MoltenGamepad | Flexible Linux input device translator , geared for gamepads

This is just a very quick introduction to get you on your feet and a little more able to discover what MG can do for you. When started, MoltenGamepad will create its virtual outputs, wait for input sources it recognizes, and will assign them to a slot upon their first event. WARNING: Out of the box, MoltenGamepad will only have the included wiimote driver. Unless you are using wiimotes, you'll need to create some config files describing a generic driver for your device before MoltenGamepad will do anything useful. (See documentation/gendev.md for details.) Community contributed configuration files can be found in the MG-Files repo. MoltenGamepad will also listen on stdin for user commands, such as changing a mapping or moving an input source to a different virtual output. When MoltenGamepad starts, take a moment to look over what is printed to get an idea of how MG initializes. Run print drivers to see the drivers you have loaded. Pick one and try printing its profile, ex print profiles wiimote. Next, go a head and connect a recognized input device. You should see it be identified and given a name. Try pressing a button on your input device, and you should see it get assigned an output slot. Try print profiles, and notice how there are profiles for each driver and each device. Changes to a driver profile will propagate to all connected devices and future connected devices! The gamepad profile will propagate changes to the appropriate driver profiles. Try changing an input mapping.
--mimic-xpad Make the virtual controllers appear to be wired Xbox 360 controllers, which most games (and Steam) expect.
--rumble if you want rumble and understand the risks
--load-plugins if you have any external plugins you wish to load.
