This gives you the ability to connect a new controller or remap an existing controller to your preference.

From this menu, you can define one mapping per controller. As a result, choose wisely the mapping that will fit most games naturally. The problem we have in the emulation world is that there is not such thing as one unique mapping for all emulated systems. Nintendo, Sony, Sega, Microsoft have all chosen different layouts… plus the multiple arcade systems that Batocera supports: you get the idea.
