For quality assurance, the company uses its official test software, sure, but for even more quality assurance, Nintendo also makes use of 160p test suite, a famous piece of fan software whose very notes hilariously state that it’s a piece of free software that features no warranty whatsoever.
Just so we’re clear, there’s absolutely nothing wrong about Nintendo using fanmade stuff – we actually love it. This is not the equivalent of, say, a hypothetical reality where the United States employed “ex” nazi scientists to create NASA, a similarly sounding organization that we just made up. This is an arguably a bit humiliating situation for Nintendo, sure, but one they should use to build some awesome bridges that’ll make use of the untapped capabilities of so many fans of the company. It’s time they stop trying to put their enemies in prison and start getting them jobs. They could start with Bowser (the hacker, not the turtle).
