@cwacha this is something that has always been a confusion due to the various hardware types. It had originally been left bottom, left top but that was confusing too depending on people's vantage point. It's most telling on the Xbox controllers where physically the shoulders are flat buttons whereas as the triggers are actually shaped like triggers as opposed to PlayStation controllers where the top buttons don't have any physical distinction other than placement. Shoulders and triggers are also more common in most gaming communities
In short: bottom = shoulders, if there only two like the SNES then they are shoulders. Top = triggers
I included the diagrams so they reflect the controls and verbage in emulationstation and so there can be no ambiguity.
