Button mapping

[Drakaen391]

What can I use to figure out my controllers button map?

I have a generic PS3 controller (afterglow)

I tried to map hot keys the same as my PS3 controller, however it's not the same button mapping...

Thanks in advance

There's a file generated after the configure input emulationstation dialog. The joypad config files are located in /opt/retropie/configs/all/retroarch-joypads, if you were to compare two configs that you wanted to be the same. Since you're looking for hotkey changes, just make sure that for example, input_save_state_btn is set to the same value as input_r_btn assuming you want the default hotkey locations.

Wiki Page showing the default hotkey locations

For a quick reference and assuming all button values are the same between controllers, you can run diff CONTROLLERNAME1.cfg CONTROLLERNAME2.cfg to give you a quick listing of the lines that are different between each file.

I am wanting to use the PS button for the hotkey, but it doesn't match the brand name PS3 controller

You can use jstest /dev/input/js0 or js1, js2 etc... to determine the value of the middle button. Then you can type it into your retroarch-joypads config file.
