While in game with NES, SNES and Genesis I tried pressing F1 on the keyboard to get to the RetroArch menu (latest version of Retropie) and it does nothing. Tried two different keyboards and get the same issue. F4 works to quit emulation station. Any advice?
Do you have enable hotkeys enabled as shown at 20:26 in this video?
(Also check your retroarch.cfg file for the value as you may need to press ALT for example)
If you do, you need to press that first for it to work.
This is the value that should be default in /opt/retropie/configs/all/retroarch.cfg
input_menu_toggle = F1
