As more arcade hardware was emulated, systems often had similar controls. In order to emulate the movements of a joystick, pushbuttons, coin insert, etc., specific keys on the computer's keyboard were used. In the early days of arcade emulation, MAME was running on computers which, naturally, have keyboards. Usually, a keyboard interface is wired to arcade buttons which introduces another layer of abstraction to your configuration and additional considerations when you are trying to troubleshoot controls. In principle, a keyboard should be the simplest, most traditional interface to understand, but in practice, a keyboard is rarely used as an actual keyboard when playing games. Using a keyboard as a controller for emulation can be very easy, or it can be challenging and complex depending on your specific hardware and design needs.
