Start button alone keeps exiting games.

[abnorm999]

I have the latest version of Retropie installed on a Pi Zero W, with ROMs for NES and SNES installed and a single SNES USB controller. The problem Im having is no matter what I do, the Start key alone exits the game instantly, it dosent matter if I set the Select for a hotkey, or a different key, or even no hotkey at all. ROMs seem to work fine, if only I could start the game using the Start key. Anyone heard of something like this happening? Could it be a problem with BIOS files or something? Thanks for your help.

@abnorm999 Looks like a button mapping problem, the hotkey is either always active or you've unset it and then start acts as an exit key, though I don't think this would happen with a recent RetroPie version.
Re-map your button, skip the Hotkey mapping using a long press on A, then - when asked - choose to use Select as Hotkey. If that doesn't work, then please add more info as requested in https://retropie.org.uk/forum/topic/3/read-this-first and add the joypad .cfg file from /opt/retropie/configs/all/retroarch-joypads.
