I have the Mega Drive gamepad variation pictured in this article, where the d-pad is connected to a plastic circular piece on the back of the PCB where it triggers 4 rubber buttons.
But the down direction is very unresponsive. I’ve cleaned it well in the hopes that sticky plastic was the cause, but it wasn’t.
Any tips? Replacement rubbers, a piece of padding maybe?
The PCB is probably shedding at this point, so the contacts have a gap. You could try putting a nub of something in there for added pressure, but it surely still won’t feel right while playing.
Is buying a used controller out of the question?
The backup plan is to do either that or get an 8bitdo M30 with a retro receiver!
