@cyperghost yep, but the GitHub link references building it etc. I was just pointing out it's packaged already.

@mitu I got it working with the runcommand now. Only a small visual issue (no progress bar while downloading a game). But I found a bug in downloadAndExtract, and I opened a pull request :D https://github.com/RetroPie/RetroPie-Setup/pull/2628

np. Configuring controllers is explained here - https://github.com/retropie/retropie-setup/wiki/First-Installation - configuring additional controllers is under the "start" menu in ES (as you have found). Once configured in ES other emulators are set up automatically etc.

using /etc/module for module options has been deprecated for some time, but worked in Raspbian Wheezy. Now it doesn't - the wiki needs updating in this area - feel free :-)
