Commodore 64 joystick adapters

Commodore 64 joystick adapters are hardware peripherals that extend the number of joystick ports on the Commodore 64 computer. The additional joysticks can be used on games with dedicated support for the specific adapter.

A number of different joystick adapters have been constructed for use with the C64. The Classical Games / Protovision adapter is by far supported by the largest number of games. While building instructions are available for most of the adapters, a few adapters are also available commercially. The adapters are also emulated in some of the C64 emulators.
