Software pic in post shows switches lit and button tester shows on as well. To me with little electronic knowledge it's like maybe a short causing them to show on.
It will take me a while to draw a scheme so I will look at that.


If you set the shift registers in MMJoy2 but you don`t connect the board with shift registers the MMJoy2 shows all switches as always ON. It seems it`s your problem so check the all wires properly. Or you didn`t set the MMJoy2 correctly, if you set 74HC165 but connect the board with 4021 is the same problem. Check it.
