This is the funniest thing. It didn't go through Valve's lawyers. There was no DMCA takedown. They asked Nintendo if they were comfortable with Dolphin being up, Nintendo said no and claimed a bunch of legal things but never filed a legal request.

But whatever, dude. I'm done summarizing the blog for you. Obviously you want to act like you know what's going on without doing research and I'm tired of doing it for you.

Nowhere in there does it say it's copyrighted. And, once again, in the blog they point out that you can't copyright a string of numbers and letters, which is all the key is. Additionally, they point out that the key has been freely shared in other contexts for years.

Idk, man. Go read the blog. They consulted with an actual lawyer before making any claim. Unless you'd like to pit your law degree against theirs? Are you a Nintendo lawyer trolling Lemmy on the sly?

No, it doesn't and no, it's not. The blog post from dolphin that I'm assuming this article is parroting articulates that perfectly.

I've got 1,000+ hours in MonHun if you wanna ask any questions!

Hopefully someone else can elaborate more, but just to start you can only progress the battle pass with a seasonal character, not the eternal ones. Seasons also have new loot drops. I'm also new, so I unfortunately don't know much more.
