I grew up in Asia and had a chipped playstation 1 as a kid. It allowed it to read copies, was pretty standard stuff over there the copies could be found in legit stores and everything.
Anyway it started struggling to read the CDs. We figured out if we turned it upside down, it would be able to read them no problem. I suspect it was gravity making the lens come a bit closer to the CDs but don't know for sure.
It was certainly funny having it upside down, worked a charm.
Definitely yes for tractors, you should see John Deere's business practices and walled garden of maintenance and repairability! Peak capitalism right there.
