This is the same as my Full Size Defender with added extras.

​

Changeable 4 to 8 way Joystick in the centre of the controller.

​

Push the switch at the back left or right to easily change the gate on the centre Joystick from  4 way  to 8 way. So not only use this controller for Defender and Stargate. But also,,

​

4 way game... (Pacman Mr Do! Frogger Dig Dug etc...)

8 way games...

2 way games...

​

As well as that I have placed buttons on each side that can be used as pinball flippers buttons or can be mapped to mame function buttons.
