Button mapping on original Picade

Hello,
Im having trouble figuring out the correct button mapping on the Picade. I have the older version of the picade with the two volume buttons on the left.

The issue being, the way I have it mapped now I cant exit any games. Id rather start fresh, the right way.

Is there a visual layout of the correct button mapping for the Picade?

Thanks

I think most people use this (myself included)
