Use something like a dsub-9 connector and wire audio, video, 5V, and controller lines for how ever many you want. I'd wire it so the 5V goes into a digital switch or relay so that every unit except for the one with the game in it only has power going to the screen, speakers, and controllers.
To link my 2 ataris(not portable yet) I used a 25 pin connector but only used 18 pins. You wire 9 to p1 output and the other 9 to p2 input. Then you make a cable that take the p1 output and puts it to the p2 input on theother. You both need carts but atleast you can have your own screen.
I was going to solder wires from the A/v on the wierd jack thing and also a 5v spot I found to the three pins on the controller connection I'm not sure what to do about the master port.
Sorry to bring this up again but the N64's nearing completion and I still want to add the system link.I know you have to set it up where the slave is recieving the a/v and the master is sending it out so how do I set that up?
I'd set it up like this.
1:ground
2:audioL
3:audioR
4:video
5:7.2V
6:p1o
7:p2i
8:p3i
9:p4i
Basically, you wire the 7.2V to your screen so you don't have to turn both system on. I'm not sure what voltage the controllers require, so you might have to add another voltage line, or a regulator inside the unit.
Oh yeah, and p1o is inverted inside the cable with p2i.
I'll see if I can draw a wiring diagram if you need it.
A diagram would help, I'm kind of confused by what you're saying. I get pins 2-5. The batteries in the seconed N64 portable would take care of the controller, screen, and system power right? I'm still not sure on how you would setup the slave system though. Because you need it to recieve the the A/V and send it to the screen and stuff.
THis picture really isn't the best.
In this diagram, the second system uses the main systems batteries to power it's screen and controller. I think if you put a relay in it you could make it use it's own batteries to power the screen though.
Why don't the other 5 pins have anything connected. So is there going to be a slave and master or is it just setup with one port. What's the con. data. Sorry for all the questions I'm really confused.
the other 5 pins are connected, I just thought that it would be messy. They're just connected to the spots that correspond to their color. Con. Data is the controller datalines.
So the green lines are the first and last pins on controller one and two. So that wiould be the setup of the master port but how do you setup the slave now. Doesn't the 3.3 volts need to be connected too? One last thing I don't see a 7 volt spot on the mobo there's only 3 and 12
I meant the 12V line since it only requires 7.2V. Also, all controller data lines are the middle pins of controllers 1-4, not just 1-2. This would allow a 4 player game, although the battery drain would probably be too high if you didn't use a relay to activate the units internal batteries.
