Now, clicking on a link to Bimmy shows “This app is currently not available in your country or region.” This time, it wasn’t Apple that removed it but the developer. Over on MacRumors’ forums, the developer said it pulled the app “out of fear.” “No one pressured me to, but I got more nervous about it as the day went on,” it wrote.
Right. But there is no copyright infringement in an NES emulator, as long as no copyrighted games are distributed.
Emulation itself is not copyright infringement.
The recent issue with the Switch emulator was that they were distributing encryption keys along with the emulator. That wasn’t a copyright issue (encryption keys are not expression, therefore not copyrightable) but a CFAA issue.See other comments.None of that applies to the NES.
Yuzu didn’t distribute keys. You had to obtain them yourself. The problems were that:
Note that I don’t actually know for sure. This is just what I saw online.
Using leaked source code or binary firmware blobs are other common reasons emulators can violate copyright. I don’t know if this emulator did any of those.
I highly doubt it. The NES has been completely reverse engineered for decades, there really isn’t any reason to use proprietary code for an emulator for it.
The NES is the most basic possible architecture you could imagine. There’s no source code to be leaked here, there’s nothing you would even call a BIOS.
