Abstract: A joystick adapter is provided for mounting over the depressible buttons of a directional keypad on a video game controller. The adapter includes a joystick having a knob and a separable base. The knob is configured for manual manipulation, while the underside of the base is configured to contact and be supported by the depressible buttons of the keypad. The knob and base are pressfit together so that the individual components can be removed and replaced. The adapter further includes a clip having a shell that is supportable on the controller body. The shell defines an opening to receive the joystick therethrough with the knob above the shell and the base between the shell and the keypad. The adapter further includes an elastic T-shaped band that surrounds the bottom and sidewalls of the controller body. The band includes three arms with resilient openings in each of the arms. The openings are adapted to engage a corresponding tab projecting from the shell of the joystick adapter clip.
