For good. Because previously, they didn’t really do anything about the actual official site or creator. The file hosts, sure. Metroid Database’s version of the file, yeah. But DoctorM64 previously hadn’t heard anything from the company and hence decided to keep working on it regardless.
Unfortunately though, it seems like someone at Nintendo disagrees. So now his main blog got a DMCA notice, and he’s officially stopped working on the game as a result. It’s not hugely unexpected (in fact, a lot of people kind of thought this would have happened before the file hosting takedowns), but it’s still disappointing that such a great game is now basically dead.
So yeah, AM2R is now toast. There will be no more updates, and no more releases for any platform.
