Reply To: all the controller configurations options in RetroPie/EmulationStation

[herbfargus]

You are correct until the third part- the third option is an experimental module petrockblog is working on called inputstation- eventually in theory it should replace the beginning GUI you see when you boot into emulation station the first time. It will not only configure emulation station controls but it will also configure retroarch controls at the same time and will hopefully vastly improve the confusion of controller configuration. See this page near the bottom:
