Hello. I just wanted to ask if anyone has created a recent guide on what commands should be used to prepare Attract Mode as an optional frontend for the Odroid XU4 with Retro Arena (ARES) installed. I attempted to do it myself, but I received a message which read: "Failed to open X11 display: make sure the display environment variable is set correctly. Aborted."
If anyone has an idea of how to do this, please let me know. Thanks for your input.
