This looks fantastic! Ordering immediately.
As far as I know ScummVM’s switch version is written using the Switch home brew APIs, not Nintendo’s official ones, so it would never pass cert. And I believe there’s no real way for a developer to use it as a starting point to do an official port that uses the official APIs, because they’d have to publish their code publicly, which I believe would violate Nintendo’s agreement for how developers are allowed to use the official code. If I got the details wrong there I apologize, but that’s my understanding of the gist of it: It is a bummer.
