Nintendo couldn't do shit to Ryu either, except overwhelm them with lawsuits.
How much are they paying you to blatantly lie? Just because a corporation has billions to throw at frivolous cases doesn't mean that they're right, it simply means our court systems are fucked beyond repair.
Neither Ryu or any switch emulator has used Nintendo code. One of then simply boasted about a leak which got them in a lot of trouble.
You sure do seen to love a company that hates you. I mean, go try and post a video of you enjoying Mario kart on a switch, see how long it takes for it to be removed. Any game company that cared about its customers would let you have fun.
