RetroPie - Hotkeys in retroarch emulator

Floob
This shows how to set hotkeys in RetroArch, and how to map joypad buttons to make them work. A useful example is to use the joypad to return to the EmulationStation menu, or to save and load games without needing a keyboard.

This is using RetroPie but should work with any RetroArch installation.

RetroPie hotkey script:

Main retroarch.cfg file:
https://github.com/libretro/RetroArch/blob/master/retroarch.cfg

Make sure you keep a keyboard key mapped to enable hotkeys as well as a joypad button version:
