Have much fun with 4 players on Amiga!
With the 4-player adapter you can put additional 2 joysticks connected to the Amiga via the parallel port.
A list of Amiga games that works with the adapter, see in the Hall of Light.
Cable length: ca. 20 cm
2 DB9 ports (to connect joysticks)
DB25 (for the parallel port of the Amiga)
