Just gonna point out that the Nintendo going after fanworks bit is a tad blown out of proportion, especially online. They're definitely known for being way too heavy handed (especially compared to the likes of Sega), but they're not exactly going after every fan project they see on the internet. Large sites whose entire purpose is to host fan games and mods for the Mario, Zelda, Pokemon, etc series have been up for decades without any issues, and most mods and homebrew projects for consoles older than the Wii U or Switch are going fine.
Unless a project is going viral in the media, raking up in a significant amount of money via a paywall or is directly competing with a current game, the chances of it getting shut down are incredibly low.
Nintendo also is responsible for keeping Dolphin off of Steam. Dolphin wanted to get on steam for improved steam deck integration and Valve reached out to Nintendo who said, essentially : Lol fuck no we will ruin your life
The courts have told Nintendo numerous times that they are in the wrong in this behavior and outlook. They have no legal means to keep Dolphin off Steam and it is a matter of judicial record that emulators are not an infringement of your IP on their own. Nintendo doesn't care and openly discusses their intent to make you suffer through lawfare. A just system would smack them down with a vexatious litigant label, but our system gives businesses infinite benefit of the doubt.
