Configuring
===========
When first run, an example systems configuration file will be created at $HOME/.emulationstation/es_systems.cfg. This example has some comments explaining how to write the configuration file, and an example RetroArch launch command. Keep in mind you can define more than one system! Just use all the variables again.

When first run, an example systems configuration file will be created at $HOME/.emulationstation/es_systems.cfg. This example has some comments explaining how to write the configuration file, and an example RetroArch launch command. Keep in mind you can define more than one system! Just use all the variables again. Also, you can use multiple extensions - just separate them with a space, e.g.: ".nes .NES .bin".
If an SDL Joystick is detected at startup, and $HOME/.emulationstation/es_input.cfg is nonexistant, an Input Configuration screen will appear instead of the game list. This should be pretty self-explanatory. If you want to reconfigure, just delete $HOME/.emulationstation/es_input.cfg.
