@joeyperoni I use the GPIO method to control my build. Uses the Adafruit utility to mimic keyboard strokes, works well though did take a bit of setting up. Price is right of course. This is what i used as a guide. https://learn.adafruit.com/retro-gaming-with-raspberry-pi/overview
Im system is 2 player (6 buttons each), 2 start buttons, 2 coin buttons and an exit button.

@arkive thanks. Good to hear that is not a general problem. I ask for a new one.

@Stabbis awesome build with working buttons! Looks a lot cooler than mine!

@simonster yesss thanks so much! That was it, I had to renter the config and configure p2, I thought that for some reason if I re enter the config menu it would start over!

MAME libretro works with the arcade buttons, mame4all doesn't, neo-geo also works correctly, did not test with the rest.

Thanks a lot. :D

@mark1986 great, I will look into that, if I can of course because I have no keyboard to edit files with.

@Welc-ohm Je parle fracis seulment un peti pu. Pas problem, mon francis et trop mal ossi!

@edmaul69 ok i will try that and i tell you if it's work thanks for your times

@meleu @itsnitro Is there a way to connect my cartridge slot to the pi and get it to run? I would like to keep as much a I can original, and I will refurbish it a bit. But I'd still keep as much as I can original. Possibly even the remotes VIA an adapter. Even the metal plates I'll keep. So if there is a way to convert my own current slot to the adapter that would be great. (Also I live outside of the USA, so shipping can be very expensive.)

I successfully am using an NES Advantage on RetroPie 4.2.3

I have an NES to USB Adapter plugged into the Raspberry and connect the NES Advantage to the adapter.

I do notice a problem when I boot the Raspberry Pi and the NES Advantage has the SLOW button turned on. The Pi also did not detect the controller the first time when I had the SLOW button turned on. With the SLOW and TURBO buttons turned off the Pi detects the controller without any problem. Then when I load and start playing a game I can turn the SLOW and TURBO buttons on or off without problem. For me, it seems only when the Pi is booting that I cannot have the TURBO and SLOW buttons on or else the controller does not work (I also get stuck on EMULATION STATION LOADING screen when booting up with the SLOW button turned on).

@chubbz619

What do you mean, it detects it?

Can you give some information about your setup, are you using mk_arcade_joystick? How have you configured it? What hardware are you using?

Try filling out the info from the read this first post linked at the top of the page.

@Chillimonster you could use the 5v on the usb because it kills when you run a shutdown. Even if it is in "standby" and the power isnt fully cut off. Use the usb ground and 5v to power the relay and so when it gets power it flips the relay to turn on your light

@Hex @zulorumX
Take a look around here In last posting @meleu and me did resolve some problems with shutdown and escape emulators by GPIO signal.

well i just tried my wifi card on all three usb ports, and it can see the network without issues, so all three usb ports must be functioning.
I tried a confirmed working keyboard, and two confirmed working gamepads and they arent detected, not in a fresh instal or in the one with the GPIO keyboard.

very strange. I will open a new thread on this subject with a better title in the hope of getting some help.

@anasazi29 Broadly speaking, here is what you need to do: You need a python script that will watch a GPIO pin (that you have wired to a normally open switch like an arcade button--other wire to ground) such that when the button is pressed, the script sends a keypress. The key you send (suggestion: "ESC") would have to be picked up by the emulator as EXIT. So, you will have to go into your retroarch.cfg file, disable the hotkey function, and set the EXIT function to "ESC".

I know of a few ways this has been done in the past. One of the more popular is to use the adafruit Retrogame software. This basically takes care of the scripting process and leaves it up to you to configure what keys the GPIO pins trigger. Some folks use ONLY this solution for input control.

I also like mholgatem's GPIOneer which does the same thing, but uses a more elegant interactive configuration, then a web interface once it is setup. It is also easy to configure combo keys and to send full commands (I use it to send commands to increase and decrease master volume).

@Andrewpk200 said in Using multiple Controllers:

Also can the controls be set up to over ride on more game specific basis

Pretty simple for RetroArch: https://retropie.org.uk/docs/RetroArch-Configuration/#core-input-remapping

Never mind, worked it out! I had put the clock and latch the wrong way round! Swapped them over and it all started to work (except the start putton for some reason?!)
