4 Player Interface
4 Player Interface Thinking beyond the standards is our strength. Protovision extends your C64's capabilities with the 4 Player Interface. Connected to the user port of your Commodore 64 or 128, it provides two additional standard joystick ports for you to connect. This enables up to four players - with four real joysticks! - to play together on one computer!

Support:
BIOS/ROM Version: n/a

Q: Does the 4 Player Interface serve 5V on the joystick connectors?
A: Yes, there is a 5V output to both the joysticks.

Q: Is the 4 Player Interface supported by emulators?
