Super Nintendo / Famicom Controller ports to Pi Zero GPIO (No ControlBlock)

[CeEeeEe4]

Hi everyone

I am having a bit of trouble, i have read numerous threads and guides about connecting the original controller ports directly to the GPIO pins on a raspberry pi without using Peter Blocks ControlBlock. But i am getting a lot of conflicting information as to which GPIO pins to connect to.

If anyone can help i need a clear working guide for both controllers to connect to the pins on a Raspberry Pi Zero. Any info or guides will be much appreciated.

Many thanks

I have seen several similar projects on these forums, can anybody point me to a working guide to wire up the original snes controllers to the Pi Zero GPIO pins using the controller port on the front of the console.?

Many Thanks

@ceeeeee4 You can use the gamecon driver schematic from its installer in retropie setup. I think the schematic pops up when you configure the default which are two snes controllers. I'm not sure if the pinout's changed from a pi zero to a pi2/3 but if it hasn't, it should work. More info here https://github.com/RetroPie/RetroPie-Setup/wiki/GPIO-Modules#gamecon_gpio_rpi

All 40 pin Raspberry Pi's (2/3/0/0w) use the same GPIO layout. The only difference is that you don't have the pins populated on the zero. So if you follow a pi2/3 wiring, this should work.

Thanks for the replies guys. i have the gamecon driver installed and can see the schematic of which GPIO pins to connect to, but which pins on the snes controller board do i use?

i would like both controllers working and the power LED if possible. would really appreciate the help.

many thanks

i have wired it up using the gamecon driver schematics. i have used these pins from the snes controller board (see pic). the LED lights up on power on, but i can only input the B button..

Any ideas??

@ceeeeee4 Do what I recommended you to do and use the schematic that pops up from the gamecon driver setup in retropie-setup.

I found my old post. These are the pins I used. Led works. It's for two snes pads:

Pin1=3.3v
Pin5=D2
Pin6=GND
Pin7=D1
Pin19=C1/C2
Pin23=L

thank you sir that has worked. i didint have both clock pins going to the pin 19.
