Measure the voltage of the pin at the Amiga side if possible, it should be close to 5V by default and should drop to 0V when button C is pressed.

Have you included the diodes in your cable? They're primarily for protection of the C64 and aren't strictly necessary on the Amiga. I have found that it works fine on the A1200, but given that the button 2 input is an analogue input being used to detect a digital signal, its characteristics might change slightly from machine to machine, and the diode might be enough to upset it in some cases. Try remove / bypass the diode to pin 9 and see if that helps.

All six diode included in this cable and try to remove diode D6 is ok?
