This kind of thing often has the opposite of the intended effect. People then host mirrors of the original repo, and the press brings more developers to the project.

This sort of action by Nintendo and other companies is so short sighted. Bad press, a legal battle they couldn't actually win if it went to court, increased attention on the thing they're trying to hinder, etc. Its a stupid decision made by business people who don't know anything about tech, and who are disincentivized to care about the long term health of their brand.

I litterally had not heard of the emulator until now. Maybe I'll have to compile it and give it a spin now.
