Update EmulationStation from RetroPie-Setup for enable
New function Kiosk Mode for EmulationStation permit to limt configuration option for prevent accidental delete of roms or change in settings
To switch the UI mode from Full to one of the limited modes, a new menu option was implemented under UI OPTIONS
Switching back to the Full UI Once you are in one of the restricted modes, the UI options (where I put the UI Mode selector), is not shown anymore. So how to return to the full UI once your in kiosk mode? Well one way, is to go to the /home/pi/.emulationstation/es_settings.cfgfile and edit the UI_mode value manually:
Alternatively, you can use a pre-defined passkey sequence that you can enter while you are anywhere in the ES ui. The default passkey is [up,up, down, down, left, right, left, right, b, a] which some of you might recognize as the Konami cheat code from olden-times. This sequence can be changed in es_settings.cfg if need be.
