Raspberrypi zero !WH

Hi there.
I'm new user here.
I'm gonna use my old rpi0 as simply arcade emulator.
So , to achieve it , I need to configure GPIO as input encoder 2 joystick , 8 button per player and HK button.
Can some one link or explain me ho to do this?
attached below a pic of GPIO wanted :

Thanks a lot & take care about yourself and others around you.

Are you asking how to wire your buttons/joysticks or how to configure the GPIO to take the inputs and make it work as a controller ?
The latter can be done by using the mk_arcade_joystick_rpi driver, which is included in RetroPie. For the former, I'll let somebody else chime in, since I don't have experience with the soldering/electronics part.

Hi.
Yes I mean active GPIO in order do this. Can you explain how do it?
About solder and wiring , I get it.

Many thanks

@Gnomx use ADAFRUIT RETROGAME software to encode buttons over gpio, it’s the easiest solution I’ve found and works great

Follow the link in my previous post to look at how the GPIO driver (mk_arcade_joystick_rpi) works and how it's configured. You can install it from the RetroPie-Setup packages (it's in the drivers section), so you can omit the installation part explained in the driver's documentation.

If you wish to use other method of GPIO-to-joystick mapping, there are other solutions, as @Capeman mentioned there's the ADAFRUIT RetroGame program (look it op) or GPIONext which offers similar functionality.

Ok thanks.
I think MK is ok for my purpose , but it's just for RPi 2th gen ,right?
SO as Capeman says , im gonna install ADAFRUIT RETROGAME , i should use existing pinout , or can use all pin on board?
Next,if I'm on old Rp0 without wifi connection , is it possible make an offline install?

No, it applies to any models after the 2 - the 1st model had less GPIO pins available.

I'm not sure, you should check the RetroGame's schematics, they might have a preferred wiring schema.

It depends on what packages you already have installed, but you can connect the PI Zero to the internet using a microUSB cable to your PC and configuring USB/Ethernet gadget mode (https://www.circuitbasics.com/raspberry-pi-zero-ethernet-gadget/).
