+This folder contains joypad configuration scripts, generated by EmulationStation's input configuration.
+They are read by openMSX at start-up and loaded automatically when the corresponding joypad is plugged in.
+
+If you wish to have a game specific joystick configuration, you can override the gamepad's configuration by:
+ * copy an already existing controller '.tcl' configuration file to the 'game' subfolder.
+ * edit the file and adjust the 'bind_default' commands or the 'joystick1_config' configuration.
+   See the openMSX documentation for how to use those commands:
+   - http://openmsx.org/manual/commands.html#bind
+   - https://openmsx.org/manual/commands.html#joystickN_config
+   - http://map.grauw.nl/articles/keymatrix.php
+ * rename the new '.tcl' file so the name is similar to the disk/tape/rom name (i.e. 'Metal Gear.zip' will load 'Metal Gear.tcl').
+   If you are not sure which name to use, start the game, then press 'F10' and type 'guess_title', followed by Enter.
+   openMSX will print the content name, which you can then use as a filename for the override configuration file.
+   NOTE: special characters '(:?/\*)', are automatically striped from the name so if your content file is 'ABC?.dsk',
+   then the configuration file should be 'ABC.tcl'.
