retroarch global configuration anybody know how to set it up?

[thcdgaf]

i was basically told you can setup global configuration for your controllers it automatically uses default of core for instance nintendo entertainment system have controllers set up for plug and play and whatever settings you set analog or dpad and shaders etc. without having to save in config as per core its idea for me since i dont like to setup each system the same lol just a thought anyone have any ideas of pointing it to rocketlauncher also so it runs in hyperspin thanx in advance
