Question.

It should work for most emulators, but for any emulators that don't work try using GlovePIE:

Look around for the control settings. From there, make sure your controller is plugged in, and then configure the buttons by pressing the button on the controller that corresponds with the button listed.

It is different for every emulator. I suggest looking in the "help" document of whichever emulator you're trying to configure your controller for.

You probably should have done that before asking about it on here, dude. Keep that in mind next time you have a question. Check FAQs and help files first.
