Could I make start+select register a new button?

[Sudeten]

I remember reading that were people wiring two buttons to become a seperate extra button. Does it depend on the pcb?

I have a normal snes pad with 8 buttons wired, if i split start+select to a join at a 9th button, will that make a new button register on PC (through my snes to pc converter)?

Yes, you can do this if you’re using an OR logic gate and a common ground PCB. Method is below:

Wiring "Back' + 'Start' = Guide Button?

You could, sure, but that seems like massive overkill. The way I’d do it is with a (thinks about truth tables for a second…) OR gate. A single 50 cent OR gate chip like the 74-whatever-32, like this 74ACT32:

Click the datasheet link to make sure you grok the pin numbering, but you’d want to wire it up like so:

+5v from the 360 pad (red wire of the USB cable) to pins 4, 5, 9, 10, 12, 13, 14
Ground to pin 7
The signal wire for back to pin 1
The signal wire for start to pin 2
The signal pad for guide on the pcb to pin 3
Pins 6, 8, and 11 are unused outputs, so you probably want to clip them off as close to the plastic as you can to keep them from touching anything.

Wired up this way, when both start and back are pressed, then start, back, and guide are all pressed.

Connect the two buttons you want to make the combination into the two inputs of the OR logic gate (In the example, this is Pin 1 and Pin 2), and connect the output pin to the ninth button on the PCB (in the case quoted, the output would be pin 3).

But I read you wanted to use a converter, that makes it tougher :shake:

It would then really depends on if your converter supports the ninth button. Something like an FGWidget build would.

Hey, a question similar to this has been in my mind for two weeks now… but I want to make back+start = guide using a 360 controller with padhack.

Is there a way to achieve this?

I have an idea of wire the guide button and put the ground on the back button and the signal on start button so when I push both they will function as the guide.

Exact as what Nerrage posted.

Your way does not work.
You have Signal of Guide hooked to Signal of Start.
So that means every time you press the Start, Guide will pop up.

It does not matter that you have the Guide Ground wire separated.
The PCB you are using is Common Ground.
Start Ground is same as Guide Ground.

No. SNES pad has eight buttons. Converter checks those eight buttons, and reports whatever to the PC. You cannot make a new button out of nothing, on the hardware side.
What you propose might be possible using a software option. Check if the Joy2Key or similar programs have a ‘two buttons pressed is a new different key’ option. You need a software answer for this, not a hardware answer.
