I think you can just SSH in and delete the config file:

opt/retropie/configs/%emulatorname%/cfg/default.cfg

@polish-potato See this topic https://retropie.org.uk/forum/topic/11837/disable-retroarch-joystick-reset-hotkey/5

@retroprogrammer No problem. The switch issue on Raspberry Pi is a need for everyone, not just RetroPie users. So, you can google the idea and find all kinds of examples of people using a simple momentary switch to short a GPIO pin to ground with examples of their custom scripts to monitor for that event. In most cases, examples in include a shutdown command, and that would be enough to do a soft shutdown or reboot. However, it is this command that you could replace with something more retropie-specific found in the threads here.

@jonnykesh Alright! That's not so bad :) Guess I should get familiar with gamelist.xml ...

Hey Simonster,

i know regarding third-party images. But any suggsetion or tipp would maybe help.

I will reconfigure the xbox controller

Thanks for help

Edit:

I´ve found the error.
Last night i installed over the retropie setup the xboxdrv - for whatever reason :-)

Now i uninstalled the driver and it works again with the xbox controller like before.

Thanks for the help

It could be that sixad isn't running. You could try this quickly to see if it fixes the problem.

From the wiki entry:
For bluetooth pairing to persist between reboots you need to make sure sixad is executed during startup. Exit EmulationStation and and edit rc.local.

shell
sudo nano /etc/rc.local
Add sixad --start & before the line exit 0 and save (ctrl-x then y)

@edmaul69 I know normally you're supposed to just wire the positive and negative ends to the appropriate pins on the control block. They're specifically marked. But im not sure what to do at this point. Thanks for your reply

unfortunately that doesn't seem to work. I need the input to recognize GPIO rather than the controller button.

Let me explain a little better...
I am using a Super Video Arcade machine as the case for my retropie set up. The goal of the project, like many have done, was to use the original on/off switch and reset button for all emulators.

So to do that, I have 1 GPIO input setup for the keyboard letter 'r' which I used as reset in my jzintv keyboard hack. It works great. So the Intellivision emulator acts completely like a real Intellivision complete with reset and on/off switch. I still have the keypad programmed for exit and all that, but I use the 'reset' button just for the sake of nostalgia.

So I'd like to do the same with all other emulators using the 'reset' button as the input for each emulator... I just can't get it to work.

Thanks.

@BuZz Fair enough. Sorry for my faux pas.

All right, I went into there and removed the line referring to "reset" from that file and saved it, but the SELECT button still resets the game. Also I still can not gain acess to the options menu through the joypad or keyboard, but only for the N64 emu.

Hey everyone, if this topic is too old I’m sorry and please redirect me if possible. Now to my issue, I tried the command above via command line and it says “command not found”. I did use a command to erase all the controller configurations to make the Os think it was a first boot, however, I don’t remember the command. Can anyone help with this? I can’t get any controller to work nor can I back out of a game.

@spannernick1 This blog post may help since you basically want to detect a GPIO button press and then send a keypress (Select+B) to reset the game.
