I don't know nor care if Nintendo plans to take these down. I just care that people continue to dismantle Nintendo's control over its software library, past and present
Not if they do it the same way as the OOT port. You provide the ROM, their code then picks it apart and puts it back together into an executable. There’s nothing for ninty to sue about.
You forgot one small detail, Nintendo doesn't need a legal basis to sue. They have more money which allows them to weaponize the legal system against anyone they don't like. Any small team like this cant even afford lawyers.
