System Link

How did you set up the relay inside. So do I not use a master and slave but instead use use four ports that can both recieve the data or send it out.

The relay would only be used for switching it so the batteries only power the screen and not the system.

Sorry to keep draging this on but the ports recieve and send data. So how do I setup the A/V on the ports. Cause I was going to solder wires to the port from the wierd a/v jack thing on the console. But I don't think the recieving end will work if it's setup like that. Also If I'm going to it for four systems wouldn't each port represent each controller port.

well I was thinking of 1 port and a 4-way cable to make things look nicer, but I suppose you could do 1 port for each unit.
Anyways, yeah, if you hook up the a/v on the jacks to the a/v on the n64 board, it will go bothways since the a/v on the n64 board has to be hooked up to the speakers and lcd anyway.

yea, one port would be nice and make a 4 way cable like the gba. I think I finally have everything figured out. Hopefully your diagram should work.

Here's something I just did a little while ago.

On the board there is a spdt relay, a pnp transistor, and a 3.3V ldo smt regulator. The regulator requires an external pass transistor, and by using a larger transistor, the regulator can handle more amps (4 according to the datasheet.) Unfortunatley I broke of the Vin pin of the regulator, but I was able to scrape away the solder to it.

I made it so that the relay normally transmits the batteries to the screen and the Vin on the regulator, but when it gets the +5V from the master unit, the relay switches so that only the screen recieves power. I'm not sure what voltages the controllers need, but if they need 3.3v, you'll either need to pull it from the master unit, use 2 relays, or use 2 3.3v regulators.[/img]

I'm probably an idiot for not noticing something that handles this, but just how do you handle the whole split screen thing on a console without system link? It makes sense on stuff like atari where there's know split screen, or on GBA or xbox or PS2 or something where it has built in system link, but it just doesn't make sense to me on something like N64. So, anybody willing to tell me how you get around that?

you still see the other player's side.

Yeah, you'll see the exact same thing that's on the other units, the thing about this though is that you won't have to try to do a 4 player game on a single 5" lcd, I'm not a sardine you know :
