I have been trying to set this up for about 3 days now. I have started from a Raspbian base using the setup script to do the install. It finished in a decent amount of time. However I still can’t get it to run. My raspbian is in the gui and I open terminal and type emulationstation and nothing happens except saying command not found. My linux isn’t the best but I basically followed the guide here. http://www.emulationstation.org/gettingstarted.html#install_rpi_retropie I did the compile everything yourself method.
I even tried that, while the emulation station runs on that it has very view emulators. I heard there was a huge list of emulators for this that get installed. I think at most I saw was like 9. Do these have to be added manually or something? The reason I was going with the Raspbian setup was to consolidate a few things. I am running a Pi 2. With Kodi running on it via Raspbian.
