Reply To: Where is the experimental menu?

[herbfargus]

Depends on what version of retropie you’re using. Newer ones have a retropie menu in emulationstation with an option to get into the retropie setup script. In the setup script option 4 is the experimental menu (if you don’t have an RPI 2 the Sega Saturn isn’t going to work at all and even with a rpi2 it still barely even functions if at all)

If you have an older build you can access the setup script from the terminal

cd RetroPie-Setup
sudo ./retropie_setup.sh

es_systems.cfg is located at /etc/emulationstation/es_systems.cfg
