6Player
Required All Sega Saturn applications MUST be compatible with the 6Player,
Compliance Item regardless of the number of players supported by the application.
What is the 6Player?
6Player is a multi-tap hardware peripheral device that has six control
port inputs. By connecting a 6Player to both Control Port 1 and
Control Port 2, a maximum of 12 input peripherals can be connected
to the Sega Saturn.
Since the connection of a 6Player to another 6Player is not
supported in hardware, there is no need for the software to
support this.
