The problem I have should be pretty simple but I can’t seem to figure it out or find a solution.
I have a Raspberry Pi B+ running RetroPie Image v2.3. I have it configured for multiple SNES USB controllers, the hotkeys are enabled and it all works quite lovely.
Now, I have an old SNES and I want to mount my Pi in there and make use of the old Reset and Power Buttons. I have all of the mechanical stuff sorted out (3D printing a front panel for the USB controllers and a the rear panel for power, HDMI and CatV and a straight wire in for the power switch). The Reset Button is going to be a momentary Normally Open switch but I don’t which pair of GPIO pins to use and know what lines of code to add to which config file. I would like the reset button to do what the START + SELECT combo already does; Exit the ROM back to the Emulation Station to select a different game.
Can you help at all? I’ve been down a google hole but I’ve had no joy. Thank you in advance.
My retroarch.cfg file is below and, like I say, works fine. Is this the file I would add to?
