To the people that are using original controllers, how do you care for and maintain these ancient tools? I mean specifically the MK-1650 (large, 3-button) and MK-1653 (small, 6-button). In the post below I will have some useful links, but I would love to get a Controller Care Guide going here?
I have some "rubber pad replacements" I just installed, from mortoffgames.com. When I opened one of my controllers up, I was surprised that the rubber pads looked good. However, there were bits of plastic loose in the controller, where the plastic buttons had broken tabs, which (I now see) were meant to secure the buttons. The result was "depressed" buttons, which were not "upheld" by the small tabs. There was also a bunch of cat hair, and random bits of fluff. I feel I really need plastic button replacements, not new rubber pads; for this particular controller. Also, one of the rubber buttons I replaced worked worse than the original. I had to un-replace it.
I am wondering:
What are common issues with the controllers?
How do you fix each common issue?
What issues are unfixable?
Where can we get supplies?
General strategies for care and maintenance (I bet you have a collection of controllers and re-use bits of each here and there, right?)
What makes these near indestructible controllers so good?
