or 74HC series.  All chips should also have a 0.1uF bypass capacitor on them.  One version is at: http://www.retrousb.com/images/fourscorepro.png


 


After it is built you can use this test app: http://www.retrousb.com/downloads/arkanoid4x.nes  Each pair of numbers is the dial and button for one of the four ports.  You just want to make sure only one set changes as you move the Vaus controller.

Does the AVS support this already?
