F4-BMS 2.0 Technical Manual

In the above code fragment, each of the “call()” invokes the function to send the keystroke that

is mapped to the function that places the game’s HSI mode knob in the corresponding position.

The above code works well for a knob that is wired with four switch closure positions that are

mutually exclusive, one per placement of the physical knob. However, given the discrete

commands, it should be possible to make controller code that matches most wiring scheme

choices.

Modifying the Keystroke Mapping File

There is an excellent tutorial on adding new keystroke entries to the keystroke.key file in the

Falcon4\config directory at Frugal’s World:

http://www.frugalsworld.com/falcon4/keyboard.shtml

Please refer to that source for instructions on modifying the .key file to introduce new or different

key mappings.

The one piece of critical information missing from this tutorial is a list of the hex codes that are

used to “name” the keys in the .key file. The following table describes all the keytop names

recognized by the current game engine.
