You’re completely misunderstanding both the port tool, and the situation.
Valve has no issue with this at all. They don’t care about the IP aspect, and they don’t care about the tooling. But they are required by law to enforce copyright policing on their store. That’s just how it works.
Nintendo is the litigious one in the mix. They are known to go so far as to copyright strike a video for showing some of a game in the shot.
The linked project isn’t a port, it’s tooling to facilitate a port. There’s nothing Nintendo can do about it, because none of the provided data is owned by Nintendo. And it isn’t an issue with Steam/Valve, simply because it isn’t being sold on Steam. The moment someone tried to distribute the final game files, Nintendo would be down their throat. And the moment such a tool was added to Steam, it would likely face the same fate of Portal 64.
