 ## Config
 
-### EMULATE_JVS
-
-This turns on the JVS emulation layer, which will use X11s input capabilities to read your mouse/keyboard. When this is turned off the JVS traffic will be passed through to a serial port defined by `JVS_PATH`.
-
-### JVS_PATH
-
-This defines the path of the serial port that is connected to the JVS IO.
-
-### FULLSCREEN
-
-This defines if the game should open in full screen mode.
-
-### EMULATE_RIDEBOARD
-
-This turns on the Rideboard emulation layer used in the games The House Of The Dead 4 Special, and Let's Go Jungle Special!
-
-### EMULATE_DRIVEBOARD
-
-This turns on the Driveboard emulation layer used in the games Outrun 2 SP SDX, SEGA Race TV, Initial D 4 and Initial D 5.
-
-### EMULATE_MOTIONBOARD
-
-This turns on the motionboard emulation layer used in the game Outrun 2 SP SDX in its SDX setting.
+A default configuration file is provided in `docs/lindbergh.conf`. It should be placed in the same folder as the game is run from. If no config file is present a default setting will be used.
