2 Controllers Into 1

[SweBjorn]

I tried to make it so 2 controllers control 1 controller on the snes. I cut the wires and merged them together decently.

Like this:

|O..O|--------|
--------------------------D
|O..O|--------|

But it didnt really work. Up and green button worked on 1 controller. Nothing on the other. Any ideas?

I'm not sure I understand what exactly you're doing...can you post a picture?

[hailrazer]

You can't do that.

You would need a switch on the data line or 5v line to switch between the two.

[SweBjorn]

I dont want to switch between the two. I want to be able to make it so all singleplayer games can be played as two-players. Both players controll the same guy. Not sure if it's possible but this is how I did:

That works on N64.

Man I wish my post actually got verified. I wait like 8hours by my computer to respond. That guy on your n64 video plays all 4 player slots with 1 control. I want 2 controllers to play 1 player slot in the consol. So like one guy can shot and the other one moves the airplain for example. That way a singleplayer game can be a 2playergame

Not sure if it works though.

That's one controller controlling four characters not two controllers doing one input. The SNES controllers are pretty much two shift registers which clock out the status of the buttons. Knowing this there's an easy way to merge two controllers. I can't remember if the controllers are active high but if so just chuck both data lines (only the data, not the clock) into an or gate and it should work easy.

[SweBjorn]

I actually studdied OR/XOR/AND etc gates in school. Man, should have paid more attention to that I guess. But a straight on merge like I did in the picture would not work then?

Anyway to find out what type of thing I need to buy in order to make this work?

Disregard my previous advice. The buttons in the SNES protocol are active low, so you'll need to use a NAND gate instead. Something like a 4011 or 7400.

[SweBjorn]

Alright, tried google but could not get a picture of what that looks like. I only worked with gates in a computer program before. But I suppose I could just go into a electronic store and ask. 4011 and 7400 are a type of NAND gate?

Hmm, but if it's active-low he'd need an AND gate, wouldn't he? Or two NAND gates.

What a crazy idea! I'm curious how this turns out.
SweBjorn, if I was you I'd try to get a 7400 IC and wire it according to the picture attached.

The controllers have 5 different wires inside the black wire. Are you saying all of them should go into the same port, connected together?

I dont really understand the image you have attached. First time I'm going to do any work with this type of thing so need step by step instructions.

Yes, except for the data wire. *Usually* the data wire is the red one. You should connect the 2 red wires from the 2 SNES controllers to pin 1 and 2 of the 7400 IC. The red wire coming from the SNES console should be connected to pin 6 of the 7400 IC.

You also need to provide power to the 7400 by connecting GND (brown) and 5V (white).

[SweBjorn]

Is there anyway to make it so I dont need to fiddle with the consol?

I kinda want it like this if it's possible:


EDIT: After thinking some I retested my controls from my picture before. They work, kinda. Both players have to press LEFT to walk LEFT, same goes for all the other buttons. For me this means that 1 gate like the picture in this post should work. Right? A OR gate??
